Introduction

The OSM community is made up of volunteer contributors from different countries around the world, who are dedicated to improving the world map. To contribute to OSM it is required first to have an OSM account and to be trained on how to contribute. These contributions are subject to validation in order to censor errors that may have crept in during the mapping process. Through this data quality internship, we had the opportunity to be trained on how to do the validation process.

Frequently observed errors

During the validation practice, for the tasks that were validated so far, here are the common mistakes made by the contributors that we noticed: - Buildings with non-square corners. However, the instructions for the projects always give clear directions for this! - Not completely mapped spots, especially in rural areas where there are circular buildings; - The use of some inappropriate tags, especially for circular buildings like “building=hut”.

Recommendations

Here are some recommendations we make: - Always remind contributors to a mapping project right at the beginning, especially beginner mappers that before locking a task into a project for mapping, first read the project instructions carefully; - Validate the tasks in time, so that the given remarks help the cartographers to improve; because a remark given after 1 or 2 years in my opinion has lost its meaning. Thanks again HOT for this good opportunity where we are being trained and informed a lot.

Project: Uganda 2022 Ebola Outbreak - Kitumbi Subcounty Kassanda District Project

Starting today with reviewing my notifications within the HOT Tasking Manager.

The following tasks have now been verified by moderators and are completed for the project:

  1. Task 306 (this was the one I had additional mapping to complete yesterday)

  2. Task 428

  3. Task 150

  4. Task 266

  5. Task 233

The project that I have been working on (Uganda 2022 Ebola Outbreak - Kitumbi Subcounty Kassanda District Project) is now nearing completion with only 3 sub-squares left to map (the remaining tasks are awaiting verification prior to completion)

  1. Task 512 - 35 mins

The last task I helped with Task 511 (25 mins) had a number of areas where I couldn’t distinguish between houses or ground distrubances, so instead I completed as much as I could then submitted the task as uncomplete to allow another mapper to review and contribute.

As the only other remaining tile was locked this is the end of this project for me and I will need to look for a new project to work on next.

Total Time: 1 hour

Getting new users to contribute to collaborative mapping with OpenStreetMap sometimes can be a hard task, and even more difficult when you think about attracting new women users, especially if you are in a country like mine, Brazil.

Why do I speak of new women users? Because if you are in a country like mine, Brazil, most users are men, and this is not the reality in cartography courses, then why women in general aren’t participating, because they do not feel encouraged to participate, is that it?

In this text I will talk a little about my experience for you. Here in the group that I am part of with my college friends, we were having a hard time getting new girls to join the group and trying to understand this reality we met the group Geochicas OSM, a group of Latin America, a collective that came up with the idea of closing the gender gap among those who participate in the collaborative mapping project OpenStreetMap (OSM).

GeoChicasOSM created the project Las calles de las mujeres (The streets of women), collaborative project with the purpose of producing a map of streets named after a woman, with the goal of linking and generating content on OpenStreetMap and Wikipedia about prominent women. Las calles de las mujeres

So we think: How is the reality in Brazil? And from this questioning my group came up with this work for Brazil and we are analyzing the number of streets that are named after women in some Brazilian cities and despite so far realizing that there is a very large disparity, unfortunately, for every public space that honors a woman, there are 4 honoring men .

Even in face of this reality, we continue mapping the streets of our cities and several women have become interested in participating in this dialogue. This way we have concluded that in order to call more girls to join the participative mapping with OSM, we need to map questions that are important to women and while mapping, we discuss with men and women the importance of honoring women in public spaces, how important these spaces are, and even how safe they are for women.

Project: Uganda 2022 Ebola Outbreak - Kitumbi Subcounty Kassanda District Project

First today I reviewed the feedback given on yesterday’s tasks.

The following tasks have been verified by a moderator and are now marked as completed for the project.

  1. Task 69

  2. Task 163

  3. Task 359

Next I read the feedback left on Task 306. It looks like I missed some buildings off this task, which I have now re-reviewed and added in the missing locations, this took 15 minutes. It was nice to recieve feedback from the moderator regarding the updated version. This is helpful as I continue learning.

Good work @[trixabella] Thank you for contributing your time to helping with this project. You are correctly identifying the buildings in the background imagery and drawing them at the correct size and shape. Your tracing of roads is also good. Please keep mapping.RAytoun

I have also completed the following task which are now ready for validation:

  1. Task 233 - 30 mins

  2. Task 428 - 5 mins

  3. Task 429 - 10 mins

Total Time: 1 hour

I’m proud to announce the release of a completely rewritten front end that supports alternative routes, includes the custom model feature, works on mobile devices and has many more features!

Read more and try it out.

GraphHopper Maps user interface

Posted by mapmeld on 27 November 2022 in English (English).

This is the fourth in a series of posts which I’m doing this year inspired by another user’s monthly updates. In the two months since my last update, I visited Palos Verdes (a bit south of Los Angeles) and mapped a few other places remotely.

Also there is a geo-focused Mastodon server; you can find me there: @mapmeld@mapstodon.space

Palos Verdes / Los Angeles

There are a few fancy neighborhoods segmented by dirt paths which are either for utility access, bridle paths, or fire control. For example one road had horse stables on it, and another served as the boundary between two cities. There are a few access points which are barricaded with a reflector or guard rail, but you can still walk onto the path and onward into the next neighborhood. I talked to a resident who said that his car GPS considers these thru-ways, so it’s possible that they were more connected in the past? I would say OSM coverage of these was good but not great (particularly: linking entrances and exits to the road way, or missing shorter paths and alleys).

A local park was named “Los Arboles Rocketship Park” on Google. I visited and confirmed there is an actual sign with Rocketship in the name (based on a sculpture there).

Central Asia research

I’m considering a hiking trip to Tash Rabat, a Silk Road era landmark in Kyrgyzstan. OSM has the dirt road from the highway, and an additional trail north to Баетов which is missing from Google.

I was also looking at locations with Islamic architecture. Turkistan, Kazakhstan has parcel data (labeled building=yes) and then addresses added by Toyota. So that data is on a bit of a journey. A large area in the city center recently got redeveloped into a park, which I updated on the map. Google reviews dispute how often the park is fully open to the public, whether boats are working, etc.

Grand Canyon

After an announcement that the parks service was renaming Indian Garden to Havasupai Gardens, I renamed the area but kept the alt_name tag.

OSMBuildings

My changes to building height (a tower section separate from the base) weren’t showing up on the 3D view provided by OSM Buildings, so I investigated. I think the problem was an existing building relation where the building:levels tag was on the relation level. I had to add and remove a few tags so the building outline and address is consistent but the building:levels is different for the two parts. It looks great now!

Location: Palos Verdes Estates, Los Angeles County, California, United States

Leadership should be shared among people who together have the attributes and skills necessary to facilitate the completion of the task to be initiated. It is the art of motivating a group of people to act toward achieving a common objective. Pista ng Mapa and State of the Maps Asia International Conference 2022 highlighted the importance of using open mapping, open data, and open source in today’s advancement of technology. As stated by the founder and CEO of Thinking Machines, Ms. Stephanie Sy, “Open data unlocks new insights, especially when people can add in more data.” Mapping makes a significant contribution, particularly in emergency response and identifying safe places, mapping sidewalks to make the world a more walkable place. Dr. Nama Raj Budhathoki of Open Mapping Hub-Asia Pacific shares his thoughts on how important mapping is. He stated, “Mapping is vital to measure, monitor, and make decisions in addressing all these challenges (i.e., climate change, governance) because we need to know what is happening and where it is happening.” I was fascinated by the work of Mr. John Louie Fabila in creating 3D animated maps to promote better engagements. It was a great pleasure to participate in such events and be able to meet friends and mentors, not only from the Philippines but also from different countries around Asia, who shared their knowledge and expertise on mapping. This 5-day conference makes me realize things and discover what I want to do after taking a degree. I learned a lot from all the speakers and mentors who shared their knowledge, passion, and love for mapping. I would like to take this opportunity to thank the lead organizers of the event, Mr. Ben Hur Pintor, Ms. Leigh Lunas, Mr. Ron Francisco, Ms. Feye Andal, and Mr. RK Aranas, for choosing me as one of their grantees to be able to participate in this big event. I was overwhelmed by the knowledge I gained, and I hope that this knowledge not only stays with me but is shared with everyone who wants to learn and appreciate the beauty of mapping.

Project: Uganda 2022 Ebola Outbreak - Kitumbi Subcounty Kassanda District Project

Today I spent time working a new project, this aim of this is to map a region following an Ebola Outbreak to provide Health Authorities and MSF to better map the affected areas and ensure adequate provision of resources.

I worked on adding Buildings, Roads, Tracks, Paths & Waterways. Majority of task contained adequate satellite imagery to spot all these details, however I added comments during completion submission on one task where there were some white circular objects showing which could have been huts however the images weren’t conclusive so they weren’t mapped.

I completed the following tasks ready for validation:

  1. Task 150 - 15 mins

  2. Task 184 - 15 mins

  3. Task 163 - 20 mins

  4. Task 69 - 15 mins

  5. Task 359 - 10 mins

  6. Task 266 - 15 mins

  7. Task 306 - 15 mins

  8. Task 398 - 15 mins

I also contributed to the following tasks which require additional input before they are finished:

  1. Task 84 - 5 mins

  2. Task 362 - 5 mins

Total time: 2 hours 10 mins

26 November 2022
The last page in this sequence of diary entries used to be “1800 to current”. It became so large as to become unreasonable, so I have broken it up into two pages: the original first half is now 1800 to 1899, whilst the second (this page) is now “1900 to current”.

Details:– 1900 to current

  • 1900s early
  • 1900
  • 1901
  • 1902
  • 1903
  • 1904
  • 1905
  • 1906
  • 1908
    • Lawrence Bright-designed homes built on Lenton Road: [Barton House (the wiki uses the historical address of ‘1 Huntingdon Drive’)].
    • Lawrence Bright-designed homes built on Huntingdon Drive: [2].
    • Nottingham Corporation Tramways got Parliament approval to replace 3 long-haul horse-trams with electric-tramcars (to Beeston, Arnold and Carlton). The 3 motor-buses obtained in 1906 had proven unreliable, with continual mechanical breakdowns. The last bus ran on 15 June. A replacement horse-tram was put in place whilst the electric infrastructure could be put in place. As the council insisted on twin-tracks that meant some property destruction + road-widening.
  • 1909
  • 1910
    • May 6, 11:45pm: Edward Ⅶ died very suddenly at the end of bouts of severe bronchitis from March, then heart attacks in May. Aged 68, he had been known as a “Playboy Prince” when young. He was the eldest son of Queen Victoria, and spent 59 years as Prince of Wales. Sentiment turned around completely once he ascended to the throne in 1901, but — whilst not his fault — he left one of the greatest constitutional crises (re: the power of the unelected House of Lords) in the balance for his son to resolve after his death.
    • May 6: At the age of 45, George Saxe-Coburg and Gotha became King of the United Kingdom and the British Dominions, and Emperor of India on the death of his father Edward Ⅶ. George was Duke of York, meaning that he was a second son & thus in normal times next in line to the throne after his brother; look at 1936 to see a repetition of this with his own sons. George took the name George Ⅴ on his ascension to the throne.
    • Ernest A Sudbury-designed homes built on Clumber Road East: [3 Westwood House].
  • 1911
    • Aug 18: The constitutionally important Parliament Act was signed into law. It removed the right of the House of Lords to summarily veto financial legislation, changed the Lords veto on other bills to a delay for a max 2 years, and reduced the Parliamentary term from 7 years to 5. This was the beginning of confirming the primacy of the House of Commons over the (unelected) House of Lords and had considerable impact on the next constitutional crisis, which was Home Rule.
       
      The convention at that time was that, whilst the Lords had the right to veto legislation, they kept their hands out of any finance bills. In spite of that convention the Lords opposed the 1909 “People’s Budget”, put forward by the Liberal leader & Prime Minister Asquith but opposed by the Conservative leader Arthur Balfour. The general election of January 1910 was a hung parliament, which left the nationalist Irish Parliamentary Party with it’s thumb on the balance. The Irish wanted Home Rule (which the Lords opposed) and so backed Asquith. The budget passed in April 1910.
       
      Attention now turned to a Parliament Act. There was vigorous opposition from the Lords which blocked all attempts at reform. Events reached November 1910 without resolution, and the Liberals asked the new king to dissolve parliament (which meant a fresh election in December). They also asked the king to swamp the Lords with new peers if necessary to get the measure passed (which was how the 1832 Reform Act got passed). In the end the latter was not necessary, and the veto got removed.
    • John Loverseed-designed homes built on Pelham Crescent: [18].
  • 1912
    • St James Church (parish of The Park, see 1807) was united with that of St John the Baptist (parish of The Marshes, see 1843). This lasted until 1933.
  • 1913
  • 1914
    • July: George Ⅴ calls a meeting of all parties at Buckingham Palace to try to avoid civil war in Ireland due to Asquith having introduced Home Rule legislation into the House of Commons (but not yet passed). The meetings break up after 4 days without settlement, but that is immediately overtaken by international events.
    • Aug 4: Britain declared war on the Triple Entente (soon to be the Central Powers) in what later became known as World War Ⅰ (or: WWⅠ), but which at the time was called the “Great War” & also the “War to end all Wars” (sic).
       
      This particular series of Diary Entries has listed significant dates affecting Nottingham, and has covered 2,000 years. Throughout that time Europe has squabbled & fought amongst itself in every single century. Those squabbles became more & more serious as the years passed & mankind honed it’s tools of war.
       
      At that time, Europe, Scandinavia & the Baltic nations were comprised of a collection of Monarchies, and the Kings/Queens of all those countries essentially were one extended family. In addition to the sympathies/antipathies of race & religion, Europe itself had become two competing blocks, with treaties & alliances to hold each block together:–

      1. The Triple Entente, comprising France, Russia, and Britain.
      2. The Triple Alliance, containing Germany, Austria-Hungary, and Italy.
         
    • This was the count-down to worldwide slaughter:–
      • June 28: Austro-Hungarian heir is assassinated in Serbia by a Bosnian Serb (small spark ignites giant fire).
      • July 28: Austria-Hungary declares war on Serbia; Russia comes to Serbia’s defence.
      • Aug 4: The Triple Entente faces off against the Triple Alliance (although Italy remains neutral).
      • Nov: The Ottoman Empire + Bulgaria (each are Muslim nations) join the Triple Alliance to become the “Central Powers”.
      • 1915 Apr 26: Italy joins the Triple Entente + Serbia to become the “Allies”.
      • 1917 Apr 6: The USA entered the war on the side of the Allies. The British Fleet possessed a technological advantage against their German opposition, so the German Empire innovated with submarines. The methods deployed by those ‘Unterseeboot’’ (U-Boats) meant predation upon non-combatants, and that brought the USA into the war.
    • Goose Fair was cancelled after the outbreak of WW1 on July 28 and did not resume until after cessation on 1918 11 November.
  • 1915
  • 1916
  • 1917
    • Mar 15: Russian Tsar Nicholas Ⅱ abdicates. A Provisional Government is formed, dominated by the nobility. Grassroots community assemblies (called “Soviets”) are formed in reaction to that.
    • Apr 9: The Sealed Train: in the most astonishing act, Germany arranged to inject a virulent virus into Russia. This was Vladimir Lenin, his wife & 30 other Russian citizens in a sealed train, with blackened windows, from Switzerland to Petrograd, Russia via Germany, Sweden & Finland. They boarded the train in Zürich on April 9 & arrived at Finland Station on April 16. Immediately the Bolsheviks (led by Vladimir Lenin) together with multiple other organisations, competed for power.
       
      • An 8 min clip from a documentary by BBC-Russian is here (no subtitles).
      • Extract from the Michael Person book The Sealed Train:
        “Lenin was so crucial to German war policy that the German government would shortly invest more than 40,000,000 gold marks in him — by modern standards hundreds of millions of dollars.”
      • Lenin… The Train (Ben Kingsley as Lenin; Leslie Caron as Nadia), a film on YouTube: [Part 1] [Part 2]
      • The Berlin terminus from Geneva was Potsdam Station. However, Stettin Station (renamed North Station) was the terminal for the line north to Sassnitz, and then the boat to Sweden, so the train made a wide detour around Berlin between the two Terminii. Everyone remained on the train until the last station in Germany (but I’m not certain which of those three it was). The story is that one of the men left the train to obtain a newspaper and, that was the only town in Germany that became Communist.
    • July 17: At a time of heightened anti-German feelings, George Ⅴ changed the name of the British royal house from “House of Saxe-Coburg and Gotha” to “House of Windsor”.
    • Nov 7: The Bolsheviks had gathered a “Red Army” which organised an armed insurrection in Petrograd (now Saint Petersburg, and then the capital) which took power in Russia. Because Russia was still using the Julian Calendar, for them this was the October Revolution. The country now descended into a 6 year Civil War with Red Armies matched against White and all the worst excesses of internecine warfare, and quite a few new ones tossed in there as well. This was also Russia effectively backing out of the “Allies”. The German efforts in April were successful.
    • Nov 8: The Titles Deprivation Act was signed. George Ⅴ had many German relatives with British peerages who had fought on the German side. This law made it possible for those titles to be revoked (enacted 1919). In addition, any Garter Flags within St. George’s Chapel, Windsor Castle of the same relatives were removed.
  • 1918
    • March: Spanish Flu broke out in an Army camp in Kansas, USA, and it is estimated that one-third of the world’s population became infected. Only Spanish newspapers did not suppress these reports (Spain was neutral during WW1). At almost the same time a second pandemic (Sleeping Sickness) was reported worldwide; the numbers of infections were less, but were still in the millions worldwide.
      Personal report: my father was the youngest child in his family (7 brothers, 3 sisters). Uncle Bernard was the next-older brother, and he & my father were inseparable when young. Bernard caught Sleeping Sickness as a young lad. He recovered, but not really, and was unable to ever function normally again.
    • Jul 17: Tsar Nicholas Ⅱ & his wife, children & retainers are murdered at Yekaterinburg. The following year, George Ⅴ arranges for Nicholas’s mother, Marie Feodorovna, and other members of the extended Russian imperial family to be rescued from Crimea by a British warship (but George refused to save his cousin Nicholas).
    • Sep 29: Central Powers begin to collapse; Bulgaria signs an armistice.
    • Oct 31: Ottoman Empire signs an armistice.
    • Nov 3: Austria-Hungary signs an armistice.
    • Nov 9: Kaiser Wilhelm of Germany abdicates.
    • Nov 11: The new German Government signs an armistice, signalling the end of WW1.
    • Inflation was considerable.
    • Chalers Lane / Cowe Lane renamed to Clumber Street & widened by 16′ (4.88m) following a gift of land from Duke of Newcastle. This street is considered to have the highest shopper footfall in Britain.
  • 1919
  • 1920s
    • Old-town slums cleared. Housing stock in the area of The Marshes was reduced to less than two hundred.
    • A Parliament Bill granted powers for motorbus routes outside of the city.
  • 1921
  • 1922
  • 1923
    • After a long period of churn, Nottingham & Beeston Canals were owned by GNR.1862
  • 1924
    • Trent Bridge widened from 40 foot to 80 foot (completed 1926).
  • 1927
  • 1928
  • 1931
  • 1932
  • 1933
    • City boundary extended by addition of Bilborough & Wollaton, parts of Bestwood Park & Colwick, and part of Beeston Urban District.
    • St James Church (parishes of The Park & The Marshes — see 1912) was united with St Peter’s Church, becoming St Peter and St James, St Peters Gate (Grade Ⅰ listed) when St James closed in 1935 (only the streetname remains).
  • 1936
    • Jan 20: George Ⅴ died in his bed at Sandringham House, Norfolk (see also 1952). He was 70 & had gone to his bed 5 days earlier with a cold. He kept drifting in & out of consciousness. Finally his doctor administered two fatal injections.
    • Jan 20: Edward Windsor became the second monarch of his House on the death of his father, and adopted the title Edward Ⅷ (“King of the United Kingdom and the Dominions of the British Empire and Emperor of India”). He was 42, unmarried & had become notorious for very public, sexual affairs with numerous married women.
    • Sept 6: The last tram service (to Arnold) is replaced with motorbuses; all remaining trams are sold off, most to Aberdeen.
    • Dec 10: Edward Ⅷ signed instruments of abdication at Fort Belvedere in the presence of his younger brothers: Prince Albert, Duke of York (next in line for the throne); Prince Henry, Duke of Gloucester; and Prince George, Duke of Kent. He had wanted as king to marry the twice-divorced American Wallis Simpson, but political resistance in the UK & Dominions plus opposition from the Church of England left no other choice than to abdicate. He was king for just 326 days.
    • Dec 11: Albert Windsor becomes “King of the United Kingdom and the Dominions of the British Commonwealth & Emperor of India” following the abdication of his brother Edward. As king he adopts the name George Ⅵ.
  • 1937
    • GNR abandoned the section of the Nottingham Canal from Lenton to Langley Mill.
    • City of Nottingham replaced gas with electric lighting. The Park Estate chose to remain gaslit; that is still it’s state today (220 lamp posts), and may be unique in England.
  • 1938
    • The Park Estate was sold by the 8ᵗʰ Duke to Nuffield Trust, which in turn passed it on to Oxford University Chest. Most of the plots on The Park had been acquired on 99 year leases, and those leaseholds were now coming near their end, which meant falls in property values.

This guide is a translation of my previous diary written in Chinese. The motivation for developing this method is trying to find a way to map vast areas of forests with minimum human effort.

Methodology

The OpenStreetMap data is based on nodes and vector ways. Manual mapping requires a mapper to put nodes on the satellite pictures and connect nodes by mouse clicking, which is a time-consuming process. This guide proposes a software-assisted workflow to ease the mapping process, it includes the following steps.

  1. Raster image acquiring and segmentation
  2. Raster image preparation
  3. Vectorization
  4. Mapping to OSM

Raster image acquiring and segmentation

Software used in this step:

  • JOSM
  • Fiji (Fiji Is Just ImageJ)

Install the JOSM plugin importvec and restart JOSM, Download the map data of the region of interest (ROI), choose a satellite source and download the image. Hide the data layer and take a snapshot of the satellite image on (ROI). Save the snapshot as JPG or PNG file.

Open the snapshot image in Fiji. Turn to the menu: Plugins, Segmentation, Trainable Weka Segmentation. A new Weka window will pop up containing the image. On the right side of the window, there are two preset classes 1 and 2 representing features to be recognized in the image. Create more if needed with create new class button on the left side, and in settings button, you can rename the preset class 1 and 2 to meaningful names to avoid mistakes made by yourself.

Now you can use your mouse left click and hold to draw a curve on the image and click “add to class” button to tag the feature and repeat to create several items. Double-click an item to remove it if you tag it wrong. You don’t have to precisely draw along the edge of the feature, just draw a random curve inside it. When you have collected several items, you can click train classifier in the top-left corner to, well, train the classifier.

When training is finished, the image will be covered with different colors, each representing a feature. You can click toggle overlay to check if the classifier works well to identify the image features. At this step, you can refine the classifier by tagging the wrongly recognized area and train the classifier again until the result satisfy you. You don’t have to push the classifier to perfect because a precise vector requires unlimited control points but JOSM limits 2000 nodes to a way vector, there will be a simplification process to reduce the number of nodes. Now you can click create result and have a colored image.

Raster image preparation

Software used in this step:

  • Fiji (Fiji Is Just ImageJ)

Now you have a classified (not that kind of classified :D) result image, each pixel of the image has a value of 0, 1, or 2, etc. representing its tag. The next step is to pick the area you want to map and remove the others. Go to the menu Image, Adjust, Threshold, in the popped-up dialog window, there are two slide bars, use them to pinpoint the target value, say 0 representing the forest. Click Apply and you will see your colored result image turn to a black-and-white image, and only the forest area is left.

This image usually contains a lot of tiny dots you may want to remove. you can use Process, Binary, Erode several times to remove them and then apply Process, Binary, Dilate several times to recover the edge lost of the survived area. Don’t over-use this as it will turn curves zig-zagged. Make peace with the errors introduced in this process as we are trying our best to minimize human efforts.

And also feel free to use Process, Binary, Fill holes to remove the hollow area in the ROI area, this will save our time in the mapping process by avoiding creating a lot of multipolygon relationships. You can add inner features back with another classified result.

You may also want to remove those areas cut by the edge of the snapshot by clicking Flood Fill Tool button on the Fiji. If the edge-cut areas are connected with the main ROI area, use Process, Binary, Watershed to cut all the area into small pieces, after removing the unwanted area, Process, Binary, Close~ once and all the pieces will be connected again.

Now you can save your image as PNG file, and it is ready for vectorization.

Vectorization

Software used in this step:

  • Inkscape

Import the PNG file to Inkscape, use Path, Trace Bitmap function. Choose the default Brightness cutoff method for Detection Mode, and click apply. Now you will have an area-filled vector image, no more process is needed. Save it as an SVG file.

Mapping to OSM

Software used in this step:

  • JOSM
  • JOSM plugin importvec

Now go back to JOSM, and create a new layer. Believe me, this new layer is crucial because you don’t want to mix the imported multiple areas with the existing map. Open the SVG file to the new layer (If you didn’t install the importvec plugin before you take the snapshot, you will have to find your ROI back). A dialog window will ask you about 1 unit equals how many meters. I don’t know how to calculate (maybe I need to RTFM), just accept the default and use ctrl+alt with mouse left click and drag to scale the imported ways to match it with the satellite image. Then choose the ways containing over 2000 nodes and use Tool, Simplify Way to reduce node numbers. Make adjust until it satisfies you. And don’t forget to jump between different data layers to check if the imported ways are compactable with the existing data, then Merge the layers and final validate and check for errors.

Now you can upload your work and shift-ctrl-r the webpage and enjoy.

PostScript

Fiji and Inkscape are all open-source software,s and their manuals are well-written. Especially for Fiji, you don’t have to worry about its strange old fashion UI as it provides tons of manuals and examples.

This guide is mainly focused on area mapping. But the toolchain introduced here may have the potential to help draw highways, by applying Centerline tracing (autotrace) method in the Inkscape. Anyone who tried this is welcome to share their experiences.

Because sharing is good.

After having had my finds reported on in their online newspaper last week, the Kilkenny People today had a half-page article reporting about my discovery of three crannógs in Co. Cavan. newspaper article

This time, the journalist did a bit of extra research. Last time, when I discovered the two enclosures (as mentioned in this article), they used my press release almost verbatim. It must be newsworthy, if they put extra effort in. I wouldn’t know, I’m biased. :P

I sent them the press release about two weeks ago mentioning OSM as often as possible, because there is still a lot of ignorance in the general public about it. So, I will definitely keep on reaching out to the press every time I discover something, just to hammer the message in about OpenStreetMap.

(I don’t own an armchair, btw. The term just means that I wasn’t out in the field digging and instead worked from my desk. Some say it could be understood pejoratively, but that’s not what I meant by using it. They are also not likely 6000 years old, but we won’t know until dendrochronology is done on the site.)

OsmAnd - https://osmand.net/

The mapping of AEDs in Flanders is of poor quality. These last years I improved and corrected it. Mapping AEDs without mapillary is setting death traps. For this conviction I received insults, stupid comments and proposals. We were a few hundred AEDs away from total coverage. I wanted to update OSM with notes asking for mapillary from the monthly official list. The community did not want this. But that is not all.
When I have mapped an AED perfectly the mutilation begins. They snap it to the wall, they add tags that they cannot explain. They make the mapillary key unusable. By doing so, they make my maintenance work difficult. This is also sad for the few good men who mapped well.

For those who have been following my daily progress on Mastodon, here is the summary.

Data Collection

  • StreetComplete: each quest
  • OsmAnd: each POI
  • Notes: each note
  • SOTM22: each talk
  • droneImages: each image
  • OSMTrace: each trace
  • WikiData: each image for WikiData
  • vespucci: each changeset
  • idEditor: each changeset
  • JOSM: each changeset

First 50 days

Graph shows how often an app was used and what average changes were

During the first 50 days I was mainly doing the challenge remotely, which can seen quite well that a lot of mobile apps are present.

Second 50 days

Graph shows how often an app was used and what average changes were

During the second 50 days I was doing the challenge from home, which can see quite well that JOSM is the main app used.

Total 100 days

Graph shows how often an app was used and what average changes were

On days that I mapped with StreetComplete, I usually also used OsmAnd, and sometimes also vespucci if OsmAnd couldn’t solve the issue.

Most the time I was either mapping with OsmAnd or JOSM. Lots of times, I had a backlog of OsmAnd POIs, which I would deal with on days that I couldn’t actively map.

Graph shows the amount of apps used per day

Towards the last 10 days of the challenge, I became quite lazy, where on one day I just mapped on building on JOSM. Usually I would let the OpenAI run and add a cluster of buildings.

Conclusion

The first 10 days I started off strong and it mellowed out from there. It definitely has become second nature to map daily even if it is adding just one new POI or building.

Lots of times it was last minute mapping like in the last 10min of the day, just making any changes. Just so that the streak doesn’t break.

Future

The challenge will continue for at least another 100 days. Luckily with the game Munich S-Bahn Roulette I am introduced to a new area that is sparsely mapped with StreetComplete. So plenty more areas to go!

General

Vías Agrarias

Me estoy encargando de mapear todas las vías agrarias, caminos o accesos a fincas de Arcones, Segovia. Literalmente no había ninguna mapeada. Me estoy basando entre el PNOA y el Catastro y conocimientos propios porque las ortofotos de la zona ya tienen un tiempo.

Cambio en la etiqueta de los barrios

Los barrios pertenecientes a Arcones estaban indicados como aldeas independientes (place=hamlet). Según la wiki las divisiones de un pueblo (place=village) deben ser indicadas como place=neighbourhood y así lo he hecho con los nodos. Los he añadido a la relación del límite como subarea cada uno.

La Mata y Castillejo

He añadido o corregido edificios que estaban fusionados en uno solo. He añadido diversos muros entre casas y fincas y especificado el uso de la tierra en varios casos añadiendo prados, tierras de cultivo, huertos y zonas de césped.

Arcones

He añadido mobiliario urbano en la Plaza Mayor y detallado algunos edificios públicos con sus nombres. Antes de esto ya añadí una acera imprescindible para poder enrutar a pie y otras no tan necesarias junto con sus cruces de peatones. Aún me falta por especificar en condiciones el ayuntamiento y otros edificios de interés como bares y tiendas.
