Now, you may go into the OSM-Data world and visit places 'together with a friend'. As you move around, you will see your company next to you, also moving and watching. If you just start “OSM go”, your user name will be the name of your country. Or call www.osmgo.org?user=myName. Use a nickname or even better, use your OSM-name. A 2nd-click any place you want to visit and select the icon of “OSM go” to enter. Your friend may follwow you, using the slippy map (see below).
There is a 'chat' implemented in “OSM go”! Press key C and enter text in the popup dialog. The actual chat texts will be shown in the text box at the top left. There you will also see if an other user is dropping in or leaving. If you like to test it with me (-karlos-) just send me a time, I may be there and guide you. So don’t be afraid if you use “OSM go” and see a moving smile. Some visitors and me had already a lot of fun doing this. Some user of “OSM go” may have been shocking surprised, sorry.
Usually, you will see the OSM default world map with additional layers:
- A number of city icons, you may mostly know as 'Demo areas' from the wiki page Simple 3D buildings. A klick at one of them will show the map menu. There you may select none of the existing 3D renders. The arrow at right will zoom in to the place or zoom out to the world map.
There are the usual map zoom controls, a search control to find a place on earth by text and a control to zoom to your actual location. The cursor keys, mouse- or touch-drag will slip the map. The keys plus/minus and the mouse weel will zoom. A double-click/-touch will zoom in, a single-click/-touch will zoom out. A 2nd-mouse-click at any place or a long touch will popup the map menu as descripted above.
With the menu top right you may activate some “OSM go” specific layers:
“OSM go” shows all users as an icon. Active users will be shown as a smily. A klick on one will show the map menu. If you zoom in by the arrow, you may even see the user move its actual position across the map. If you enter “OSM go” yourselves now, you will arrive next to your OSM-friend. If a user starts “OSM go" or gets passive, you will get an message by the map.
Layer “You” will get active, if you klick on the “location” control at bottom left. Your browser will ask you to use your actual location, show an icon and will zoom in to it. Also the location, determined by your IP address will be shown.
“Visits” will show a lot of red cycles: Places, other users did visit recently. Form the very last visit, the home of the visitor is shown in blue. Of course, a click on a cycle will bring the map menu to start a 3D renderer.
If you visit the map with an given user name (by adding ?user=myName to the URL) only the layers “OSM go” and “Visits” are active.
The map code/function isn’t final. It would be nice, if someone will help me using Leaflet accurate. Like: how to use the enter key for text search. As avatar I used an creepy human eye first, then a glass eye. There should be a way to select or even download an individual avatar, like the eye of 2001-HAL or whatever. ** 'OSM go' uses a lot of URL parameter. I would like to replace them by a map menu, but I don’t know how to do it - yet.
- There is a lot of gaps to fill, like more roof shapes.
- There should be a 3rd person view with an avatar like in “Pokemon GO”.
- The primary intention, to make a “game” to help OSM is still present. In the last days, I played Pokemon to get inspirations. May be: Find new shops or changed places, take pictures to enable arm chair editing the tags of the places.
- I consider to recode “OSM go” in C++ (or Shift ) to have native applications - and use WebAssembly to run it in browsers.

Thanks to members of brazilian OSM community for many tips, specially to brazilian OSM contributor http://www.openstreetmap.org/user/cassioeskelsen for helping when I was struggling with parameters, he works with and knows a lot of GIS.

Keeping up-to-date, relevant maps, is a challenge for many organizations, especially if they don't have the in-house capacity, or the resources to systematically maintain geo-spatial datasets that are useful across multiple departments or end-users. This is not an uncommon scenario in many municipal governments in the Philippines.
Over the last several months, the MapAm❤re Initiative in San Juan, have been collaborating with local actors and promoting Free software, especially OpenStreetMap, to communities who are seeking to make the most of what's possible with Open data.
Last Monday, we've successfully concluded a City Mapa-thon for DRR to help the local government, in particular the City Disaster Risk Reduction Management Office in creating and updating the map features necessary for their risk reduction and resiliency programs.
87% of the people who registered for the mapa-thon made it to event. Thank you to everyone who chose to spend their Monday afternoon with us, helping out the city of San Juan.
Thank you, too to the City DRRMO, for hosting the event and making their facilities available for the volunteers.
A big thank you to our generous benefactors who sponsored the pizza and drinks. And a shout-out to Mapillary, for the swags we raffled after the mapa-thon. Maraming salamat!

The mapa-thon achieved partial completion of the update/identification of barangay-level DRR facilities (mostly in the first district, prioritized because of population density). The mapa-thon participants were mostly newcomers and beginners to OSM editing, and we invested a significant part of the activity to training them how to use the iD editor. Meanwhile, and apart from coaching the learners, the advance mappers also took part in fixing https://github.com/OSMPH/papercut_fix/issues/13.
We also made use of the photos we captured during our Mapillary run early last month. It was a useful reference for mappers during validation, and when trying to determine location or features.
Mapa-thon Part Deux?
We've proposed a possible follow-up mapa-thon on 10th June, hopefully with the same group (to recoup our training investment) before the new school term starts and finally finish working on the remaining barangays. See: https://github.com/mapamore/events/issues/7

The training segment is often mentioned as the least enjoyable portion of the activity, but is a necessary :imp:. We can only strive to make it less boring, and more engaging. It's proper training that makes it possible to avoid things like the screen grab below from happening in the first place, but then there's Murphy's Law. So experienced mappers also play a very important role in validation to ensure quality edits, and in coaching, to show them the ropes.

With Open data, other applications can add value to the data that mappers contribute and with the OpenStreetMap database acting as the primary repository of the same data. Update once, and make the updates available for everyone else.
The map data may be used off-line, on mobile devices. This OsmAnd screen shot shows the same area, with fire hydrants shown. Useful for fire fighters and emergency responders.
This Umap shows city hydrants that is retrieved dynamically from the OpenStreetMap database. Orange dots represent high-pressure hdyrants.
I took a few photos, and shared them here.

I've created a map legend for the map style that I use. It's a set of map data that can be appended to a rendering database to create a map legend in a blank bit of map (actually in the middle of Australia).
There are currently two parts - linear features and POIs. As far as the map is concerned these are "real POIs" (though they're never added to OSM itself of course - just added to the rendering database) so you need to zoom in to see some of the POIs such as the one for vending machines, which only appears in this map style from zoom level 19. You could use it with other map styles, but some of the features are dependent on this lua script.
Here's a preview of what the "roads" part of the legend looks like:
but to use it properly follow the link and move around.
Don't misunderstand me; I like civilisation, I really do. I like that my grand-daughter Micaela can walk down the street without needing to actively fear every man that walks past, or worry about being pounced on by a sabre-toothed tiger, or a cave-lion. There are just so many benefits, like amoeba-free water plumbed direct into the home, lots of shops with shelves full of food good to eat, and maps of the area freely available. It's all excellent stuff, even if it's just the Matrix.
So why do I miss wild woods? With wolves, and deer running free? Possibly it is the Austrian blood from my mother calling to me, or perhaps because I have finally reached the edge of Nottingham's suburban housing (Spring Lane), but at my last mapping session I was able to stand within Gedling Country Park and gaze from the high sierra south across a vista of naturally-seeded trees (please forgive my whimsy) and gain a hint of what the long-gone Sherwood Forest might have looked like:–
However, make the most of it, for the Gedling Access Road (GAR) is coming (GAR Diary), and many of those trees are lambs awaiting the slaughter so that tomorrow's civilisation can embed itself yet more firmly into today. That brown scar beyond the trees in the photograph below is land being made ready for the Arnold Lane interchange with the GAR:–
The developers have agreed 2 years to complete the GAR, starting spring 2017. Apart from a couple of decades of development blight, nothing has been seen until this work on the interchange.
I reached this part of Nottingham in my mapping schedule two weeks ago & realised that the whole area was due for dramatic change very soon. There were a couple of things that I wanted to photograph before they were gone, and gave myself yesterday (Sunday 28 May) to do it.
1. Chase Farm + Cottage
Chase Farm is possibly named for being built within Thorneywood Chase (originally owned by the King & stocked with red & fallow deer, and thus the area had a history of hunts, horses & dogs + poachers such as Robin Hood). It is one of the two farms that has been blighted by the GAR (Glebe Farm is the other). Unlike Glebe Farm, which still has horses in the eastern fields & an energetic lady that visits them, Chase Farm has been entirely deserted, as has all the fields that it once farmed. The access track for the farm ran from Mapperley Plains; the council has had to block that track due to fly-tipping at the farm. Both farm & cottage are now sad sights:–
2. Mapperley Tunnel
The Pepperpots' tunnel approach lay deep within a gorge of trees, with the former track-bed up to 20 feet (7m) below the top of the cutting. If you decide to explore it yourself then be warned that, once off the official tracks, there are zero fences to prevent a precipitous fall to the floor. Also, do not be a fool like myself & wear light-coloured trousers & street-shoes; Clarks are comfortable shoes & remind me fondly of Street in Somerset, but are mostly useless for exploring muddy forests (if it has been raining recently then probably best not to bother, as the access is down steeply-pitched slopes; you may get down but not back up).
Until I surveyed it I did not realise that there are two cuttings that run parallel to each other. The first I followed is to the north & seems to lead to a blank, dead-end. The second cutting to the south leads to the tunnel entrance, and most dark & spooky it was. There is already an exploration into the tunnel available on the internet (and Wikipedia), but I only went 10 foot inside at the most!
I have started to creating polygons and correcting road system/POIs in Pánd, Hungary. Pánd is a midsize village with a population of around 2000 people. I have got local knowledge in this area therefore I decided to perfect OSM here.
Keep on updating openstreetmap guys. It is getting better and better. #makeopenstreetmapgreatagain
Doing more TIGER verification, today. Changing the name "Ducks Head" to "Duck's Head Road" So I am wondering why they have chosen such a strange name as I look at the map and see the referenced duck in the map.
What's happened to maps.me app? I used to be able to add details to existing POI and now I just get "claim this business" which errors.
Obviously some attempt to better commercialise the app but massive shame for the OSM community.
Other apps to check out are Street Complete and (when it launches) the new Kory app.
Last week on the margins of the Turkmenistan Gas Congress held in Awaza I did some update mapping of the the Awaza resort zone, with extensive use of Mapillary to capture imagery. Since the zone is now off-limits to private automobiles it was a rare opportunity to capture bus stops, new hotels and facilities, and generally to upgrade the map. I also added several names of streets in downtown Turkmenbashy and edited the existing street names extensively to bring them into conformance with what is actually on street signs. Russian main name entries are now name:ru=* entries. I added two cemeteries, some street addresses, and edited a couple of streets based on GPS traces. The new expanded seaport, under construction by Gap Inşaat and due to be completed next year, has changed the coastline so I need to review recent satellite imagery and update that as well.
This weekend I added POIs to the new village of Bereketli Zaman, including the fire station and mosque, then added interpolation=* ways so the village should now be largely navigable by house number. It is a strictly cookie-cutter layout so deviation of the mapped house numbers from reality should be minimal.
OpenStreetMap allows people to add notes to the map, people can comment and mark a problem as resolved. This is an easy way for mappers to talk to each other ("Is this mapped right?" "Yes I was there the other month, the aerial imgaery is old" "OK So"), and is an easy way for non-OSM people to provide simple feedback without needing to log in, and (importantly) not break the map if they don't know what they are doing. Experienced mappers can use them to highlight areas or issues they think should be addressed.
There are now more than 1,000,000 notes in OSM. There was some discussion on the OSM main mailing list about this. Some people don't like how easy it is for some apps (Maps.me) to add notes, and complain about the amount of useless notes. Yes, a high signal to noise ratio can make things hard. However OSM is open and a wiki map. There shouldn't be barriers and gatekeepers. If you want only "approved" people to be able to add data to your map, go play with Google Map Maker.
The concern about signal to noise ratios is valid. There are a lot of notes now. About 250,000 open notes. (check on pascal neis' notes page).
So I'm going to make an effort to look at notes and try to fix up problems. Some cannot be solved from the armchair, but there are lots of new users leaving notes that can be closed, or which describe things which have since been mapped. And some are things you could map. I'm going to work my way through some of the notes in Ireland.
If we all take a few minutes each day to look at notes that people are submitting, we'll keep the map updated and fixed up.
Resuming from previous diary posts, we would like to start off with interesting changesets we have observed over the last month. Nearly all of these changesets have been flagged by currently existing filters in OSMCha.
Here is what we found
We found a changeset which consisted of fictional edits that were basically some names and random characters. This was flagged through feature overlap filter. Feature overlap filter takes a feature and downloads nearby features to check if there is an overlap. We have been testing this filter with thresholds of overlap. Code for this can be found here.
We noticed suspicious edits in Japan by a new user, who is adding random parks, waterbodies, footways etc. This was detected by Park added by new user , Waterbody added by new user, and Footway added by new user filters in OSMCha.
If you are interested in getting into details of Pokemon specific edit detection, you can refer to the previous diary post for better understanding.
This is a very small subset of issues we have reviewed. Rarely do we find these kind of intentional errors on the map. We also have come across some detailed mapping activity. One of those is this changeset which added some beautiful details to a castle in Ludwigsburg. ✨
Look forward to more such validation scoops from us. Let us know if you have feedback on any of these OSMCha filters. It would be great to hear similar stories of inconsistent or detailed mapping activity that you have come across. Comment on this diary post and share them with us (We ❤️ screenshots).
I have a program ,and want to make a map to show my staff's route. I copyed codes from the website of https://wiki.openstreetmap.org/wiki/OpenLayers_Simple_Example , but these codes doesn't work . I ask for help ,which online file can I read to solve my problem or can you give me some example？ Thanks for your help.
I stumbled upon OpenStreetMap (OSM) recently. At first I was overwhelmed to see the amount of community work that is put together and reflects in the maps that are created. I was also excited to know how a hobby project of a person now resonates into something that has become a huge success. I started off my OSM project by mapping my hometown Kolar Gold Fields.
Kolar Gold Fields often acronymed as KGF is a small town located in Karnataka, It was once famous for the gold mining which eventually stopped in the year 2001 due to receding deposits. KGF is often compared to England due to its climate and the beautiful landscapes. hence known as “The Little England “
With some initial analysis of the place on OSM I noticed that it was fairly less mapped than most parts of the country . I was pleasantly surprised to notice major parts of the town were already mapped by a community member. This fills me with great enthusiasm to become a more active Community member myself and improve my hometown map.
Before mapping on OSM
what I worked on
Initially it took me time understanding the interface , tools and the shortcuts on OSM . I arrived to conclusion to map my home town as it had very little data.
For a start I concentrated on the road features , Mainly the residential and the secondary road as there were missing. Data was added using Bing imagery as primary source. With time I enabled myself adding buildings , leisure parks , natural lakes, banks and schools, also tagging each feature suitably.
After the edits were made
My local knowledge of the place enabled me identify these features on the imagery and name them. The major strength of OSM can be attributed to its nature. Being an open source and a strong community driven project it enables us to create maps with such intricate details .

This is 5 of 30 users, suggesting that 16.7% (1 in every 6) of users sign up purely for the purpose of spamming OSM. After an analysis of those 30 users shown on my Profile, I found that 80% made no or very little contribution (3 or less edits) to OSM; this seems to be the classic 20%/80% split, and makes it very difficult to understand why all these redundant users should be retained.
Hi! I’m Pedro Amaro, an undergraduate student from Portugal. Currently, I’m studying Informatics and Computing Engineering at FEUP (Faculty of Engineering of the University of Porto). I will be working on a project for the OSM community for Google Summer of Code 2017. I took a special interest in OSM for my GSoC proposal, as I had used it before multiple times, mostly to know my bearings and also in the FlightGear flight simulator.
One of the most interesting suggested projects, that mixed some of my interests, including 3D graphics and web applications, was the implementation of a 3D Model Repository. This project consists of implementing a repository for 3D models, where users can upload freely licensed models and their metadata to it, so that 3D visualizers can use this data to render beautiful graphics for buildings (such as the Eiffel Tower) or smaller features such as trees. After a lot of back and forth with the project proposal with Tordanik, I submitted it, and around a month later, was accepted.
In my proposal, I had suggested using OpenLayers as the API for drawing maps in the repository, and having the live 3D preview of models be optional. Upon further discussion, we decided to change the API to Leaflet and start working on the preview early in the summer, by June.
To explore both ideas, I built a small demonstration of each, to get acquainted with the tools I will be using, namely Leaflet and Three.js.
Leaflet API demo
Three.js OpenCOLLADA demo
The Eiffel Tower model was made in Sketch Up by joe89v, and exported as an OpenCOLLADA model. The model can be found here.
Today, v3.3.1 of the openstreetmap-carto stylesheet (the default stylesheet on openstreetmap.org) has been released.
This version includes a single change: * Fix a regression in intermittent waterways
For a full list of commits, see https://github.com/gravitystorm/openstreetmap-carto/compare/v3.3.0...v3.3.1
As always, we welcome any bug reports at https://github.com/gravitystorm/openstreetmap-carto/issues.
Last weekend, I tried modelling San Francisco City Hall in S3DB. The public building has 100 years of glorious history. The diameter of the central dome is around 34 m and total height of the building is 93 m. From Wikipedia
The co-ordinates of the building is 37.77910°N/122.41937°W. Edited this model first through OSM Sandbox and copied all the geometries and tags to main OSM database. I used JOSM current version and Kendzi3D plugin to visualise locally.
