Recent diary entries
Since starting mapping in 2015, Batangas City is still developing, and many newer developments have come. Much of the new developments are occurring along Diversion Road and the Batangas Port area. Subdivisions are growing into the suburban and rural barangays. Two new power plants have opened. But, current imagery used for mapping creates a problem to map these new developments. Though Bing announced imagery updates this 2017, it will be a long wait.
Developments to be mapped is shown below, along with description, notes, and status.
- Batangas Health Specialists Medical Center (involved also relocation of some NGCP 69 kV lines due to construction work on part of right-of-way of those subtransmission lines. Polygon and building now mapped, but not the 69 kV line relocation.)
- Batangas City Grand Terminal expansion (adding commercial areas and covered bus terminal. Traffic rerouting mapped, but not the new developments)
- new car dealers along Diversion Road (Suzuki Batangas City, Isuzu Batangas City, Hino Batangas City. Now added)
- San Gabriel and Avion power plants (opened 2016. Still unmapped because imagery still do not show any evidence of those plants, even just their construction.)
- NGCP Batangas Substation (addition of two 150 MVA transformers and 69 kV switchgear to accommodate Meralco's Mahabang Parang - Batangas City 69 kV subtransmission lines and 69 kV power supply for JG Summit in 2015, and relocation of some 69 kV lines in 2017, that replaced some tap connections with connection to a new 69 kV bus in the substation in 2017. Transformer additions, including new bay, are mapped, but not the new switchgear, due to lack of usable imagery from Bing. 69 kV line relocation still not mapped, while thick can be mapped without using any aerial imagery.)
- Camella Solamente (started 2015. Still not mapped due to lack of more recent imagery showing development.)
- Monte Maria Batangas (opening of chapel below statue of the Virgin Mary. Building below the statue already mapped, along with realignment of surrounding road, adding of Meralco 13.2 kV distribution line and restaurant. Needs further update).
- Batangas Port expansion (started 2015/16 and ongoing. Only a few warehouse buildings mapped, but expansion area is mapped)
- SM City Batangas (new side entrance, hallway shops, and restaurants, and relocation of some shops and SM Supermarket. Partially mapped.)
As these developments go around the clock, these are to be placed in priority. Barangay mapping, further land use, woodland and farm mapping, and other local updates, especially around Poblacion, Cuta, Pallocan West, Kumintang Ibaba, Kumintang Ilaya, and Alangilan, are also to be added to the mapping priority list for Batangas City.
Mapping in Batangas City has been increasing after the LGU-led mapping from March to April, yet, it caused some problems in the current data because of mapping practice that looks like tagging for the renderer. Yet, aside from the LGU-led (Batangas City CPDO, CDRMMO, and OCVAS) mapping, there is a new surge of mapping activity in Batangas City. It is part of the MapTVPL activity in Batangas. One among who led the mapping is (GOWin)[https://www.openstreetmap.org/user/GOWin), who mapped Batangas State University, and the surrounding area. Batangas State Univerity's map has improved, with some named streets inside added, buildings named, and new buildings mapped. It is also the same case for the adjacent Batangas National High School (BNHS), whose buildings have been named and more facilities inside mapped, since I started mapping it's buildings, plus mapping during the NOAH-ISAIAH HOT task in Batangas.
It may be expected that the Batangas City LGU may start another mapping project, but should have to avoid problems with existing map data, especially buildings and POI's. The rural barangays have improved, thanks to Batangas City employees contributions, with barangay halls, water supply tanks, schools and day care centers mapped, and a lot more must be expected. Marking the centers of barangays, using the newly added data from Batangas City LGU mapping, are still needed, and further mapping of other missing critical POI's especially schools, as they serve as evacuation centers in times of calamities.
The OpenStreetMap Ottawa community was working on the Ottawa building import that led to an addition of 350K buildings and address points to OpenStreetMap.
This project was completed on the 7th of April with a mapping party hosted by the community, and Mapbox had an opportunity to sponsor this mapping party. As a Mapbox data team member, this was a great opportunity for me to interact with the community and get an understanding of the workflows they follow to make this import happen! The community is currently validating these tasks.
The map showing the buildings added by the community made using Mapbox
It was early morning (5 am) in Bangalore but it was worth waking up to interact with the folks from literally the other end of the world ;). There were nearly 25 attendees for the meetup and it was great to chat with the organisers and get an understanding of the import, and in general the community! Love how different communities work together for making OpenStreetMap the best map of the world! Special thanks to Rps333 for helping us in making this happen!🙇🏼
Members of the OSM Ottawa community at the weekend mapping party to discuss the Ottawa building import and mapping the remaining buildings in the city interacting with the Mapbox data team in India
This area is Tagondaing village
In Ethiopia most of the population lives in rural areas outside of towns and villages. The existing OSM road tagging is inadequate to adequately document the functional use of a road.
The Africa Highway tags are a good start but do not have a tag that is appropriate for rural residential roads.
At the State of the Map Africa 2017 http://sotmafrica.org/ we will be discussing the tagging for roads in an Africa context. #SOTMAfrica
Here is a (virtual) walk through a wood on the north-east periphery of Gedling Village. These woods & meadows are well looked after by local residents, and they try to help, so here is a taster of what you may see during your journey:–
Text (for Translators):–
Beautiful things to see today
Small white wood anemones are in flower in the woods. You can see them as you look among the trees from the bottom path of the woods just above the first meadow (the meadow nearest to Wood Lane).
Overhanging the second meadow, but growing in the woods, is an elm tree which has a lovely shade of light green ‘foliage’. On close inspection you can see that what look to be leaves are in fact clusters of seeds.
The third or top meadow has some cowslips and primroses. These can also be seen in the glade (by the log seat) and at the side of pathways throughout the woods. Notice also purple, mauve and white violets and bright yellow celandines.
The hedgerow includes blackthorn bushes with white flowers. These flowers will eventually form sloes. You cannot make jam or chutneys with sloes, as they are very bitter, but they can be used to flavour gin.
The bluebells are coming into flower and there is a particularly good display in the woodland furthest away from Wood Lane. English bluebells look delicate, have drooping bells and are fragrant. The Spanish bluebells have strong stems, the flowers are more erect and they have no perfume. There are also wood anemones in this area.
Enjoy your walk!
The walk was made at about 3pm on Wednesday, 19 April 2017. Try to imagine sunshine & lots & lots of birdsong. It is only a short walk, really. Here is one of the maps of the location. We shall be walking to the right (maybe later some folks will picture some of the other routes):–
Here is the kissing gate to get into the walk. Click the link below, then either press the start button (
▶) for auto-change (a little quick, maybe?) or keep pressing the right chevron (
>) at top of page and you can pass along the entire walk. Have fun!
Wednesday 26 April 2017:
Here is another, longer, walk that starts near the end of the previous walk and, at first, returns in the reverse direction then turns to the right and continues close to the meadows, eventually returning near to the start of the first walk. There's also a little surprise partway through (3 frames) with a couple of rabbits frolicking on the path (one of them is suicidally bold & remains in view until the last minute, whilst the other shows normal levels of caution):–
Global map of airplanes found "on-the-fly" at OSM background imagery:
*Just zoom max to the plane and click in "open in iD" at left.
You can ad other planes you've found...
On the occasion of World Malaria Day today, lets join to celebrate the successful efforts of mappers worldwide who have traced nearly 1.7 million buildings and 200k Kms of roads into OpenStreetMap that will help health workers eradicate malaria in various developing nations. The visualization of the project created by Mapbox is here. This vast amount of data was added in under 9 months by thousands of volunteer contributors of the Humanitarian OpenStreetMap Team (HOT) in collaboration with Zambia's Ministry of Health, PATH, Tableau foundation, Digital Globe and Clinton Health Access Initiative.
Stats from OSM analytics
The Campaign under Zambia's ministry of health successfully mapped buildings in Zambia. Total 78 projects have been completed regarding Malaria mapping in Zambia.
The elimination Malaria campaign under Clinton health access initiative is still in progress.
The community has been passionate and active in knocking off the tasks by mapping the buildings in Zimbabwe.
Project comparison from Missing maps
We are also working closely with community in mapping buildings in Zimbabwe under Malaria elimination program.
Katelyn and Laura from Clinton health access initiate kindly gave us all the information we needed about the Malaria elimination program. The link for the presentation from them can be found here
How can you contribute?
A lot more projects are going to come under eliminate Malaria program and mappers are welcomed to give their valuable contribution through mapping. You can check the status of the projects here.
Let's join hands to eradicate Malaria through mapping!
After seeing the diary of how to use Mapillary to add building attributes on The state of San Francisco buildingsi decided to create this article on how to use Mapillary as a tool to improve OSM road data. This article will focus on how to use Mapillary traffic sign detection to implement turn restrictions, Mapillary imagery to add lane value and turning lanes. I won’t get into how to capture Mapillary images using smartphone or action cams, as you can find that information on Mapillary website check here and you can request a car or bike mount for your smartphone here
(Please note that from my experience, after uploading the photos to Mapillary, the traffic sign detection can take from 24 to 96 hours to be processed and being displayed on the map).
Editor used JOSM. JOSM plugins needed: Mapillary; RoadSigns; Turnlanes-tagging; Turnrestrictions.
Open JOSM, go to EDIT and then pick PREFERENCES. Once in the options, head to the PLUG-INS menu and search and install these three plug-ins: Mapillary (for being able to use Mapillary imagery and “Mapillary object layer”); RoadSigns (if you want to add the traffic signs to OSM); Turnlanes-tagging (for being able to add turning lanes); Turnrestrictions (to create turn restrictions on intersections).
To make a thematic editing easier, head to VIEW/Map Painting Style and select Map Paint Preferences. Scroll until you find “lane and road attributes” by Martin Vonwald, select it and send it to the right using the arrow and then click ok.
Head back to VIEW/Map Painting Style and select LANE AND ROAD ATTRIBUTES, using this layer will be easier to check the current attributes on the OSM data (notice the number of lanes and lanes direction being displayed).
Pick a location with Mapillary photos that you or others have gathered. Go to IMAGERY and select: Mapillary and Mapillary object layer (the traffic signs will be shown on the map and the green dots are the Mapillary photos, you can turn off the layer if its too much information for you to handle.
Mapillary object layer with the detected traffic signs:
Adding turn restrictions
In this intersection it's mandatory to go straight (notice that the there's a traffic sign on the Mapillary photo layer, which means that a traffic sign was detected in that photo, if you pick that photo on the map (turns it into orange), the photo will be displayed and you can see the sign in the photo.
Lets add the turn restriction to the OSM data (notice, make sure to split the lines in every intersection or when there’s different attributes): First select the “from” line and then press CONTROL key on your keyboard and select the “to” line.
On the TURNRESTRICTION, click on “create a new turn restriction”, a menu will pop up with the road names. In this case pick “Straight Only” and click ok.
Turn off both Mapillary layers and notice a Straight Only sign appears on the Data Layer. Submit the changes to OSM.
Adding speed limits and bumps
Notice the traffic sign with the speed limit of 40 that was detected on the Mapillary object layer.
Lets pick create a node in that line and move the node to where the traffic sign is located and press “P” to split the line. On our right pick “+add” on the tag and enter the “maxspeed” and its value.
Add a bump. Check the detected bump sign by Mapillary.
Create a node in the line where the bump is (notice, bump signs are located 50 meters or less before the actual bump, so make sure to click on “next picture” on the Mapillary photo preview, until you visualize the actual bump).
Go to the menu and go through PRESETS/HIGHWAYS/WAYPOINTS/TRAFFIC CALMING and pick BUMP
The bump has been added, submit changeset to OSM.
Adding turning lanes
Notice the lane turn restrictions detected by Mapillary (left one is mandatory to go left and the right lane turn left or go straight).
Let’s use the Turnlanes plug-in to add the data to OSM. First select the line, then ALT+SHIFT+2 the plug-in menu will pop up. Add the number of lanes, in this case 2, and the mandatory turning lanes (left lane goes left, right lane goes left or straight)
Click ok. Notice how useful the “lane and road attributes” by Martin Vonwald is to visually display the data you just added. Submit changeset to OSM.
Adding traffic signs
Give way sign detected by Mapillary
Create a node in the line, select it, go to PRESENTS/TRAFFIC SIGNS/pick the sign
Menu will pop up, asking the location of the sign and in which direction does it apply.
Apply and notice the traffic sign is now added (you can clearly spot it as it has a white background, which does not occur with the Mapillary object layer that is transparent).
Adding sidewalk information:
By navigating through Mapillary imagery you can add the sidewalk attributes.
Notice on the Mapillary photo that after the intersection, there's only sidewalk on the right side of the way.
Select the line before the intersection and add the a tag with “sidewalk:both”. Select the line after the intersection and add the tag “sidewalk:right”
As you can see with the “lane and road attributes” paint style you are now able to see the sidewalks attributes.
By implementing this workflow, we can assure high quality road data on OSM and the best data for routing.
I advise you if you have a strong local community of mappers to have a similar approach as Chetan did and use a OSM Task Manager to better organize: Collecting Mapillary photos; Adding the data to OSM; Validating.
Similar approach can be used to add street names, house numbers, fire hydrants or POI (like stores, bars, etcetera) if you capture photos on Mapillary with the smartphone pointed to the sideways instead of forward.
If you use OSMand, I recommend you to check how to add Mapillary overlay, so you can calculate your route to capture new sequences of streets that aren’t on Mapillary
Hope it helps, capture photos with Mapillary and improve OSM with them.
[See #1 for “Who stole Willow Brook?”]
Did someone steal a Footpath?
Waterhouse Lane was a recent survey, and I've never seen so many footpaths & Service Roads coming off the top of a road before — makes it look like a tree. The north-south footpath travels eventually to Lambley, is complete, but has to appear on the OSM map in numerous segments due to the mapping constraints (1-6 is within Gedling streets, 6-10 is within fields & 11/12 are within Lambley):–
So the North-South public footpath seems complete.
There is also an East-West public footpath (seen clearly on this NLS Map but make sure that you choose “OS 1900s” as the “Background Map”). The E-W footpath appears on those maps to travel from Lambley Lane & stop at Waterhouse Lane, but an access strip is clearly visible on some maps between the end of the footpath & the bend in Wood Lane.
A resident close to the footpath asked me if I knew anything about a continuation of the footpath as described above. He thought perhaps that it had become sealed off. I had to both profess my ignorance in his case & state that I had seen such an occurrence many times elsewhere.
For the record, these are the segments of the E-W public footpath:–
What I find most interesting is the way that these ancients paths persist down the centuries, and how Waterhouse Lane was far more important to Gedling than it at first appears.
OpenStreetMap diaries are a great way to communicate with the community worldwide. Since past few months, few of us are receiving irrelevant comments on our diary posts from users who mostly have no edits (likely that they are new to OpenStreetMap)
Some examples of such comments are:
- This is a snapshot from a diary post written by me.
- Can there be a way, where we can close the option to comment on a diary post after a particular period?
- Is there a possibility of deleting such comments from the post?
- Is anyone else also facing similar issues?
Yesterday I was walking in Montes de Málaga and I observed a beekeeper working. How to map an apiary in OpenStreetMap? I thought maybe there were no tags for this feature, but I was wrong! There are tags to map apiaries, beehives, expositions and even the beekeeper's house.
My last survey included the best-surfaced
unadopted=yes road that I've yet seen:– Waterhouse Lane. In the course of that survey I discovered:–
- Why Willow Brook was dry
- Yet another (possibly) stolen footpath
Who stole Willow Brook?
One of the residents on Waterhouse Lane told me that it was so-called due to a Water Pump that originally existed in that lane. Today, that Pump has gone. An old OS map shows a stream falling north to south, eventually along this lane, and finally emptying into Ouse Dyke. Only a bit of that old riverbed remains, and it is dry.
A very kind lady at 11 Waterhouse let me take a photo of the stream from the bottom of her garden (from the opposite bank to the school), but her plot does NOT include the stream. This is shot over the top of her fence; the stream is supposed to run right-to-left, and the stream-bed is at the base of the tree in the centre of this photo:–
That is NOT a very useful photo & I was having lots of difficulty finding this stream. Some residents told me stories of them or others culverting (parts of) the stream, but that did not answer where the greater part of Willow Brook had gone to. There was also a small — if remote — possibility that it might affect the soon-to-be-built Gedling Access Road (streams rarely just ‘go away’).
Severn Trent Water normally readily answers my queries across the telephone, but this time I was passed around then asked to send an email (to get rid of me). This is the mail that I sent:–
To: Asset Protection Department, STW
Subject: Status of "Willow Brook" Stream + Culverts?
Date: 17:16 24 April 2017
My name is Alex Kemp, and I spend large parts of my time entering homes, etc. into OpenStreetMap (OSM). I'm trying to find the source (and possible culverts) for Willow Brook. There is a (remote) possibility that this search may have some impact upon the Gedling Access Road.
- Tel: +44 (0) 115 987 6543 (number munged)
- Web: osm.org/user/alexkemp
My current survey area is Waterhouse Lane, Gedling, Notts.. A stream is shown on the modern Ordnance Survey map running down part of that lane, beside the Willow Farm Primary School fence (east side). What remains of the stream bed is dry; land-owners upstream appear to have culverted that part of the stream which runs through their property. At the far southern end it runs through a culvert below the (now abandoned) mineral railway line and then into Ouse Dyke.
What is stated above is the part of this story that I know. These are location references to help you to find it:-
- 462211,342685 (drawn from Adopted Highways register: geoserver.nottinghamcity.gov.uk/streetregister/)
- NG4 4BP
- osm.org/way/291378022 (OSM link for Waterhouse Lane)
- osm.org/way/488483839 (OSM link for culverted part of stream)
I'm trying to find the source for this stream (which I'm calling 'Willow Brook').
I can find zero references for culverts to this stream north of it's current position, yet old OS maps clearly show the stream coming down from the north end of the old Gedling Wood, close to the modern Dumble that feeds a stream to Burton Joyce, and to the farmer's field called 'two-ponds':-
- http://maps.nls.uk/geo/find/#zoom=15&lat=52.9804&lon=-1.0734&layers=6&b=6&point=0,0 (make sure 'background map' == 'OS 1920s')
- osm.org/way/486960082 (Crock Dumble - feeds Burton Joyce stream)
- osm.org/way/486960089 (Two Ponds)
The modern footpath and hedges follow that old stream path, as does the geology. The Gedling Access Road is going to cut it all in half.
That footpath (from Lambley) passes almost exactly north-south & travels half it's length through fields & the other half through modern streets & modern Public Footpaths to reach the top of Waterhouse Lane. My assumption is that the old stream did exactly the same, and maybe was the source for the Water Pump that gave the lane it's name.
Is the northern half of this stream culverted, and where does that terminate? If not, what changes made the stream disappear?
Footbridge Across Willow Brook
Wednesday 26 April: The chap at 21 Waterhouse Lane was most kind & allowed me to photograph the footbridge across the stream:–
He pointed out that his neighbour upstream (which rather confusingly is #33) has the brook culverted, so the stream-flow is very low. However, there was some water on the streambed, which was gratifying.
The footbridge was far more substantial than I expected, and there is even a gate at the far end (padlocked) (it is the school playing field on the other side), which suggests that there may have been a public footpath through that location in the distant past.
See #2 for “Did someone steal a Footpath?”
First, I would like to congratulate the YouthMappers at AUW for wining the HOT micro-grant award with other seven communities globally. I would also appreciate other micro communities and chapters for competing the micro grant program and wish you luck for the next one. I would like to congratulate YouthMappers DhakaCollege, YouthMappers at AUW for wining 2017 chapter award, Maliha Mohiuddin from OpenStreetMap Dhaka University for wining best blog award 2017 and also other three chapter members for wining the leadership award and going to participate in workshop to be held in Nepal.
Let me give you some upcoming mapping programs that are under discussion but hoping to be launched soon:
There will be a series of mapathons for mapping the existing features of 13 coastal districts of Bangladesh what we want to organize in a different manner. We will call for application/proposal from chapters, micro-communities, universities who wants to hold the mapathon/s at their premises. The selected will have the required training, logistics, appreciation certificate. I shall call for the application within a month or two.
BDRCS Volunteers are going to be engaged soon for community level training and mapping. We are planning to expand the mapping of vulnerable buildings for urban resilience where the city ward emergency response committee members will be taught how to and map their respective wards. In near future we want to replicate for disaster vulnerable districts too.
To find and enhance more use cases of existing OSM data in Bangladesh we would like to call for participation of a research teams, person/s in a research grant program . The selected teams or persons have to come up with scoping ideas showing result of spatial analysis, vulnerability assessment, risk analysis, scenario modeling or future projections. I will invite the potential universities and also open call for other researcher or team when we are ready.
I want to map the Nijhum Dwip - নিঝুম দ্বীপ, one of the most vulnerable island in Bangladesh where loss of lives and livelihoods are common matter due to cyclone and storm surge. I would request some volunteers to assist me in field level data collection and mapping in next month.
Finally, I am very happy that more and more service delivery and routing startups are using OepnStreetMap for their application. NerdCats team is going to update their Bus rout app based on openstreetmap after their famous and successful app GO! Traffic Updates (by GObd.co). Pathao service wants to use and update the roads of whole Dhaka city, for that they are going to organize a mapathon in 29th of this month jointly with OpenStreetMap Bangladesh community. I am requesting all the members of our community to join this mapathon and help Pathao to make a better and detail dhaka map.
Thanks. I wish you all the best in coming days. Happy new Bangla Year 1424.
Anyone from New Paltz NY use this platform?
Spent a bunch of time cleaning up the OSM data for Blarney, Co. Cork. Few other OSM participants joined in too which was fun.
This is not exactly my best photo ever, but the chap that I woke in the middle of the day with my knock on his door was a shift-worker (speaking to me naked from his cottage bedroom window) & I really did not want to disturb him any further, so fled without a better one (the pump handle is on the unseen side; the pump stands at the centre-boundary of two semi-detached cottages):–
Before the industrial era every British town street (and many individual houses) had their own hand-operated pump for obtaining fresh water. One of my favourite stories concerns the 1854 Broad Street Pump, in which Dr. John Snow used for the first time epidemiological mapping of cholera outbreaks to conclusively prove that the Water Pump on Broad Street (at what today is the intersection of Broadwick Street & Lexington Street) in Soho, London was solely responsible for local outbreaks; at the same time, his research proved that water was the medium of infection rather than miasma.
One incidental extra to the Broad Street Pump story is that the 19th Century cholera infections which are so often spoken of as London outbreaks were in fact nation-wide — the St Mary's Churchyard where Bendigo was buried was originally established due to the 1832 outbreak. Cholera at that time produced such a flood of dead bodies that a new churchyard was required to cope with them.
I've always been vaguely aware that individual branches within retail chains come with numbers. For example, my company's business partners routinely refer to their branches as numbers, instead of locations: "Call five and ask how many of X they've got in stock". Or: "Get me last month's stats from three, eight and twelve".
It wasn't until a few days ago that I read a petrol station receipt I got (it said Petrol company so-and-so, branch 34) and it dawned on me that these numbers can be collected and entered into OSM using the "ref" tag. I'm not quite sure how exactly this can be useful to anyone but I do know for sure that people who work with data usually like their data numbered. So from now on, I'm shopping at 017, filling up my car at 34 and hunting for more receipts.
Joined OSM community. Main goal to do small things to improve Helsinki Region Transport's (HSL) route planner Reittiopas.fi Live in Ruoholahti area so started with small steps by naming some buildings etc. in the neighborhood.
(my problem is not in starting, it is in stopping)
- Q: When is a stream not a stream
- A1: When it is dry
- A2: When it goes underground
I got to Willow Farm Primary School & it should have been closed due to Easter, but the school gates were open. My good fortune, because the School Caretaker lives in the bungalow near the entrance & came to check me out. After a little conversation he took me to see the stream that ran alongside the school, travels in a culvert beneath the abandoned high-level mineral railway then empties into Ouse Dyke.
This is the stream on the other side of the metal fence but look carefully - there was no water in the stream when I took this photo:–
