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?

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:–
Today, v3.20 of the openstreetmap-carto stylesheet (the default stylesheet on openstreetmap.org) has been released.
- Render aeroway terminal buildings like other buildings
- Removed rendering of landuse=farm
- Added rendering for arts centre, fitness centre, plant nursery, mixed lift aerialways
- Rendering for fens changed
- Typography for point road-related features, addresses, and water features changed
- Removed rendering of waterway=canal as an area
- Take text properties of roads under construction from the type of road they will be

Yes, sorry, it is long overdue to share -- shortly after SotM, I took leave after the birth of my son, and only finding space to pick this up with the upcoming Board Face to Face.
There were many solid ideas, and of course further discussion. Would love to find several avenues to explore these. I think one could be the Advisory Board, which will include representatives from official Local Chapters. For "incubating" local chapters, maybe we discuss ideas on the local chapters mailing list. For communication ideas, we should figure out the right place...
Dorothea took thorough notes from the session. Posting the summary below.
Organising local communities
How OSMF Could Help?
- Add new "tier" to Local Chapters for semi-formal groups not ready to register as a formal organization or full Local Chapter status
- Subsidize some costs of groups in poor communities, including support for accessing internet and computer equipment
For OSMF membership
- 2-level tier for membership fee, to include mappers from poorer countries
- Vetting of members at lower membership fee by local chapter
Other fundraising options for local groups:
- Ask local companies
- Mapathons at places (like bars / coffee shops) which donate percentage of the proceeds
- On membership signup, option to donate additional amounts
- Restart equipment (GPS / phones / laser distance devices) lending program, either from OSMF, or between local communities
- Legal questions on OSM activities in places like Pakistan
- Groups as part of larger organisations
- Organize national level donation collection through non profit associations for tax benefit, then donate to support OSMF
- Central OSM-supplied platform for social aspects, there is fragmentation between communication tools (lists, some people find IRC/forum unappealing, FB, etc) ** The platform should also be helpful for organisation purposes (i.e easy past message retrieval)
- Creation of map that has local groups with contact details on it
- Tickbox on sign-up page to accept push-notifications
- Short video (maybe localised) before the first tutorial in iD, that explains what OSM is all about
- Identifying & contacting new mappers as they join -- Belgium and Switzerland have models
Build tool to contact new mappers. The welcoming message will, ideally ** be personalised ** push people to come into contact with local groups ** let them know options available ** mention local upcoming events ** also, it will be followed-up after a few weeks/month (people have limited time)
Possible revitalisation of Welcome WG
Friendly reminders to decrease duration of mapping inactivity
- Drop-down list with current news (national/regional) on osm.org
OK, a week of Easter special.
More new Pokémon mappers, [edited] and more map data which is quite, err, not that quite above par. Well...
It has been a mighty long time since I documented some Street Art (the last was some Lions in Gedling, Gedling's obsession with stick-men, then in Wollaton Avenue but the main last entry was back in November).
(that variation appears to be positioning them on the street such that motorists get a sporting chance to mow the actual schoolchildren down, and only then are presented with a line of Plaster Children to warn them not to do so) (the school entrance is behind the photographer & in front of these
Next is a house-elf (at his feet are rescued cobbles from a Nottingham street):–
I've just uploaded some changes to this proposed road (I've also made it an associatedStreet Relation so that all the various connecting roads + roundabout(s) can be viewed):–
The map provided from the council shows it passing through the middle of some Retention Lagoons (I certainly hope not - our route misses them).
No GIS is available (that I know of) so I've used a combo of what appears to be a detailed, accurate (but tiny) map & a much larger, and out-of-date, inaccurate map to hand-draw as accurate a route as I can manage.
The planned Gedling Access Road (GAR) is a 3.8km road which will run from Mapperley Plains to the A612 at the Burton Road/Nottingham Road and Trent Valley Way junction.
Planning permission for the road was approved in December 2014. Construction works for the road is due to start in (Spring) 2017 with completion set for (Spring) 2019.
The extension of Magtymguly şaýoly west to the traffic circle on Köşi köçesi has been opened so I collected GPS traces today, tweaked the path of the street under construction, and removed the construction=yes tag. Ann held the iPhone to collect OpenStreetCam data, which allowed us to add bus stops on the new section of street and verify location of traffic lights (stoplights) and intersections. http://www.openstreetmap.org/way/479294344
Yet another first:– the first working farm that I've mapped (other, non-working, farms in Gedling have been Manor Farm Arnold Lane, Glebe Farm Lambley Lane, Phoenix Farm Arnold Lane 1, Phoenix Farm Arnold Lane 2 & Scot Grave Farm Arnold Road). You can find Gedling Wood Farm farmyard & fields here:
The farmer was enormously helpful; she made a photocopy of the field layout for me and named every field. In return I've spent an hour moving the existing landuse=farmland out of the way & have entered the first 6 fields on to the map. I like the way that they are rendered on the standard map; much more subtle than drawing the hedges in.
I've got one difficult decision to make. Ordnance Survey have two “Gedling Wood” on the map, which OSM have duplicated + added a third:–  is to the north & larger;  is invented;  is close to the farmhouse & smaller. The farmer named the field containing the smaller wood as “Little Wood”. I've got a suspicion that the farmer will know the names of the fields & woods better than the OS do, so am tempted to rename it (and remove the invented wood). Still, that is for tomorrow.
This is the farmhouse; it is ever so much older than you think (1600s - she named some feature about the windows as being an example of that period, but I could not retain it; naturally, the farmhouse also has a well):–
I've added all the farmer's names for the fields, and used hers' in preference to the OS duplicated names.
The farmer had an old embroidery on the mantelpiece which, when she gave me the photocopy, I realised was of those fields. It allowed me to realise the powerful sentiment that the family had for their plots. You only need to think about it a little to realise that those fields are the Farm, and are not just their livelihood but also their life.
This is the name of a street in nearby Lambley as well as the northernmost-field on the Gedling Wood Farm. I could not find the name in my Concise Oxford dictionary, but it turns out to be a typical East Midlands word:–
An East Midlands dialect word meaning a wooded valley ... a belt of trees along the bed of a small stream
...which is precisely what happens in this case (an unnamed stream which flows through Burton Joyce & eventually drains into the River Trent).
