Access to financial services through banks, ATMs, microfinance institutions and via mobile money is a key driver of poverty reduction and financial empowerment, especially for women who have traditionally been excluded from such services.

These services still do not yet reach everyone. Working on the ground in Kampala, HOT is partnering with Financial Sector Deepening (FSD) Uganda, community members, and students from Makerere University to teach community mapping skills and then map banks, atms, and mobile money services, along with schools and health sites.

Community-led mapping will serve as a starting point to building maintainable, high-quality map products that are open to all while being verified and kept up-to-date by local communities. In the short term, the program will contribute to building a highly-functional local infrastructure and community capacity for mapping. It also makes open financial service provider, health site and school data available in multiple free, accessible formats via OpenStreetMap, with the goal of helping service providers to increase coverage and access.

This Tasking Manager Project will directly help the Kampala community mappers by "pre-mapping" basic road and building data that will then be updated, completed and added to by the local project team and community from January - April 2016.

When saving your work, please leave the default comment but add what you actually mapped, for example "added buildings and a residential road".

Project Specific Mapping Notes

  • Many of these squares will already be partially or fully mapped, map in more if needed or fix up the existing mapping, or just mark it "Done" if it is already complete.
  • Please connect up roads that are not connected to the main network or nearby roads.
  • Please disconnect roads that are attached to landuse=residential areas and draw them into the settlements and connect them to other roads that enter the settlements
  • Waterways are challenging in this area, more need to be mapped, but please only map the streams and rivers
  • Many of the buildings are round huts. In the iD editor draw a 3 pointed triangle the size of the hut, then select it, hit the 'o' key and it will turn round. Tag it a building and then you can copy/paste it to other huts of the same size quickly.
  • A 5 minute video that uses iD to edit most of the above points for this mapping project

Roads and Paths

  • Please map roads and major paths as completely as possible by connecting them to the main road networks where ever possible.
  • Very short segments that do not connect to anything should not be mapped.
  • Short segments of a road or path that you cannot see through the trees but seem very likely to exist should be mapped to keep the road complete
  • Try and map a little beyond your task square so the person who maps the task square next to yours can easily connect them.
  • Always connect roads to other roads where they meet and never end roads on Residential area polygon edges.

You will most often use the following road classifications:

  • highway=unclassified - This is for roads that a vehicle with 4 wheels could travel on that connect small villages and settlements
  • highway=track - This is for roads that a 4 wheel vehicle or farm tractor could travel on and only lead to farm fields or forests. They do not connect settlements.
  • highway=path - This is for small paths that a 4 wheeled vehicle could not travel on and are usually used by people on foot or 2 wheeled vehicles. They may or may not connect settlements or lead to farm fields. Only map the major paths that connect to settlements or other roads.


  • Please accurately outline all the buildings you can find. The outline should be for the full size of the building even if it is partly covered by trees in the imagery.
  • After drawing the outline, use the 's' key in the web editor to "square" the corners.
  • Many buildings are very close, but do not actually touch each other, try to map them close to each other without letting them connect or share nodes with each other, roads or residential area outlines.
  • In the iD web editor, the first time you map a building you will use the "Building" category and then at the bottom of the list select "Building" again, this is the most generic building tag we can use as we almost never can tell the more specific use of any building from imagery alone.

General Mapping Notes

  • Be as precise as possible - This takes a little bit of practice, but following a road closely or the outline of a building carefully really makes a difference in the quality of map data produced. Quality is more important than quantity when it comes to mapping. Zooming in close helps.
  • It is ok to "split" task squares - Sometimes a task square will have a lot detailed settlement mapping. If you think it would help to make the task square smaller so the mapping could be finished in a more reasonable time, use the "split" link above the task square comment box.
  • Personal knowledge - If you have local knowledge, that is incredibly valuable and any information you are 100% sure of you can add to the object you are mapping. Building names, health facilities, names of roads, etc, are all very valuable and the name= tag can be used to supply that information.
  • Sometimes a task square is already mapped - Sometimes you will find a task square that looks totally mapped or has nothing in it to map. Just double check that it is complete, map anything that was missed, straighten up anything that needs it and then mark it "Done".
  • Invalidated task squares - You might get a notice that a task square was "invalidated" that almost always just means someone found a few more things to map and they did not have time to map them in. No worries, it is part of the process and happens all the time. If you have to stop mapping before you have mapped everything use the "Unlock" link instead of "Done" As long as you are trying to map everything in a task square you feel confident mapping before you mark one "Done" then all is good.
  • Ask questions - if you have questions, please ask. The front page of this HOT Tasking Manager website offers a few ways to ask or if you are at a mapping event, raise your hand and ask.
  • You are making a real difference mapping - Every contribution matters in a real, tangible way. Mapping in not easy but know that your mapping is used by humanitarian organizations around the world every single day.


The OSM Wiki is where you can find detailed information on how to tag objects, below are some of the most relevant pages to typical humanitarian mapping projects.
