New Swaziland Malaria Elimination Project 1393

The southern African Kingdom of Swaziland is leading the way in the global fight against malaria and is on the verge of making history by eliminating malaria from its borders.

Swaziland is poised to totally eliminate malaria inside its borders by the end of 2016, according to the Kingdom of Swaziland National Malaria Control Programme. If the country achieves malaria elimination, it will be the first country in southern Africa to achieve zero local cases. Swaziland’s malaria cases decreased by 99 percent between 2000 and 2014 due to the Kingdom's comprehensive malaria elimination efforts which are considered a model of best practices for malaria control and elimination.

The Malaria Elimination Initiative within the Global Health Group at the University of California, San Francisco (UCSF) has contacted the Missing Maps project and asked for our help in completing a comprehensive building foot print map to aid their upcoming field work in 2016 as part of a final push at the total elimination of malaria in the Kingdom of Swaziland.

By helping map buildings you can play a part in this incredible effort to totally eradicate malaria from Swaziland by the end of 2016, a disease that once caused as many as 45,000 cases a year in Swaziland.

The building footprints you create as part of this project will be used by government health officers, NGO's and epidemiologists to support almost every aspect of their eradication efforts. These maps will be use for overall malaria surveillance programs, case tracking and management, coordination of indoor residual spraying programs (IRS), distribution of long-lasting insecticide-treated nets (LLIN), as well as information, education, and communication (IEC) campaigns.

The Missing Maps project aims to map the most vulnerable places in the world (affected by humanitarian crises: disease epidemics, conflict, natural disasters, poverty, environmental crises). Building on HOT's disaster preparedness projects, the Missing Maps tasks facilitate pre-emptive mapping of priority countries to better facilitate disaster response, medical activities and resource allocation when crises occur.

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

  • Only buildings need to be mapped
  • These task squares are big - feel free to use the "split" link you see after selecting a task square and clicking "Start Mapping"
  • In the iD web editor, a circle building can be made by drawing a triangle and then pressing the "o" key.
  • Validators: Expect there to be buildings not mapped, especially the brown roof huts, unless it is more than 15 mins worth of mapping, please just map them in.


  • 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.
  • changeset comments - These are filled in with some default information but you should always add what you mapped. For example "added buildings"
  • 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.
  • 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.
