Inhabitants of Harare, the capital of Zimbabwe, are facing some important water access problem, especially in area of recent settlements surrounding the capital. It leads to recurrent water related diseases like typhoid and cholera. MSF is currently working with local authorities in order to improve the water access in the most critical area. In the meantime, health authorities recently recorded cases of Typhoid, and even if cases numbers are still low, they are increasing. In order to help us taking the best decision possible, having the most accurate overview of everything related to water ways, roads and buildings in these areas would be an invaluable asset.

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".

Please note that many areas are already well mapped and that the Bing imagery is not very up-to-date, so don't delete existing data in case of doubt. You could use mapbox Imagery which is slightly more recent than Bing and align it to Bing imagery position. Don't hesitate to mark tasks as done if they are complete, even if you didn't have to map anything on it!

For beginners, we recommend you start on the tasks 1668 (buildings) or 1669 (roads).

Imagery

New mapbox imagery is available now on certain area of this project. If on your mapping area Mapbox imagery is available, please align this imagery to bing one first and then start mapping! Don't hesitate to help yourself by comparing Mapbox imagery to Bing one, it can make the interpretation work much easier; but don't forget that Mapbox imagery is the reference

Rivers / Water

  • Water ways : Mark waterways as : waterway=river
  • Area of water such as lake : Mark as natural = water

Buildings

For mapping buildings, please use the tag building = yes

Please rectangularize your buildings once it's done with S key in ID.

Please remember, you are mapping the footprint of the building, so please try and align the building shape with the base of the building and not the top.* Correct building mapping example: Buildings mapped at the top Vs buildings mapped at the base

Roads

The road conditions in Africa do not always correspond to their economic and social role. A road typology should be based on the road importance and not on the surface or the visual appearance of the road”. --Highway Tag Africa, OpenStreetMap Wiki. It can be hard to know the economic and social role of a road, but we can guess that a road is important to trace if it connects other roads, clusters of buildings, or towns and villages. Please use the tags below, taken from the OpenStreetMap Wiki:

  • Residential Road: The roads in residential areas, except major roads (i.e. primary, secondary, tertiary).

  • Unclassified Road: The roads serving for interconnection of smaller villages and hamlets. A road connecting two dwellings should be tagged as highway=unclassified (and not track or path event if it is not suitable for vehicles).

  • Tertiary Road: You might find some of these, they are roads interconnecting villages and the major streets in towns of some importance.

  • Do not map tracks: the small roads going outside the residential areas, mainly for agricultural and forestry purposes. In general these roads do not have a connecting function with other roads.

Always connect roads to other roads where they meet and never end roads on Residential or other area polygon edges.

For more information, please visit: Highway Tag Area WIKI page. or Bgirardot/West African HOT Mapping Tips

Landuse

Please map as much as you can such as forest, playground...

Please check at the wiki on landuse subject for specific tagging
