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".

This area is divided into 3 different projects (1668, 1669, 1670), respectively on buildings, roads, and landuse/water points. The aim is to facilitate the work of new mappers as well as improve the quality of tracing.

For this second step of tracing, please map only the roads network. Do not map buildings or landuses, else it will create massive conflict errors with the other steps when saving your job.

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. And don't hesitate to mark tasks as done if they are complete, even if you didn't have to map anything on it!

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.
