  • Author: Missing Maps
  • Requesting Organization: MSF
  • Priority: Low

Médecins Sans Frontière is working in Bunia, RDC, a fast growing city (capital of the province) on preventing cholera crises and security issues. In order to help them make the best decisions possible, having the most accurate overview of everything related to 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.

See below a short introduction by Jean-Pierre WEZA, Field GIS Officer, MSF, of the cartography need in this area. Please select Parameters / Subtitles , to see the english translation.

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

The priority area is dedicated to beginners. As the road network is mainly completed, beginners can learn smoothly starting with building mapping in this area.

Buildings

For mapping buildings, please use Building > Building in ID or building = yes in JOSM.

Do not map buildings as houses

Please make your buildings square once it's done with S key in ID, or Q key in JOSM

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.
