- Map Feature:
This task is part of a long term consortium Disaster Risk Reduction program with the World Bank, Humanitarian OpenStreetMap Team (HOT), Ardhi University, Tanzania Red Cross Society, Danish Red Cross, Red Cross Red Crescent Climate Centre, University of Dar es Salaam, and Tanzania Commission for Science and Technology (COSTECH).
Please see instructions for details on how and what exactly to map.
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 preemptive mapping of priority countries to better facilitate disaster response, medical activities and resource allocation when crises occur.

Project Specific Mapping Notes
- A few of these squares may already be partially mapped, please review and map missing features if needed, fix up the existing mapping, or just mark it "Done" if already completely well mapped.
- Please use Bing Aerial Imagery, (or DigitalGlobe Premium if Bing is not clear).
- Please map roads as completely as possible by connecting them to the main road networks wherever 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 or on buildings.
You will most often use the following road classifications (JOSM): highway=primary, highway=secondary, highway=tertiary - These are major roads that connect large cities and span long distances. Many of these are already mapped, just be sure to map the unclassifieds and residential that run off of the existing mapped roads. highway=unclassified - This is for roads that a vehicle with 4 wheels could travel on that connect small villages and settlements. * highway=residential - These are roads that are in settlements that only are used for access to houses and buildings.
