The American Red Cross and Tanzanian Red Cross are beginning long term disaster risk reduction programming in rural Ushirombo, Tanzania. The Red Cross hopes to capture GIS data using OSM and needs more detailed basemap data (roads, land features, rivers) to assist in the project design phase. The maps produced will be used to create more efficient and grounded programs to reduce the risk or disease and environmental disaster from affecting the communities.

The purpose of this task is to trace roads, rivers, land features, all buildings, and other landmarks.

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.

The Red Cross is starting some long term programming in Tanzania. The Red Cross hopes to capture GIS data using OSM and needs more detailed basemap data (roads, land features, rivers) to assist in the project design phase.

The purpose of this task is to trace roads, rivers, land features, all buildings, and other landmarks.

Instructions

Please trace areas of housing (landuse=residential), buildings (building=yes) and map roads and smaller paths for as far as you can follow them (see below for useful tags and resources).

Save with credit to HotOSM. Comment the changeset with: #hotosm-project-955 #MissingMaps #RedCross

Please use Bing imagery

Commonly used tags and useful resources:

Residential areas:

  • landuse=residential for a border around a cluster of residential buildings
  • building=yes for rectangular & round buildings - trace the building outline
  • building=construction for walls without a roof

Road networks

  • highway=primary, secondary or tertiary for main roads connecting towns
  • highway=residential inside residential boundaries
  • highway=track only goes to farmland
  • highway=path - not even a 4x4 can get down this

Waterways

  • waterway=river for centreline on waterway
  • waterway=riverbank for river banks!
  • waterway=stream
  • waterway=* & intermittent=yes - path of a seasonal river or stream - depends on the time of year as to whether water present
  • natural=water & water=lake for lakes

Other useful tags

  • leisure=common for large open areas (not fields, just smooth open ground next to towns) as as these are potential helicopter landing sites.
  • amenity=school - school areas are easily identified as 1 or 2 long buildings at the edge of the village, sometimes with two small toilet buildings behind them. The schools are almost always accompanied by a large open area for the children to play in, tag the whole area of the school complex with amenity=school and trace the school buildings and bathrooms.

See the the OSM map features page for more info.
