This task is great for beginners. The data are prepared by MapSwipe, and the buildings are clearly visible on the imagery. Enjoy the mapping and help our teams!

Aweil, the capital of South Sudan’s Northern Bahr el Ghazal State, is home to tens of thousands of people, many of whom live on the city’s largely unmapped outskirts. Putting these settlements on the map is the first step to collecting crucial health and demographic data that will help MSF provide essential medical care to this underserved population. Mapping the Aweil region will allow MSF to conduct surveys to learn where patients live, where medical needs are most acute, and where seasonal peaks in illnesses like malaria and malnutrition are likely to occur.

MSF teams are mapping villages and taking their names on the ground, but identifying all of the inhabited areas and counting the structures is much more efficient from aerial photos. Knowing where all of the villages are scattered through the savanna helps us to map them, and counting the buildings within each village gives us a quick and fairly accurate method to estimate population. This is important to help MSF understand the spread of disease and identify areas of highest need.

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".

We have split the former #2419 task, into several smaller tasks, in order to reduce the load on the Tasking manager. Please, help us map this remaining part.

Have a look at this OSM diary before you start - it gives insight into how villages and buildings in Aweil appear on the ground and will help you with your mapping!

Please use the Bing imagery provided.

Trace and tag residential areas and the buildings inside them.

Please outline residential areas (more than two buildings / structures) and tag as landuse=residential (in JOSM) or Landuse Features=Residential Areas (in iD). Try to trace around all of the compounds, not just the houses; the compounds often extend well past the inner circle of houses but are definitely part of the village. You should be able to see compounds as they usually have a fence around them.

Buildings are generally round huts and should be tagged as Building Features=Building in iD and building=yes in JOSM.

There are keyboard shortcuts for tracing circular shapes in iD (the O key) and JOSM (also the O key).

This is the first stage of a three part process. The data in this task were pre-processed with MapSwipe.

JOSM contributors

Please download the global grid (gpx format) of this project and open it in JOSM in addition to the usual imagery and OSM database layers.
