Overview of Spatial Data Digitizing with Open Street Map
Why? The Ebola Outbreak that struck Guinea in March 2014 later spread to Liberia, Sierra Leone and Nigeria causing at the beginning of August 1711 infections and 932 deaths. Aid organisations are taking emergency measures to contain the spread of this highly infectious and deadly virus. It is crucial for this work to drive rapidly through the territory and quickly locate those infected. Detailed and accurate maps of the region are vital, which is why organisations such as MSF, CartONG and Red Cross are working closely with the Humanitarian OpenStreetMap Team to coordinate our mapping community and deliver maps to field workers.

The Humanitarian OpenStreetMap Tream (HOT) coordinates mapping to aid "humanitarian relief by providing rapidly a detailed and accurate map to support the humanitarian organizations (ie. road network, villages, buildings, etc.). These services contribute to locate rapidly people at risk, facilitate delivery of goods and services to remote areas. The various epidemiological tools can also use these maps to monitor the situation." OpenStreetMap is built upon open data, which is freely available for use for any purpose with accredation and which is created and maintained by a community of mappers all over the world.
