Haiti 2010 Earthquake Response

New map shows building damage across Haiti

The United Nations has issued an updated map of building damage resulting from the January 12 earthquake. The map (2.1 MB pdf), which covers Port-au-Prince and Carrefour, is one of many maps available from UNOSAT, the UN Operational Satellite Applications Program.

To create the map, satellite imagery and aerial photography were visually assessed and compared with pre-earthquake data. A technique called interpolation was used to compute additional points.  Later, the map will be revised using data supplied by workers on the ground.
