Iraq Bombings Map

Sunday, January 13th, 2008

iraq big bombsMy colleagues at The Washington Post, Gene Thorp and Nelson Hsu, published an Iraq “Big Bombings” map recently using some Flash ActionScript code that I developed. The map allows you to track some of the deadliest attacks in Iraq since September 2006. Markers represent incidents in which 20 or more people were killed. Rolling over a marker will show that incident’s details.

The code behind the scenes is reading latitude and longitudes in decimal degrees and projecting the coordinates on-the-fly to the map’s Albers x-y space and scaling them to screen coordinates onto the base map. This makes updating the map’s thematic content a breeze since only the XML text file powering the thematic layer needs to be updated (the Flash base map doesn’t need to be regenerated).
