This map presents a satellite-based estimation of the number of civilians leaving the capital city of N'Djamena towards Kousseri, Cameroon on Monday, 4 February 2008. This estimate is based on an crowd density analysis of a WorldView-1 satellite image acquired at a spatial resolution of 50 cm. The resulting estimate of 15,000 people represents only pedestrians at two bridge locations at approximately 10:30 UTC, and does not reflect those who crossed later in the day. This is a preliminary estimate, and has not yet been validated in the field. Map Scale for A3: 1:2,000; Projection : UTM Zone 33 North; Datum: WGS 1984
