Estimating Local Populations in West Africa with Lights, Infrastructure, Other
Track: Sustainable Development and Humanitarian Relief
Author(s): Robert Leddy, Priti Mathur
Work is under way at the U.S. Census Bureau to develop a GIS-based methodology to estimate populations of individual cities, towns, and villages using nighttime lights and other satellite imagery, presence of local infrastructure, administrative boundaries, and NIMA's populated places. We will evaluate model output by using existing census data when available and contacts in the field. Such estimates would be invaluable in emergency responses to natural or human-induced disasters affecting countries for which recent detailed census data and reliable maps may not be available. Four countries in West Africa are serving as prototypes.
