Remote sensing analysis by humanitarian organizations to detect and document changes related to displaced population camps has been employed, in various iterations, by the field for as long as two decades. The use of remote sensing to support responses to civilian displacement can prove valuable for site planning, identifying patterns of population change, and capturing key data for program planning and evaluation purposes.Recent advances in the amount of satellite imagery that is commercially accessible, as well as the adoption of technologies such as Google Earth, has enabled this form of analysis to become more prevalent among humanitarians. The rise of voluntary technical organizations (VTO) as part of the crisis mapping movement is a crucial factor in remote sensing’s more central role in supporting operations that assist displaced populations.
