This map illustrates changes in IDP settlement densities as visible in satellite imagery acquired 10 May 2012 and compared to imagery from 2 April 2012. IDP settlement areas defined by field staff were reviewed to determine changes in shelter density between these two dates. Of the 740 settlement areas reviewed, 20 had minor reductions in shelters, 11 had major reductions, 515 showed no change, and 2 indicated increases. Additionally 192 settlement areas were unassessed due primarily to cloud cover or lack of imagery and areas outside settlements were not reviewed. This is a preliminary analysis & has not yet been validated in the field; road data is incomplete due to gaps in the source data. Please send feedback to UNITAR / UNOSAT.
