DESCRIPTION:The French National Geographic Institute (IGN) came to Cambodia
  between 1952 and 1954 to carry out a large-scale photographic project\, t
 aking around 11\,000 aerial images over a large part of the country. \n\nT
 oday\, this collection represents an exceptional archive that takes us bac
 k 70 years to the urban and rural landscapes of the time. In addition to t
 hese early aerial photographs\, there is a higher resolution shot of Phnom
  Penh in 1993\, with incredible details of life in the streets of the capi
 tal. This archive is of great interest in many fields\, including history\
 , geography\, archaeology\, urban planning\, and ecology. The purpose of t
 he project is to dematerialize this archive and make it accessible and usa
 ble free of charge in Cambodia. \n\nAll the images were digitized and supp
 lied to the KHmer Earth OBServation (KHEOBS) laboratory to create orthopho
 tographs. Processing has been completed for the municipality of Phnom Penh
 \, for the years 1953 and 1993. In order to make these images viewable by 
 anyone\, a web application\, GeoCambodia\, was developed to visualize Camb
 odia then (past) and now (present). The user-friendly interface includes a
 n interactive slider to navigate and compare the old 1953 and 1993 aerial 
 orthophotographs with the recent Google Earth images. Also\, vector outlin
 es of buildings from 1993\, produced by the Atelier Parisien d’Urbanisme
  (APUR)\, have been integrated to enable visitors to click on a building a
 nd view the APUR’s descriptive architectural sheets. Other functions and
  the extension of the aerial images to the whole of Cambodia are still to 
 come in this interface.\n\nGeoCambodia.org targets anyone who is intereste
 d in aerial and satellite imagery and how Cambodia evolves through time an
 d space\, especially geography enthusiasts.
