Abstract This project represents a timeslice series of historical aerial photography datasets around Warrnambool-Mepunga, Kingston, Latrobe Valley and Mallacoota from the 1930's to the 1990's.The purpose of creating the ortho photo mosaics was to detect and measure changes (long term, progressive or cyclic). The type of shoreline change the photography aimed to identify included sandy beach-dune, scarped 'soft-rock', muddy mangrove shores and asset removal/construction. A secondary purpose of the photography was to map the change of vegetation. To achieve the purpose, a time series of repeated aerial photography was planned with epoch intervals of approximately 10 years (and a minumum of five years separation). The seven epochs planned for were 1930's,1940's,1950's,1960's,1970's 1980's and 1990's. For any given epoch where the study area was not covered completely by a historic photography project (series of air-photos taken on the same date or within a few days of each other) then the next most recent photography project was identified, processed and used for comparison. The aim was to keep each epoch as close as possible, This data is only available for Whole of Victorian Government use.
