Description: The existing raster dataset corresponds to the year 1952, with data obtained from the UCSB Frame Finder Aerials, an online library collection database of aerial photography. The existing raster dataset contains two different flights, ABM-1952 and PAI-ABC, flown by Southwestern Aerial Surveys and Pacific Air Industries respectively, in order to provide a more comprehensive coverage of the city of Roseville. Some areas display apparent constrasts, such as plowed field vs. unplowed field, due to the fact that each flight was taken in different months in 1952. Both flights are displayed at a scale of 1:20:000The following photo frames were used to create the raster dataset: pai-abc_y8-144, pai-abc_y8-146, pai-abc_y8-140, pai-abc_y8-139, pai-abc_y8-141, pai-abc_y8-143, pai-abc_3k-28, pai-abc_3k-106, abm-1952_1k-68, amb-1952_1k-65, abm-1952_1k-28, abm-1952_1k-12, abm-1952_1k-67, abm-1952_1k-82, abm-1952_1k-80, abm-1952_1k-81, abm-1952_9k-84, abm-1952_9k-81
