creation of a geodatabase of the digital aerial photography archives for the greater everglades of south florida and the southern inland and coastal system
Creation of a Geodatabase of the Digital Aerial Photography Archives for the Greater Everglades of South Florida and the Southern Inland and Coastal SystemPoster presented April 2003, at the Greater Everglades Ecosystem Restoration Conference
[ Disclaimer ] Digital archives of historic aerial photographyThe project to create a digital archive of historical aerial photographs for the Greater Everglades is an important first step in the development of an understanding of the pre-drainage vegetation in the south Florida landscape. This knowledge is essential in the development of endpoints, restoration goals and performance measures to gauge restoration success. Work on the digital archive has progressed with the creation of two open file reports publishing maps from 1927-1935 and imagery from 1940.
Database developmentConcurrent with the development of the digital archive, information about the photography was recorded in a relational database using Microsoft Access. The data recorded included information on the flight, the photography, the scanning process and detailed information on each individual photograph. As of March, 2003, over 8000 photographs have been cataloged in the Everglades Historical Aerial Photographic Database.

Spatial integration of database and imagery in a geographic information system (GIS)
Creation of a geodatabaseTo test the geodatabase system as it applies to the Digital Aerial Photography Archives for the Greater Everglades of South Florida, a limited area was selected as a pilot project. The project consists of a geodatabase that includes georeferenced raster imagery from 1940, 1964 and 1987 incorporated with tables of detailed information about the photographs. It also includes vector files and raster imagery of the T-sheets that are based on a 1927 aerial photographic survey. The selected area corresponds to the Southern Inland and Coastal System of the Everglades. The geodatabase is part of the South Florida Information Access (SOFIA) clearinghouse and can be searched and used free of charge by accessing the SOFIA web address (http://sofia.usgs.gov/exchange/).
