Florida Integrated Science Center, USGS Unpublished Material Unknown vector digital data http://sofia.usgs.gov/publications/ofr/02-327/ Historical aerial photographs provide critical information about existing land cover conditions for use in land cover change studies. The historic aerial photographs of the Everglades show conditions of land cover change at intervals throughout the 20th century. In a project to create a digital archives of aerial photography of the Everglades, several sets of photography from varous time periods are being cataloged and scanned. As each photograph in the set was cataloged in the archives database, information about its identity, content and condition were recorded along with general data, when available, about the camera and flight. Mosaics of the scanned imagery were also scanned, when available, or constructed if necessary. These mosaics were georeferenced and used to develop shapefiles of flight lines and to calculate approximate center points of the photographs (xy coordinates). The center point coordinates were added as attributes to the archive database. A database query provided a table that was converted to a shapefile of center point coordinates and photograph attributes. The Florida Integrated Science Center (FISC), a center of the U.S. Geological Survey's (USGS) Biological Resources Discipline (BRD) has created a database of photography of the Florida Everglades region. This database has been imported into a geodatabase in ArcGIS 8.1 so as to facilitate the browsing and identification by researchers of historic photographs for ongoing and future scientific investigations. This data is of particular use to scientists intending to integrate the data with other spatial data, specifically those interested in the impacts of global climate change and land use change on coastal ecosystems. 19400214 19400522 ground condition Complete As needed -86.045482 -80.013831 27.308549 0.000000 None aerial photograph wetlands land cover historic photo flight line mapping None Everglades Big Cypress South Florida Dade County Collier County Monroe County Southwest Big Cypress Central Everglades None None Ann Foster U.S. Geological Survey, Florida Integrated Science Center mailing and physical address

Maps used to identify and name entities in the photographs included USGS topographic quadrangles and the "GNIS" geodataset pertaining to the Florida Geographic Data Library (FGDL) that give point coordinates and labels based on the USGS Geographic Names Information System (gnis). Point data are represented by a single pair of coordinates. The set of points for the centers of the 1940 photo collection are complete. The points were digitized mostly from reconstructed mosaics of the flight lines of photographs existing in the collection. In the case of missing,"nonexistent" photographs, several were assumed to exist based on earlier spreadsheet lists that show them as accounted for. It was possible to assign xy-coordinates to the point where the photograph is missing by estimating its location in the mosaic. It is possible that more photos from this set exist, unknown to us at the present time. In the case that more photos are discovered, the database will be updated. The center point coordinates for most of the images are not assumed to be accurate. The coordinates are estimates of the center point based on approximate locations of the images as they exist in a georeferenced mosaic. Most of the images are not georeferenced. A subset of photographs, those existing photographs pertaining to the Southern Inland and Coastal System, were georeferenced as part of a pilot project to develop a geodatabase of this area. The center point coordinates for these images are highly accurate, derived from the bounding coordinates of the georeferenced imagery.

Gainesville FL 32601 USA (352)372-2571 (352)374-8080 9am - 5pm Mosaic sheets were scanned, cropped and mosaicked to create one image. This larger image was georeferenced against a base map of the Florida coastline. This image was exported and developed into a .pdf image of the mosaics. Flight lines were digitized by estimating their position from the mosaics. A vector data file of flight lines was saved in ESRI ArcView shapefile format. Approximate center points were digitized based on the mosaic. The xy values for the center points were calculated and added as attributes to the center points vector data file. This information was copied into the archives database in Microsoft Access. A database query produced a table (.dbf) which was displayed and queried using ESRI ArcMap 8.3. The resulting shapefile shows all data points in set number 1 (1940), giving center point locations as well as other attribute data. 2003 40mos_sep13.img 40mosflightl.shp photoinfo.dbf sn01_1940xy U.S. Geological Survey, Florida Integrated Science Center mailing and physical address
