Conversion of Historical Topographic Sheets (T-sheets) from Paper to Digital Form: Florida Everglades and Vicinity(A FGDC Compliant Metadata file is also available.) Metadata text files for each digital T-sheet can be accessed below. Identification_Information: Citation: Citation_Information: Originator: Smith III, Thomas J. Publication_Date: 20020115 Publication_Time: Unknown Title: Conversion of historical topographic sheets (T-sheets) from paper to digital form: Florida Everglades and vicinity. Open-File Report #02-204 Geospatial_Data_Presentation_Form: map Description: Abstract: Approximately 30 scanned T-sheets have been georeferenced in the Florida Everglades region. These georeferenced maps were combined, resulting in a single, georeferenced mosaic also available on this CD-ROM.| Due to space constraints, the georeferenced files (ex. 4371_geo.tif) are compressed. Uncompressed, unreferenced images (ex. t-4371.tif) included on the CD are useful for quick access to the data via many basic imaging software packages. The T-sheets are detailed survey maps issued by the National Oceanic and Atmospheric Administration's (NOAA) National Ocean Service (NOS), formerly the U.S. Coast and Geodetic Survey. These maps were produced to provide coastlines for use on navigation charts and contain survey marker locations, lines of latitude and longitude, and a representation of vegetation inland from the coast. Most of the South Florida maps on this CD are at 10,000 in the Sanibel Island vicinity not included as part of the digital mosaic. The maps are based on aerial photography from 1925 to 1935. The maps were published upon completion, some as early as 1931 and others based on supplemental survey data completed in October, 1937. Purpose: The Florida Caribbean Science Center (FCSC), a center of the U.S. Geological Survey's (USGS) Biological Resources Division (BRD) has created digital versions of existing topographic survey (T-sheets) for the Florida Everglades region. These digital files are available on this CD-ROM in a manner designed to facilitate access to the product by those 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.

Control points based upon lines of latitude and longitude on maps. These T-sheets were primarily created as part of survey of the area, lat/lon lines assumed to be drawn with care. Minimum RMS error of .5 acceptable. Logical_Consistency_Report: Original T-sheets created by NOAA/NOS, formerly the US Coast and Geodetic Survey. T-sheets georeferenced by Johnson Controls, contractor the the US Geological Survey, Biological Resource Division at the Florida Caribbean Science Center. Completeness_Report: All T-sheets available at US Geological Survey BRD Gainesville office been scanned and georeferenced. Other T-sheets in the South Florida area likely to have been created by USC&GS. Location of these maps is unknown.
