Index maps that show the hydrography of the region and provide background for navigation tracklines were generated from standard USGS Digital Line Graph (DLG) datasets using Qeoquest CPS-3 software products. The hillshade maps showing topographical relief were generated from USGS gridded datasets using ESRI ArcView 3.0. Seismic profiles were scanned from analog copies. All page layout of figures and text was accomplished with the drawing programs Deneba Canvas, Adobe Illustrator and Adobe InDesign for Macintosh computers. In addition, internet translation was accomplished with Macromedia Dreamweaver and Macromedia Fireworks.

Reflective horizons from a lake that were laterally continuous and representative of a subsurface feature or the lake bottom were digitized using a standard digitizing table that have been eroded from the areas bordering the lakes have been deposited in the lakes and migrated downward into the space created by dissolution. The elevation of the bottom of these depressions may represent the base level of erosion as constrained by the potentiometric surface of the Floridan aquifer.

The hillshade views (for example, Index Map A) commencing the subsections were generated in ArcInfo from a grid of topographic elevations interpolated rom existing five foot contours depicted on USGS topographic maps. Data is projected to UTM, Zone 17, NAD 1983, 1990 correction and copied to double precision. Location of wells used for gamma log cross sections are included to show the proximity of well data to the study sites.
