THE NEW GEOMORPHIC MAP OF FLORIDA

The last state-wide geomorphic map published by the Florida Geological Survey (FGS) at a 1:2,000,000 scale was released in 1964. Brooks published a geomorphic map of the state at a scale of 1:500,000 in 1982 but it was not widely utilized. The new geomorphic map is a combination of an upgrade of the 1964 map and a reinterpretation of the state’s physioography. Utilizing a combination of old-fashioned geological mapping techniques and modern, digital techniques, a new geomorphic map of Florida has been produced by the Florida Geological Survey. Initial mapping employed visual inspection of 1:24,000 scale topographic maps to identify physiographically similar areas then transferring those areas to a 1:750,000 scale map by hand. The resultant map was digitized. The digital outlines of the geomorphic features were overlain on to topography and aerial photography layers to aid in the resolution of boundary issues. Field checking of boundaries is occurring during travel for other FGS projects. The new map better identifies the karstic areas in Florida. This allows for a more complete understanding of the water resource issues surrounding Florida’s springs and the continuing intense development in the state.
