Name: Upper Floridan Aquifer System Potentiometric Surface
Display Field: ORIGINATOR
Type: Feature Layer
Geometry Type: esriGeometryPolyline
Description: Currently, contour lines are created for the potentiometric surface of the upper Floridan aquifer from water level data submitted by the water management districts. The points associated with the water level data are added to Geostatistical Analyst and ordinary kriging is used to interpolate water level elevation values between the points. The Geostatistical Analyst layer is then converted to a grid (using GA Layer to grid tool) and then contour lines (using the Contour tool). Manual editing is done to smooth the lines and fix areas that don't make sense. Errors are usually located where potentiometric highs are adjacent to potentiometric lows (areas where the gradient is high). Expert knowledge or additional information is used to correct the contour lines in these areas. Some additional data may be river stage values in rivers that intersect the Floridan aquifer or land elevation in unconfined areas. Contour lines created prior to May 2012 may be calculated using a different method.

Description: This layer represents the surficial and near-surface geology for over 20 years of STATEMAP geologic mapping. Each polygon represents the lithostratigraphic unit that is at or near the surface. Polygons were mapped at the 1:24,000 scale using samples from the FGS cores and cuttings repository, new core samples taken during the course of the project, extensive field work and surface sample collection, and computer modelling. Please note that much of Florida is covered with undifferentiated sediments, and by convention the FGS maps the first recognizable lithostratigraphic unit occurring within 20 feet of the land surface. Areas with >20 ft of undifferentiated sediments are mapped as Qu or Qbd. The original, published maps and reports for the STATEMAP projects can be found in the Open File Map Series and Open File Reports published by the Florida Geological Survey (Tallahassee, Fl). For the original published maps and reports, please see the Library page at http://www.dep.state.fl.us/geology/ or the STATEMAP ESRI Storymap at http://fdep.maps.arcgis.com/apps/MapJournal/index.html?appid=b4f5974ba6c44badabe574426f865908

Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Florida is divided into 10 regional districts which are subdivided into 71 sub-regional to local provinces. This classification system is based on landform similarities, the relationships to surrounding features, and geologic processes affecting the area, particularly coastal, fluvial, and karst processes. Districts have as few as two provinces up to 17 provinces. District and province description sections include Characteristics and Importance, Location, Important Geological Strata, Physiographic Characteristics and Boundaries, and Important Landforms and Sites. Geomorphic districts from earlier work in Alabama and Georgia were extended into Florida where appropriate.The “Florida Geomorphology Atlas” is a digital publication that includes a website and interactive WebApp with text descriptions for districts and provinces and accompanying spatial polygon data. The maps and data are not intended for site-specific purposes; however, they provide an informative and conceptual framework for understanding the landforms of Florida.</SPAN></P></DIV></DIV></DIV>
