Description:

Abstract:: This dataset contains Sensitive Karst Areas found within the Southwest Florida Water Management District. This is a subset of the data layer found on the map titled "Geologic Map of the State of Florida", created by the Department of Environmental Protection . This data layer is a reselection of the formation types that were determined to be "Sensitive Karst Areas". Karst is a terrain with distinctive landforms and hydrology created from the dissolution of soluble rocks, principally limestone and dolomite. Karst terrain is characterized by springs, caves, sinkholes, and a unique hydrogeology that results in aquifers that are highly productive but extremely vulnerable to contamination.
Purpose:: This data layer was created for a study done by the Regulatory Department to show depth to rock, and provide a possible tool for the evaluation of likely disturbances to the aquifer from detention ponds.
Supplemental_Information:: The groups that were determined to be "Sensitive Karst Areas" are: to = Eocene group, Ocala Ls; ts = Oligocene group, Suwannee Ls; that = Oligocene/Miocene group, Hawthorn Gp, Arcadia Fm, Tampa Mbr; tap = Eocene Group, Avon Park Fm.
What is Karst?
Karst is a terrain with distinctive landforms and hydrology created from the dissolution of soluble rocks, principally limestone and dolomite. Karst terrain is characterized by springs, caves, sinkholes, and a unique hydrogeology that results in aquifers that are highly productive but extremely vulnerable to contamination. In the United States, about 40% of the groundwater used for drinking comes from karst aquifers.
Some karst areas in the United States are famous, such as the springs of Florida, Carlsbad Caverns in New Mexico, and Mammoth Cave in Kentucky, but in fact about 20 percent of the land surface in the U.S. is classified as karst. Other parts of the world with large areas of karst include China, Europe, the Caribbean, and Australia.
Karst hydrogeology is typified by a network of interconnected fissures, fractures and conduits emplaced in a relatively low-permeability rock matrix. Most of the groundwater flow and transport occurs through the network of openings, while most of the groundwater storage occurs in the matrix. As a result, most karst aquifers are highly heterogeneous and anisotropic, and much of karst research has focused on developing innovative approaches for better understanding and managing these valuable water resources.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:: The SWFWMD has completed no formal accuracy assessment. It is assumed that the attribute accuracy is 100%.
GeoPlan relied on the integrity of the attribute information within the original data.

Logical_Consistency_Report:

The final product was checked against the source material. The Mapping and GIS section of the Southwest Florida Water Management District corrected any errors found.

Completeness_Report:

The following groups were determined to be "Sensitive Karst Areas" and are the only formations found in this layer. to = Eocene group, Ocala Ls; ts = Oligocene group, Suwannee Ls; that = Oligocene/Miocene group, Hawthorn Gp, Arcadia Fm, Tampa Mbr; tap = Eocene Group, Avon Park Fm.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:: The District has completed no formal accuracy assessment. It is assumed the data meets the National Map Accuracy Standards for scales of 1:100,000.

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:: This data is provided 'as is' and its vertical positional accuracy has not been verified by GeoPlan

Process_Description:

The shapefile, Geologic Formations of Florida, was downloaded from FDEP's ftp site. It was converted into a coverage and reprojected to UTM, zone 17, meters, HPGN using ArcGIS 8.2 software (ArcToolbox). The coverage was built for polygon topology. The fuzzy tolerance was set to 0.001. This layer was clipped to the District boundary using ArcToolbox.
The Mapping and GIS Section was given a list of the formations deemed to be "sensitive Karst areas" by the Regulatory Department. Using ArcMap 8.2, the FORM_CODE was used to select the "sensitive Karst areas". The selection was then exported as a new layer. - stratigraphy

Process_Description:

An enterprise geodatabase was designed and implemented. Coverages were converted into feature classes using ArcCatalog 8.3. The feature classes were created new in a feature dataset, with column names, shape type, grid size, and projection information defined during creation. An X/Y Domain and Precision were set at MinX: -700,000; MinY: 2,000,000; Precision: 1000. Z-Values were set at MinZ: -20; Precision: 1000. The Grid Tile Size is 30,000. Data was then loaded into the feature classes from the coverages using the 'Load Data' tool in ArcCatalog 8.3.
