Attributes were taken for each swallet as available. The list of attributes was determined by the project manager as needed for the study. |
The data for this report follows the consistency required of the project. Point locations were gathered using handheld GPS receivers; however, these data are not necessarily suitable for site-specific, cadastral, or other projects of similar intents. Please contact the FGS for further details. |
This dataset represents all known swallets as of July 2007. Subsequent updates are not currently planned, but may occur if and when new data are made available. |
FDEP Attributes meet the required accuracy of the funding grant. Accuracy is generally consistent with the type of GPS unit used to record locations; however, significant offsets may exist at sites which were inaccessible by foot. A complete Microsoft Access database of features is available. GeoPlan relied on the integrity of the attribute information within the original data. |
This dataset represents swallet locations that were within the scope of the Florida Springs Initiative / Florida Swallet Survey project. As such, not all Florida swallets are included in this dataset, and it is by no means comprehensive. Many documented swallets are located on non-public lands. These may or may not be accessible to the public and permission to access them MUST be granted by the property owner in advance of any attempt to visit these swallets. More information on Florida hydrogeology is available from the FGS online at http://www.dep.state.fl.us/geology/geologictopics/hydrogeo.htm FLORIDA GEOLOGICAL SURVEY - Glossary Swallet: See swallow hole. Swallow Hole: A place where water disappears underground in a limestone region. A swallow hole generally implies water loss in a closed depression or blind valley, whereas a swallet may refer to water loss into alluvium at a streambed, even though there is no depression (Field, 1999). SOURCE: http://www.dep.state.fl.us/geology/geologictopics/springs/sp_52.pdf |
The purpose of this data set is to provide locational reference to stream-to-sink features where surface waters enter karst features and interacts with Florida aquifers. |
Horizontal accuracy meets or exceeds the National Mapping Standards of 1947. GPS positional accuracy is within +/- 5 meters and in most cases +/- 1 meter depending on canopy and satellite availability. |
Vertical accuracy does not meet NMS 1947 standards as no vertical datum has been applied to this data. |
These data should not be used scales larger than 1:10,000. Data should not be used for engineering, survey, cadastral, or land conveyance purposes. Data were collected, processed, and corrected using a Trimble Pro-XR GPS receiver and GPS Pathfinder 4.2 software. FDEP GIS data is provided as a public service. FDEP makes every effort to provide accurate and complete data. Metadata is provided for all datasets and no data should be used without first reading and understanding the limitations of the data. The Florida Department of Environmental Protection (FDEP) provides NO WARRANTY as to the accuracy of this data or any corresponding attributes or metadata. Data is provided in an as is condition, without warranty of any kind, either expressed or implied, including any assurance that the data is fit for a particular purpose. FDEP shall have no liability, in any case, to the use of provided data (including redistribution and reproduction). Full liability, responsibility and consequence relating to the use of provided data rest with the user. |
The Florida Geographic Data Library is a collection of Geospatial Data compiled by the University of Florida GeoPlan Center with support from the Florida Department of Transportation. GIS data available in FGDL is collected from various state, federal, and other agencies (data sources) who are data stewards, producers, or publishers. The data available in FGDL may not be the most current version of the data offered by the data source. University of Florida GeoPlan Center makes no guarantees about the currentness of the data and suggests that data users check with the data source to see if more recent versions of the data exist. Furthermore, the GIS data available in the FGDL are provided 'as is'. The University of Florida GeoPlan Center makes no warranties, guaranties or representations as to the truth, accuracy or completeness of the data provided by the data sources. The University of Florida GeoPlan Center makes no representations or warranties about the quality or suitability of the materials, either expressly or implied, including but not limited to any implied warranties of merchantability, fitness for a particular purpose, or non-infringement. The University of Florida GeoPlan Center shall not be liable for any damages suffered as a result of using, modifying, contributing or distributing the materials. A note about data scale: Scale is an important factor in data usage. Certain scale datasets are not suitable for some project, analysis, or modeling purposes. Please be sure you are using the best available data. 1:24000 scale datasets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries. 1:100000 scale datasets are recommended for projects that are at the multi-county or regional level. 1:125000 scale datasets are recommended for projects that are at the regional or state level or larger. Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analysis. Every effort has been made to supply the user with data documentation. For additional information, see the References section and the Data Source Contact section of this documentation.

Florida Geological Survey - Hydrogeology http://www.dep.state.fl.us/geology/geologictopics/hydrogeo.htm Swallets mapped by the Florida Geological Survey http://ca.dep.state.fl.us/mapdirect/?focus=fgssinkholes |
Two full-time and several part-time researchers comb the first magnitude springsheds using topographic maps, aerial photos, USDA soil surveys, and local knowledge in search of potential swallets. With the property owner s permission, field teams make on-site investigations to determine if a feature qualifies and, if it does, it is then cataloged. A true swallet is a stream to sink feature, meaning there is a contribution area that concentrates runoff into identifiable streams that disappear underground at a specific point. The streams may be either intermittent or continuously flowing. Data collected includes: GPS points and areas using a backpack Trimble; length and width of pools and basins using a range finder; pool depths, if possible, using a hand-held sonar depth finder; color, clarity and visibility of the water in the pool using a secchi disk; photos are taken and written assessments are made of the geology, topography, vegetation, and notations of anything within a 150-meter radius.
