This coverage includes every major lake but is not a complete coverage of the lakes in Florida. South Florida is not included in this coverage. Lakes data will likely be updated in the future to include agency developed waterbody IDs for each lake. Also, USGS GNIS naming board will be given the chance to check and approve the determined lake names. If/as this effort is accomplished, GNIS IDs may be added to the attribute data. FDEP: This data is intended to be used for general informational and planning purposes, and is not appropriate for legal and/or cadastral purposes. FDEP: The data set is NOT a survey document and should not be utilized as such. 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.

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.

GNIS Lake Points were used as reference points to find the lakes. The GNIS points were then checked against the 1995 Digital Ortho Quadrangles (DOQs). The points were then moved if necessary to represent the center of the lakes, or the point most likely to remain water during drought. Other points were added to represent lakes that did not have GNIS points. The names of the points were then checked against the Digital Raster Graphics and other resources. The USGS Hydrography layer was then clipped to the point coverage, so that there was a layer of just the polygons that intersected the points. The polygon coverage was then cleaned up to match the 1995 DOQs and given the appropriate name from the point coverage. The lakes that did not have names were sent to the respective Water Management District lake biologists for QA/QC. Additional QA/QC included the following: A LINK field was developed to ensure point + polygon correspondence 373 Duplicate Names were investigated 252 names had blank spaces before the Name that had to be removed County Names were compared to DEP Standards Unnecessary fields were removed Process Date: 20020409 |
