A GIS Data Clearinghouse is a distributed system of servers located on the internet which contain descriptions of available digital spatial data and services. The fundamental goal of a clearinghouse is to provide access to digital spatial data and related online services for data access, visualization, or order.
The State of Florida does not currently have an official state GIS clearinghouse. However, numerous data resources exist within the state, including -
- Florida Geographic Data Library - a mechanism for distributing spatial data throughout the state of Florida, warehoused and maintained at UF's GeoPlan Center (make sure to see their Data Source Links)
- Florida Imagery at FREAC - high-resolution imagery and other data provided by FSU's Florida Resources and Environmental Analysis Center
- Florida Aerial Photography Archive Collection - high-resolution imagery provided by Florida Department of Transportation
- GIS Data Download - provided by Florida Department of Health
- Geodata Directory - provided by Florida Department of Environmental Protection
- GIS Data Directory - provided by Florida Department of Transportation
- GIS & Mapping Downloads - provided by Florida Fish and Wildlife Conservation Commission Fish and Wildlife Research Institute
- Central Florida GIS Clearinghouse - provided by Central Florida GIS
- Florida GeoSpatial Metadata Index - Funded by a USGS CAP grant through the Florida Institute of Government with technical support by FSU's Florida Resources and Environmental Analysis Center

The Federal Geographic Data Committee has established several key GIS data themes to be the framework within the National Spatial Data Infrastructure. These GIS data themes are believed to be the key to support the sharing of resources, improving communications, and increasing efficiency. Statewide data themes available are:
- Geodetic Control (the reference of geographic information to the actual ground position of the data) - provided by the Florida Department of Environmental Protection's Land Boundary Information.
- Cadastral (property boundaries and ownership) - provided by the Florida Department of Revenue.
- Orthoimagery (spatially accurate and ground referenced aerial photography) - provided by the Florida Department of Environmental Protection's Land Boundary Information.
- Elevation (digital data indicating the elevation above sea level at any point) - Elevation Contours and Depressions provided by the Florida Department of Environmental Protection and Bathymetry provided by the Florida Fish and Wildlife Research Institute.
- Hydrography (rivers, streams, lakes, etc.) - Florida National Hydrographic Dataset provided by the Florida Department of Environmental Protection.
- Administrative units (boundaries of cities, counties, and special purpose districts)
- Transportation (features such as roads, bridges, railroads, ports, and airports) - Many transportation data layers are provided by the Florida Department of Transportation. An airport facility locator is also provided by the Florida Department of Transportation's Aviation Office.
"Critical facilities" are defined as those structures from which essential services and functions for victim survival, continuation of public safety actions, and disaster recovery are performed or provided. Shelters, emergency operation centers, public health, public drinking water, sewer and wastewater facilities are examples of critical facilities. Please see Critical Facilities for more information.
Hurricane Evacuation zones (last updated on 8/14/2017) are designated by the Counties resulting from Statewide Regional Evacuation Studies.
Storm surge zones (last updated 8/14/2017) are derived from the Sea, Lake and Overland Surges from Hurricanes (SLOSH) MOM Basin, developed by the National Weather Service and updated during the Statewide Regional Evacuation Studies ranging from (2010-2013 & 2017). Maps are available for those counties with designated storm surge zones.
Surge Depth Inundation
These layers (last updated on 8/15/2017) provide an analysis to depict potential storm surge flood depth from the five categories of hurricane on the Saffir-Simpson Hurricane Wind Scale. Based on SLOSH Basin updates ranging from (2010-2013 & 2017) as part of the Statewide Regional Evacuation Studies.
Flood zones are geographic areas that FEMA has defined according to varying levels of flood risk. To find out about flood zones in your area, visit FloodSmart.gov, FEMA Map Service Center, and FEMA Mapping Information Platform.
To download a file geodatabase or shapefile of Statewide DFIRM flood zones, please click on one the links below:
- Zipped file geodatabase (ArcGIS version 10.4.1) (2.1 GB)
- Zipped shapefile (ArcGIS version 10.4.1) (1.4 GB)
A REST map service of Statewide DFIRM flood zones may be accessed at http://map.floridadisaster.org/GIS/rest/services/Hazards/Flood_Zones/MapServer and FEMA provides access to the National Flood Hazard Layer via KML.
Additionally, a few of Florida's Water Management Districts are involved in flood zone map modernization, and more details are available at the following websites -
