LiDAR Data Inventory

As part of the Coastal LiDAR Project conducted 2006-2009, FDEM cataloged all existing LiDAR data and related products (bathymetry and orthophotography) within areas of the state affected by hurricane surge. The following products are avaialable from those efforts, but are no longer being updated --

For the most recent inventory of LiDAR please visit United States Interagency Elevation Inventory.

LiDAR Data Distribution

Several internet accessible portals are now providing LiDAR and data derived from the FDEM Coastal LiDAR Project and other projects --

  • FIU's International Hurricane Research Center - provides tile-by-tile download of LAS and metadata files from the Florida Coastal LiDAR project. Currently has data for the entire FDEM project.
  • UF's Florida Geographic Data Library - provides 2 foot contours from the FDEM coastal project for the following counties: Bay, Brevard, Broward, Charlotte, Clay, Collier, Dade, Dixie, Duval, Escambia, Flagler, Franklin, Glades, Gulf, Hendry, Hillsborough, Indian River, Jefferson, Lee, Levy, Manatee, Martin, Monroe, Nassau, Okaloosa, Okeechobee, Palm Beach, Pasco, Pinellas, Putnam, Santa Rosa, Sarasota, St. Lucie, Taylor, Wakulla, and Walton. To easily access these data sets, follow this link and then on the next page click "Start Search".
  • Northwest Florida Water Management District - download contours, breaklines, DEMs, hillshade, LAS, and TINS for areas within the Northwest Florida Water Management District.
  • South Florida Water Management District GIS - has published the 10’ and 25’ DEMs for Broward, Miami-Dade, and Monroe delivery areas.  Use the GIS Data Catalog link to find the data. A good keyword for searching is “FDEM”.  Other delivery areas within the South Florida Water Management District will be available in the future. 
  • St. Johns River Water Management District GIS - has published digital elevation models for areas of Brevard, Clay, Putnam, and Indian River delivery areas.  Visit GIS Download Library to find available data.
  • USGS Seamless - provides digital elevation data from the National Elevation Dataset. Many Florida LiDAR projects have contributed to the available 1/9 arc second data.
  • USGS CLICK - provides download of LAS. Currently has data from FDEM coastal project for Sarasota and (from other projects).
  • NOAA's Digital Coast - provides many data download options both in terms of projection and datums, as well as file formats, cell sizes, and data classes. In addition to the FDEM project, also has data from the NWFWMD, SWFWMD, St Johns county, Volusia county, and coastal data from DEPís Beaches and Coastal Systems.

Additionally, the Southwest Florida Water Management District has 5 foot DEMs, LAS, breaklines, and contours for most of their district, including FDEM data from Pinellas, Hillsborough, Manatee, and Sarasota counties (contact Jessica Hendrix). NWFWMD has LAS and 1.2 meter or 2 meter DEMs for most of the panhandle counties from their LiDAR collects, and has 5 foot DEMs, LAS, breaklines, and contours for FDEM efforts from southern Escambia, Santa Rosa, Walton, and all of Wakulla counties (contact John Crowe). Data for other counties may be obtained by contacting Richard Butgereit at 850-413-9907.

SLOSH Data Development

A goal of the project is to use the LiDAR data as new elevation inputs for updated SLOSH data grids.

To receive email updates when SLOSH basins have been updated for the SLOSH Display program and/or have access to the SLOSH program data pages, go to http://slosh.nws.noaa.gov/sloshPub/disclaim.php, and register.

House Bill 7121 and LiDAR Data

House Bill 7121 - Disaster Preparedness Response and Recovery states, "The Legislature finds that hurricane evacuation planning is a critical task that must be completed in the most effective and efficient manner possible. Appropriated funds may be used to update current regional evacuation plans and shall incorporate current transportation networks, behavioral studies, and vulnerability studies. In addition, funds may be used to perform computer-modeling analysis on the effects of storm-surge events."

Florida Division of Emergency Management (FDEM) initiated an effort that resulted in the update of the Regional Evacuation Studies (RES) for the State. This process required updates to the coastal surge modeling tools with more current and accurate elevation data, i.e. LiDAR.

Baseline Specifications for LiDAR and Orthophotography

Florida Division of Emergency Management, several state and federal agencies, Water Management Districts, and several other critical stakeholders initiated an effort to develop baseline specifications for LiDAR and orthophotography. Starting with specifications from the Southwest Florida Water Management District (SWFWMD), baseline specifications intended to ensure that data acquired would provide a seamless statewide dataset for use by the broadest number of stakeholders.

LiDAR Data Collection

Beginning in 2006 and ending in 2009, FDEM cataloged all existing LiDAR data and related products (bathymetry and orthophotography) within areas of the state affected by hurricane surge. Existing LiDAR data products that met minimum specifications were acquired from their respective sources. Areas that did not have LiDAR data products meeting the minimum specifications were flown with the intent of capturing terrestrial LiDAR and orthophotography.
