Resource Abstract:
- description: The High Accuracy Elevation Data Project collected elevation data (meters) on a 400 meter topographic grid with
a vertical accuracy of +/- 15 centimeters to define the topography in South Florida. The data are referenced to the horizontal
datum North American Datum 1983 (NAD 83) and the vertical datum North American Vertical Datum 1988 (NAVD 88). The High Accuracy
Elevation Data Project began with a pilot study in FY 1995 to determine if the then state-of-the-art GPS technology could
be used to perform a topographic survey that would meet the vertical accuracy requirements of the hydrologic modeling community.
The initial testing platform was from a truck and met the accuracy requirements. In some areas, the surveying was accomplished
using airboats. Because access was a logistical problem with airboats, the USGS developed a helicopter-based instrument known
as the Airborne Height Finder (AHF). All subsequent data collection used the AHF. Data were collected from the Loxahatchee
National Wildlife Refuge, south through the Water Conservation Areas (1A, 2A, 2B, 3A, and 3B), Big Cypress National Park,
the Everglades National Park, to the Florida Bay. Data were also collected in the Lake Okeechobee littoral zone. The data
are available for the areas shown on the USGS High Accuracy Elevation Data graphic at https://sofia.usgs.gov/exchange/desmond/desmondelev.html.
The work was performed for Everglades ecosystem restoration purposes. The project started in 1995 and concluded in 2007.;
