- Abstract:
-
This data represents half meter contours of the Florida Middle Keys. Fugro Pelagos Inc. (FPI) was contracted by the Florida Fish and Wildlife Conservation Commission (FWC) to collect and deliver bathymetric data derived from LiDAR measurements for an outer reef off the Florida Keys within the Florida Keys National Marine Sanctuary. The survey area includes the Outer Reefs off Vaca Key and Matecumbe Keys.
- Purpose:
-
The objective of the survey was to obtain SHOALS-1000T bathymetric LiDAR data for an area of a irborne LiDAR survey operations were carried out between March 14 and 18, 2007 (Julian day 073 to 077), during which the following types of information were collected: Bathymetric LiDAR data from the SHOALS-1000T, Digital Aerial Photography from the SHOALS-1000T and GPS Ground Control
The data provided here is the Sun Illuminated Bathymetry.
The bathymetric survey area was approximately 188.3 km2 in size. Water depths within the survey area (chart datum) ranged from 1.5 m (at shoals spots) to 35 m on the offshore SE side.
The bathymetric laser was operated to achieve 4m spot spacing flying at 300m altitude and approximately 162 knots. The survey lines were planned with 25% overlap, at a line spacing of 145m, covering a 165 m swath width. The bathymetric survey was required to meet IHO Order 1position and depth accuracy standards.
The LiDAR data were assessed for accuracy as best feasible. These data are the most detailed for this region and determining accuracy when compared to older, more coarse data is inconclusive. Since, no land is visible in the coverage, the data were qualitatively compared to known offshore reef sites for horizontal accuracy. The location of two lighthouse towers also provided insight into this accuracy. Results showed that the data lined up with the various reef structures inherent to this region (eg, spur and groove, reef crest).
- Supplemental_Information:
-
Prior to July 1, 2004, the Fish and Wildlife Research Institute (FWRI) was known as the Florida Marine Research Institute (FMRI). The institute name has not been changed in historical data sets or references to work completed by the Florida Marine Research Institute. The institute name has been changed in references to ongoing research, new research, and contact information.

Contours were generated using the spatial analyst extension in ArcGIS 9.3. The raster file containing the original lidar derived z-values was modified in raster calculator to exclude extreme outliers (i.e. values out of lidar range). Contours were generated from the modified raster in half meter intervals using a z factor of one.
