USGS-NASA-NOAA-NPS EAARL Submarine Topography
The individual and merged submarine topography Lidar tiles are located in this Web site within the Lidar folder. A series of sub-folders house the edited Lidar DEM GeoTIFF, hillshade grid, contour shapefile, and tile extent shapefile for each specific map tile. These sub-folders are named according to their UTM coordinates of the upper-left corner (in thousands). Each GIS layer has an accompanying XML file that holds the metadata. The merged submarine topography data is also located in the Lidar folder within the merge sub-folder.
Located in the root directory of this Web site is a separate folder named Shapefiles. This folder contains all the vector data that was used to create the PDF map tiles. These layers include the state of Florida shapefile, and Lidar tile centroids.
All files are consistent with the UTM Zone 17N Coordinate System, NAD83 Datum, and GRS80 Spheroid.
