This 2015 Digital Elevation Model Elevation Product has been provided by USGS and is hosted as an image service by Louisiana DOTD. This service has a spatial resolution of approximately 1-Meter(s) and an extent covering Gulf Islands areas of interest. The source data for this service has horizontal coordinate system 'NAD 1983 UTM Zone 15N (EPSG: 26915)' and vertical coordinate system 'NAVD 1988 (EPSG: 5703)'. The source data is in TIF format. The no data value for this data is NoData. The source data bit depth is 32-Bit Floating Point. This data is not available for download. In 2015, Digital Aerial Solutions, LLC (DAS) was tasked by USGS to collect and process a Lidar derived elevation dataset for South Terrebonne and Gulf Islands. The South Terrebonne and Gulf Islands LiDAR survey encompasses approximately 2093 square miles. LiDAR data collected for the South Terrebonne and Gulf Islands survey area has a nominal pulse spacing of 0.7 meters.
