United States Geological Survey, FISC St. PetersburgFall 2007Open File Report2007-1377St. Petersburg, FLUSGS\\EAARL Topography-Gulf Islands National Seashore-MississippiFirstvector digital dataextentRepresents the extent of usable Lidar data to a specific 2x2km tile.This shapefile was generated as an intermediate step to create a series of USGS LiDAR maps. The polygons represent specific regions of a 2x2km tile that have usable LiDAR data. All areas not covered by polygons correspond to areas of No Data on the LiDAR tile. This shapefile is particularly useful as an analysis mask within ARC Spatial Analyst.See the source Lidar GeoTIFF tile for more specific accuracy information.en20050901, 20050903, 20050904, 20050907, 20050908REQUIRED: The year (and optionally month, or month and day) for which the data set corresponds to the ground.ground conditionUnknown-88.507184-88.49604530.21604830.206721354943.000000356002.0000003342652.0000003343672.000000NONEExtentGulf Islands National SeashoreMississippiGulf of MexicoBare earth topographyAny use of these data signifies a user's agreement to comprehension and compliance of the USGS Standard Disclaimer.
