United States Geological Survey FISC St. PetersburgDecember 2007Open File Report2007-1431St. Petersburg, FLUSGSEAARL Topography-Padre Island National SeashoreFirstvector digital dataRepresents the extent of usable Lidar data to a specific 2x2km tile.This shapefile was generated as an intermediate step to create a series of U. S. Geological Survey 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.en200509302005100120051002ground conditionUnknownNONEExtentPadre Island National SeashoreTexasUnited States Gulf of MexicoBare earth topographyAny use of these data signifies a user's agreement to comprehension and compliance of the U.
