Identification_Information: Citation: Citation_Information: Originator: National Park Service South Florida/Caribbean Network Inventory and Monitoring Program Publication_Date: Summer 2007 Title: OFR_2007-1179 Geospatial_Data_Presentation_Form: vector digital data Description: Abstract: Represents the extent of a specific 2x2km tile that has usable Lidar data. Purpose: This shapefile was generated as an intermediate step while creating a series of USGS Lidar maps. Its 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 Spatial Analyst. Supplemental_Information: See the source Lidar GeoTIFF tile for more specific accuracy information.

Completeness_Report: This layer is complete. Lineage: Process_Step: Process_Description: The floating-point Lidar data needs to be converted to an integer raster. This is done with the Int() command within the Raster Calculator.
