Identification_Information: Citation: Citation_Information: Originator: National Park Service South Florida/Caribbean Network Inventory and Monitoring Program Publication_Date: Spring 2006 Title: Biscayne National Park tile extent 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.

Process_Date: December 2005 Process_Step: Process_Description: An attribute query is run to locate polygons with a GRIDCODE value of -100. An edit session is started on the shapefile, the queried polygons are removed using the delete key, edits are saved, and the edit session is ended.
