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.See the source LIDAR GeoTIFF tile for more specific accuracy information.National Park Service South Florida/Caribbean Network Inventory and Monitoring ProgramSpring 2006extent_e304n2730vector digital data\\10.14.178.18\sero\LIDAR\DRTO\LIDAR\e304n2730\extent_e304n2730.shppublication date20060322CompleteAs needed-82.936965-82.91693324.67213824.653831304001.000000306001.0000002728000.0000002730000.000000ExtentDry Tortugas National ParkFloridaShapefileJudd PattersonNational Park Service South Florida / Caribbean NetworkResearch Assistantmailing and physical address

Palmetto BayFlorida33157United States(305) 252-0347(305) 253-0463The floating-point LIDAR data needs to be converted to an integer raster. This is done with the Int() command within the Raster Calculator.ESRI ArcGIS 8.3February 2006Then the Raster to Feature command is used to convert the data into a vector shapefile.ESRI ArcGIS 8.3February 2006An 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.ESRI ArcGIS 8.3February 2006Metadata imported.Z:\LIDAR\DRTO\LIDAR\e298n2722\extent_e298n2722.shp.xml2006052311540600Metadata imported.Z:\LIDAR\DRTO\LIDAR\e298n2722\extent_e298n2722.shp.xml2006052311590300This layer is complete.This layer was generated from an existing lidar tile.
