United States Geological Survey FISC St. Petersburg, 600 4th Street South, St. Petersburg, FL 33701 Fall 2007 Open File Report 2007-1375 St. Petersburg, FL USGS \\ Ope File Report USGS extent_e412_n4644-2extent_e412_n4644-2vector digital data Represents 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. en 20050504 ground condition Complete Unknown -70.061611-70.04947741.94318541.925057 412001.000000412982.4899904642000.0000004644001.000000 NONE Extent Cape Cod National Seashore Massachusetts United States East Coast Atlantic Coast Bare earth topography 20050504 Any use of these data signifies a user's agreement to comprehension and compliance of the USGS Standard Disclaimer.

Unclassified Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 2; ESRI ArcMap 9.1.0.722 Shapefile This extent layer was generated from existing LiDAR tile data using ARCMap 9.1. This layer is complete. Raw elevation measurements have been determined to be within 1.5 meter horizontal accuracy. Processing steps (grid interpolation) may introduce additional error which has not been tested at the time of this publication. Elevations of the DEM are vertically consistent with the point elevation data, +/- 15cm. computer program 20070329 ground condition The floating-point LiDAR data required conversion to integer raster. This was done with the Int() command using ARC Raster Calculator. 20070329 United States Geological Survey-FISC St. Petersburg mailing and physical address
