Purpose: 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. Supplemental_Information: See the source Lidar GeoTIFF tile for more specific accuracy information.

Completeness_Report: This layer is complete. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: 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. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Elevations of the DEM are vertically consistent with the point elevation data, +/- 15cm.
