Identification_Information: Citation: Citation_Information: Originator: Canaan Valley Institute Publication_Date: April 2004 Title: LiDAR Raw Data Tiles Geospatial_Data_Presentation_Form: vector digital data Online_Linkage: \\bigsandy\X\projects\gilmer_little_kanawha\lidar\reference\rawdata_tiles.shp Description: Abstract: Polygon coverage of data tiles delivered by LiDAR contractor, Airborne 1. Two corresponding text files of LiDAR data exists for each polygon (bare earth points and extracted points). The polygons are 1km x 1km square, but it should be noted that the corresponding text file may not constitute complete edge-to-edge coverage for some polygons due to the irregular nature of the data acquisition boundary. Purpose: Reference coverage to help in the organizaiton of the raw data text files delivered by Airborne 1 for the Gilmer County, WV LiDAR acquisition area. This project is being conducted as part of a FEMA Cooperative Technical Partners grant for floodplain mapping initiatives. The project is foucsed on Gilmer County and the Little Kanawha subbasin below Burnsville Dam.

This is an inconsistency that only affects the exterme edges of the acquisition area. Logical_Consistency_Report: Tile size and distribution are consistent. However, it should be noted that the data delivered for each tile polygon may not constitute full edge-to-edge tile coverage due to the nature of the irregular data acquisition boundary.
