Geological Survey, FISC St. Petersburg Publication_Date: July 2007 Publication_Time: Unknown Title: EAARL Topography-Assateague Island National Seashore-Contour line shapefile Geospatial_Data_Presentation_Form: vector digital data Description: Abstract: Contour lines derived from a LiDAR GeoTIFF. Purpose: This contour shapefile was generated from a LiDAR GeoTIFF. It shows contour lines at 1 meter intervals, and will be used to aid the interpretation and display of LiDAR data. Supplemental_Information: See the source LiDAR GeoTIFF tile for more specific accuracy information.

Completeness_Report: Contour lines break where there was no data (value of -100) in the original LiDAR tiles. Lineage: Process_Step: Process_Description: The LiDAR GeoTIFF was too coarse to create aesthetically pleasing contours, so the first step was to run a Neighborhood Statistics operation on the LiDAR GeoTIFF. The settings for this Neighborhood Statistics were a 14x14 cell rectangle using the mean as the statistic type. This was output to a temporary raster grid.

The temporary Neighborhood Statistics grid was used as the input surface and the contour interval was set to 1 (meter). This was output to a permanent shapefile.
