NOAA orthorectified Digital Elevation Model (DEM) image tiles, Bombay Hook, Delaware, 2011 (NODC Accession 0112173)

browse graphicPreview graphic
The NOAA Bombay Hook Project covers 177 square kilometers of the Bombay Hook National Wildlife Refuge and surrounding areas in Kent County, Delaware. The Dewberry company produced ortho mosaics for 101 tiles (1700 m x 1700 m) covering this area. The images were created with a 25cm cell size. These images provide a snapshot in time that depicts the ground surface and water features for use in coastal management. These Digital Elevation Models (DEMs) are created to the specifications outlined by NOAA CSC in partnership with the Delaware Department of Natural Resources and Environmental Control (DNREC).

These images are in ERDAS commercial software .img format which may be read by GIS software and various computer languages. Associated Reduced Resolution Dataset (.rrd) files, HIStory (.his) files, browse image (.jpg) files, and individual (.xml) and collection level metadata in Federal Geographic Data Committee (FGDC) format are included in the dataset.

Supplemental Information
Data set is not for use in litigation. While efforts have been made to ensure that these data are accurate and reliable within the state of the art, NOAA, cannot assume liability for any damages, or misrepresentations, caused by any inaccuracies in the data, or as a result of the data to be used on a particular system. NOAA makes no warranty, expressed or implied, nor does the fact of distribution constitute such a warranty.

The DEMs are derived from the source LiDAR. Vertical accuracy is not tested on the DEMs.

Based on the vertical accuracy testing conducted by Dewberry, using NSSDA and FEMA methodology, vertical accuracy at the 95% confidence level (called Accuracyz) is computed by the formula RMSEz x 1.9600. The dataset for the Bombay Hook project satisfies the criteria - Lidar dataset tested 0.14 m vertical accuracy at 95 percent confidence level, based on RMSEz (0.07 m) x 1.9600; Based on the vertical accuracy testing conducted by Dewberry, using NDEP and ASPRS methodology, consolidated vertical accuracy at the 95 percent confidence level is computed using the 95th percentile method. The dataset for the Bombay Hook project satisfies the criteria - Lidar dataset tested 0.11 m vertical accuracy at 95 percent confidence level in all land cover categories combined.
