Dewberry produced Ortho Mosaics for 101 tiles (1700 m x 1700 m) covering this area. The Orthos were created with a 25cm cell size. Original contact information: Contact Org: NOAA Office for Coastal Management Phone: 843-740-1202 Email: coastal.info@noaa.gov These Orthos provide a snapshot in time that depicts the ground surface and water features for use in coastal management. These DEMs are created to the specifications outlined by NOAA OCM in partnership with the Delaware Department of Natural Resources and Environmental Control (DNREC). completed NOAA Office for Coastal Management (843) 740-1202 2234 South Hobson Ave Charleston SC 29405-2413 coastal.info@noaa.gov https://coast.noaa.gov WWW:LINK-1.0-http--link NOAA Office for Coastal Management Website NOAA Office for Coastal Management Home Page information pointOfContact NOAA Office for Coastal Management (843) 740-1202 2234 South Hobson Ave Charleston SC 29405-2413 coastal.info@noaa.gov https://coast.noaa.gov WWW:LINK-1.0-http--link NOAA Office for Coastal Management Website NOAA Office for Coastal Management Home Page information custodian asNeeded EARTH SCIENCE > SPECTRAL/ENGINEERING > INFRARED WAVELENGTHS > INFRARED IMAGERY EARTH SCIENCE > SPECTRAL/ENGINEERING > VISIBLE WAVELENGTHS > VISIBLE IMAGERY theme Global Change Master Directory (GCMD) Science Keywords 23.3 CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > DELAWARE place Global Change Master Directory (GCMD) Location Keywords 23.3 CAMERAS instrument Global Change Master Directory (GCMD) Instrument Keywords 23.3 Airplane > Airplane platform Global Change Master Directory (GCMD) Platform Keywords 23.3 DEM DMC Mosaic ORTHO Remotely Sensed Imagery/Photos theme DOC/NOAA/NOS/OCM > Office of Coastal Management, National Ocean Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2017-04-24 publication 8.5 Imagery project InPort otherRestrictions Cite As: Office for Coastal Management, [Date of Access]: 2011 Bombay Hook National Wildlife Refuge DMC Imagery [Data Date Range], https://www.fisheries.noaa.gov/inport/item/48396.

The required accuracy is 2 m or better at the 95% confidence level as computed in accordance with the FGDC National Standard for Spatial Data Accuracy (NSSDA).; Quantitative Value: 2 meters, Test that produced the value: The ground control was captured using Trimble R-8 GNSS receivers, which is a geodetic quality dual frequency GPS receiver. All locations were occupied once with approximately 38% of the locations being re-observed. All re-observations matched the initially derived station positions within the allowable tolerance of 5cm or within the 95% confidence level. 2 m or better at the 95% confidence level as computed in accordance with the FGDC National Standard for Spatial Data Accuracy (NSSDA). Vertical Positional Accuracy The DEMs are derived from the source LiDAR. Vertical accuracy is not tested on the DEMs. The vertical accuracy of the LiDAR was tested by Dewberry with 8 independent survey checkpoints. The survey checkpoints were evenly distributed throughout the project area. All 8 checkpoints were used to compute the Fundamental Vertical Accuracy (FVA). Project specifications required a FVA of 18 cm (0.18 m) based on a RMSEz (9 cm/ 0.09 m) x 1.9600. All checkpoints were also used to compute the Consolidated Vertical Accuracy (CVA). Project specifications required a CVA of 18 cm (0.18 m) based on the 95th percentile.; Quantitative Value: 0.14 meters, Test that produced the value: 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% 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% 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% confidence level in all land cover categories combined. Completeness Measure Cloud Cover: 0 Completeness Report A visual qualitative assessment was performed to ensure data completeness and compliance with project specifications. No void or missing data exists. Multiple tiles were added to the tile grid to fully cover the project boundary. Conceptual Consistency Data covers the tile scheme provided for the project area. The Raw imagery along with the DEM, AT, Camera calibration information were ingested into Image Station Orthopro. Orthorectified photos were then created. Seamlines were placed along natural and man made features that would mosaic the ortho images together based on a supplied tile grid. 2011-06-01T00:00:00 Metadata imported. 2011-07-06T00:00:00
