Title: 2007 NCMP NY Ontario Laser Reflectance
Short Name: 2007_NCMP_NY_Ont_Laser_Ref
Status: Completed
Publication Date: 2009-05-13
Abstract:

The mosaic image contained in this file is comprised of the seafloor reflectance generated from the bathymetric laser energy. It contains multiple flightlines that were collected by the Compact Hydrographic Airborne Rapid Total Survey (CHARTS) system along the coast of New York. CHARTS integrates topographic and bathymetric lidar sensors, a digital camera, and a hyperspectral scanner on a single remote sensing platform for use in coastal mapping and charting activities. Data coverage generally extends along the coastline from the waterline inland 500 meters and offshore 1,000 meters or to laser extinction. Native imagery data is not generally in a format accessible to most Geographical Information Systems (GIS). Specialized in-house and commercial software packages processes the imagery data into GIS-compatible products for visualization and further analysis. Horizontal positions, provided in decimal degrees of latitude and longitude, are referenced to the North American Datum of 1983 (NAD83). Vertical positions are referenced to the NAD83 ellipsoid and provided in meters. The National Geodetic Survey's (NGS) GEOID03 model is used to transform the vertical positions from ellipsoid to orthometric heights referenced to the North American Vertical Datum of 1988 (NAVD88). The SHOALS 532 laser has also been radiometrically calibrated to be able to determine the same reflectance for an object on any given day or operating altitude. The seafloor reflectance is generated from individual bathymetric waveforms, rasterized, and then a mosaic is produced for each flight. The accuracy is within 5% of the true reflectance. The data file naming convention is based on the year, project, area name, "Box" number, and product type. An example file name is "2007_NCMP_NY_Ontario_Laser_Reflectance_070615_1206.tif," where 2007 is the year of data collection, NCMP is the project under which data were collected, NY_Ontario is the area of data collection, "Laser_Reflectance" is the product type, and 070615_1206 is the YYMMDD_HHMM for the start time of the flight.

Data Quality

Accuracy:

These data are not attributed. | Quantitative Value: N/A | Quantitative Test Explanation: These data are not attributed.

Horizontal Positional Accuracy:

The positions were obtained using post processed KGPS methods. The horizontal accuracy is better than +/- 0.75m.; Quantitative Value: 0.75 meters, Test that produced the value: 1 Sigma

Vertical Positional Accuracy:

The positions were obtained using post processed KGPS methods. The vertical accuracy is better than +/- 0.20m.; Quantitative Value: 0.20 meters, Test that produced the value: 1 Sigma

Completeness Measure:

Cloud Cover: Unknown

Completeness Report:

The imagery covered the required survey area with minimal gaps in data coverage.

Conceptual Consistency:

Tests for logical consistency indicate that all row and column positions in the selected latitude/longitude window contain data. Conversion and integration with vector files indicates that all positions are consistent with earth coordinates covering the same area. Attribute files are logically consistent.

Process Steps

Process Step 1

CC ID: 665038
Description:

These data were collected using the CHARTS system. It is owned by the Naval Oceanographic Office and operated through contract. The system collects topographic lidar data at 9kHz, bathymetric lidar data at 1kHz and RGB imagery at 1Hz using a Duncan Tech 4000. A CASI-1500 hyperspectral line scanner is integrated with the system as well. Aircraft position, velocity and acceleration information are collected through a combination of Novatel and POS A/V 410 equipment. All raw data streams are transferred to the office for downloading and processing in SHOALS GCS software. Aircraft position data are processed using POSPac software and the results are combined with the lidar data to produce 3-D positions for each lidar shot. Upon inspection and QA/QC in the software packages Fledermaus and PFM_ABE, anomalous data are flagged as invalid. The reflectance of each SHOALS 532nm laser return is generated using the Optech Rapid Environmental Assessment (REA) processor. The reflectance values range from 0.0 1.0, with 0.0 being full absorption and 1.0 being full reflection. The points are then converted to a raster within the REA processor. Gdalwarp is used to project the images from UTM to geographic space. The projection is defined within ArcCatalog as "The North American Datum of 1983." Data was processed from 20070615 - 20070723.
