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.These data were collected as a part of the NCMP to obtain the existing conditions of the beach and near shore.enJune 15, 2007July 23, 2007 ground conditionAs needed-78.612561-77.98625643.39921843.345215-78.612561-77.98625643.34521543.399218ISO 19115 Topic Categoryoceans014imageryBaseMapsEarthCover010NoneU.S. Army Corps of Engineers, Mobile DistrictJALBTCXCHARTSSHOALSLaser_Reflectance imageGCMD Earth Sciences KeywordsOCEANS > COASTAL PROCESSES > COASTAL ELEVATIONLAND SURFACE > LAND USE/LAND COVER > LAND COVERGCMD Instrument KeywordsCAMERASGCMD Data Center KeywordsDOD/USARMY/USACE/SAM/MOBILEGeographic Names Information SystemUnited StatesNew York Lake OntarioGCMD Location KeywordsVERTICAL LOCATION > LAND SURFACENoneJuneJuly2007NoneThese images depict the existing conditions of the beach and nearshore at the time of the survey and are only accurate for that time.

The horizontal accuracy is better than +/- 0.75m.0.751 SigmaThe positions were obtained using post processed KGPS methods. The vertical accuracy is better than +/- 0.20m.0.201 SigmaThese 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."228-252-1111mailing and physical address7225 Stennis Airport Rd., STE 100KilnMS39556USA228-252-1121228-252-1133shoals-info@sam.usace.army.mil8am - 5pm Monday through FridayData Production ManagerJALBTCXUnknownThe imagery covered the required survey area with minimal gaps in data coverage.RasterPixel144052853510.0000490.00004932Upper LeftFALSENone1pixel RGBFALSE0.0000000.000000Decimal degreesNorth American Datum of 1983Geodetic Reference System 806378137.000000298.257224GCS_North_American_1983row and column0.0000490.000049North American Vertical Datum of 19880.01metersExplicit elevation coordinate included with horizontal coordinatesNorth American Vertical Datum of 19880.01metersExplicit depth coordinate included with horizontal coordinates20090427JALBTCXData Production Managermailing and physical address7225 Stennis Airport Rd., STE 100KilnMS39556USA228-252-1121228-252-1111228-252-11338am - 5pm Monday through Fridayshoals-info@sam.usace.army.milFGDC Content Standards for Digital Geospatial MetadataFGDC-STD-001-1998local timeenhttp://www.esri.com/metadata/esriprof80.htmlESRI Metadata Profile{4E3510EF-4790-42F2-A006-40B258AC6A91}2008081409062200FALSE20090427133336002009042713333600Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 2; ESRI ArcCatalog 9.2.4.14202007_NCMP_NY_Ontario_Laser_Reflectance_070621_1708.tif-78.612561-77.98625643.39921843.3452151-78.612561-77.98625643.39921843.3452151ISO 19115 Geographic Information - MetadataDIS_ESRI1.0datasetDownloadable DataTIFForthorectified imagery mosaicsno compression applied0.0000.000DVD-ROM or External Hard Drive by request228-252-1121JALBTCXData Production Managermailing and physical address7225 Stennis Airport Road, STE 100KilnMS39556USA228-252-1111228-252-1133shoals-info@sam.usace.army.mil20090427002file://\\alh-pogo3\pogo3\data2\datasets\macon\ontario_brf\geo\2007_NCMP_NY_Ontario_Laser_Reflectance_070621_1708.tifLocal Area Network0.000Raster DatasetGCS_North_American_19832127340.000049Degree10980.000049Degree1
