These files contain 3-band RGB orthorectified mosaic imagery tiles generated from data collected using a Phase One iXM-150F digital camera. This full frame medium-format aerial survey camera collected imagery data in tandem with a bathymetric lidar sensor and a hyperspectral imager on a single remote sensing platform. Native imagery data is not generally in a format accessible to most Geographic Information Systems (GIS). Specialized in-house and commercial software packages were used to process the native imagery data into 3-band orthorectified mosaic imagery that can be imported into GIS software for visualization and further analysis. Trajectories were transformed into positional coordinates using the HTDP (Horizontal Time-Dependent Positioning) software to maintain consistency with the NGS (National Geodetic Survey) reference to the North American Datum of 1983 (NAD83) and the North American tectonic plate coordinates realized from the National Adjustment of 2011, or NAD83 (2011). Horizontal positions, provided in decimal degrees of latitude and longitude, are referenced to NAD83 (2011) at the 2010.00 epoch. Vertical positions, provided in meters, are referenced to the NAD83 (2011) ellipsoid. NGS hybrid geoid model GEOID12B was used to transform the vertical positions from ellipsoidal heights to orthometric heights referenced to the North American Datum of 1988 (NAVD88). The imagery data are in TIF files tiled using 1 km boxes defined by the Military Grid Reference System (MGRS). The file naming convention references the year, effort, area, box number, and data product type. An example file name is, \u201c2024_NCMP_PA_17TPF2794_RGB.tif\u201d, where 2024 is the year of data collection, NCMP is the effort under which data were collected, PA is the area of data collection, 17TPF2794 is the box number and RGB is the data product type.<\/span><\/p><\/div><\/div><\/div>", "licenseInfo": "", "catalogPath": "", "title": "2024_NCMP_PA_RGB_Allegheny", "type": "Image Service", "url": "https://spatial.usace.army.mil/opjarcgis", "tags": [ "JALBTCX", "NCMP", "Pennsylvania", "Allegheny" ], "culture": "en-US", "portalUrl": "", "name": "2024_NCMP_PA_RGB_Allegheny", "guid": "", "minScale": 36901933.84449929, "spatialReference": "NAD_1983_UTM_Zone_17N" }
