Title: 2018 Coastal Alabama RCD30 Natural Color 8 Bit Imagery
Status: Completed
Publication Date: 2018-12-04
Abstract:

The mosaic image contained in this file is comprised of multiple true color (RGB) images that were collected by the Coastal Zone Mapping and Imaging Lidar (CZMIL) system along the shoreline of Alabama. CZMIL integrates a lidar sensor with topographic and bathymetric capabilities, a Phase One iXU1000RS Digital camera, and a Itres' CASI-1500 hyperspectral imager on a single remote sensing platform for use in coastal mapping and charting activities. The PhaseOne camera imagery was collected at an altitude of 400m with a ground swath of 400m and delivered with a resolution of 5cm ground sample distance (GSD). Native PhaseOne imagery data is not generally in a format accessible to most Geographic Information Systems (GIS). Specialized in-house and commercial software packages process the imagery data into GIS-compatible products for visualization and further analysis. Horizontal positions, projected in Universal Transverse Mercator (UTM), are referenced to the North American Datum of 1983 (NAD83 2011). Vertical positions are referenced to the NAD83 ellipsoid. Individual image frames have been rectified and mosaicked into blocks commensurate with the collection blocks. Delivered data has been clipped to boundaries of Military Grid Reference System (MGRS). The data file naming convention is based on the year, project, area name, clip boundary, and product type. These file have been separated and delivered by JALBTCX collection blocks. An example file name is "2018_FEMA_PostMichael_FL_16RCU9742_RGB.tif", where 2018 is the year of data collection, FEMA is the Effort under which data were collected, PostMichael_FL is the area of data collection, the associated MGRS grid, and "RGB" is the product type. In rare cases file names may include whether data was collected at a nominal range of high tide (HT) or low tide (LT). The supplementary files are of the same name.

Purpose:

These data were collected as a part of the National Coastal Mapping Program (NCMP) to obtain Imagery of the existing conditions of the beach and near shore.

Data Quality

Accuracy:

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

Horizontal Positional Accuracy:

The data positions were obtained using post processed Direct Georeference PPK methods. The horizontal accuracy of the true color imagery operation is 12.2cm at 95% Confidence Level with typical RMSE is 7.1cm. Gross offsets in imagery data may be due to DEM affects or unforseen timing offsets caused by missed or unknown camera trigger times.

Process Steps

Process Step 1

CC ID: 867083
Description:

These data were collected using a PhaseOne iXU1000RS Digital Camera owned Teledyne Optech and on loan to the USACE Army Corps of Engineers Joint Airborne Lidar Bathymetry Technical Center of eXpertise (JALBTCX) and operated through contract with Woolpert, INC. The PhaseOne is a high quality, 100MP digital frame camera. All raw data streams were transferred to the office for downloading and processing. PhaseOne's COPE software was used to develop and in some cases color-balance the raw data into unrectified true color TIFF format images. All Iimage timing, position and rotational information was stored in Exterior Orientation (EO) file. The EO file along with the developed JPG or TIFF images and CZMIL Lidar based DEM were ingested into SimActive Correletor 3D. "SimActive’s Correlator3D™ software is a patented end-to-end photogrammetry solution for the generation of high-quality geospatial data from satellite and aerial imagery, including UAVs. Correlator3D™ performs aerial triangulation (AT) and produces dense digital surface models (DSM), digital terrain models (DTM), point clouds, orthomosaics and vectorized 3D features. Powered by GPU technology and multi-core CPUs, Correlator3D™ ensures matchless processing power to support rapid production of large datasets." Correlator 3D uses computer vision algorithms to refine the positional and rotational information of each frame relative to the surrouding frames. The result is a seamless, accurate, color balanced and tiled image mosaic. Tiles were generated from MGRS grids. The final mosaics were QA/QC ArcMAP with ground control points where available.
