These files contain 4-band RGBN orthorectified mosaic imagery tiles generated from data collected using a Leica RCD30 digital camera. This full frame medium-format aerial survey camera collected imagery data in tandem with a bathymetric lidar sensor 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 4-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. 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, 2024_FEMA_FL_17RLL5013_RGBN.tif, where 2024 is the year of data collection, FEMA is the effort under which data were collected, FL is the area of data collection, 17RLL5013 is the box number and RGBN is the data product type. These data were collected by the USACE in support of FEMA to obtain imagery of conditions along the coast of Florida.

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. Leica RCD30 data were converted from raw files created during the data collection to unrectified TIF images using HxMap which is a data processing suite developed by Hexagon. A Smoothed Best Estimate of Trajectory (SBET) solution was resolved from the raw aircraft GNSS-IMU positional data using the NovAtel Inertial Explorer software package. The Exterior Orientation (EO) parameters and camera misalignments for the imagery were then computed using the Leica IPAS CO+ software package where the values were checked against the known current calibration values for this camera installation. A Digital Elevation Model (DEM) was generated from lidar data collected concurrently with the imagery using an adjacent sensor in tandem with the digital camera on a single remote sensing platform. The unrectified TIF files, EO data, DEM file, SimActive Tile Definition File (TDF), and camera calibration file were given as input to the SimActive Correlator3D software package for processing. Using Correlator3D, the data went through Aerial Triangulation (AT), orthorectification, color balancing, and mosaicking. The mosaic data were exported from Correlator3D as TIF files tiled according to 1 km MGRS grid cells. The mosaic image files were compressed using Geospatial Data Abstraction Library (GDAL) tools by applying the LZW lossless compression method. The compressed mosaic image files were finalized using GDAL and the Esri ArcGIS Desktop software package. GDAL was used to calculate statistics and build pyramids, while ArcGIS was used to create metadata for each image tile. The data processing workflow, including software packages, algorithms and parameters are provided in detail, within this metadata as Process Steps. 2024-11-01T00:00:00 These data were collected using the Leica RCD30 digital camera. The camera is owned and operated by Woolpert, Inc. and used in support of the U.S. Army Corps of Engineers (USACE) Joint Airborne Lidar Bathymetry Technical Center of eXpertise (JALBTCX). The RCD30 is one of Leica's medium-format full frame aerial survey camera specifically designed for mapping applications. The Leica RCD30 can capture high-resolution RGBN (Red Green Blue NIR) imagery with a wide aerial coverage. Aircraft position, velocity, and acceleration information was collected as raw positional data which creates a GNSS-IMU solution for airborne direct georeferencing which precisely measures the position and orientation of the onboard aerial sensors hundreds of times per second and accounts for all motion variables at the exact moment of data capture. All raw data streams from the collected mission, including the raw files from the Leica RCD30 digital camera and the positional data, were then transferred from the field to the office for downloading, duplicating, and processing. 2024-11-23T00:00:00 After collection, the navigation data was refined with the NovAtel Inertial Explorer software package. A copy of the raw positional data from the on-board navigation system was used as input for the navigation post-processing. After post-processing, the lever arms and mounting angles were verified to match the values of the current camera installation. Upon satisfactory review, an SBET file was exported from Inertial Explorer using the World Geodetic System 1984 (WGS 84) method where the position data was referenced to the ITRF2014 datum with an epoch targeting the mission date. An ITRF (International Terrestrial Reference Frame) is a realization of the ITRS (International Terrestrial Reference System) which through various scales, rotations, and rates applied to its origin are updated for geodetic use as time goes on by producing new solutions every few years. Over time, the WGS 84 reference coordinate system used by the Global Positioning System (GPS) has had several re-adjustments to keep it in line with ITRF updates. This SBET file was then transformed from the ITRF2014 datum with an epoch corresponding to the mission date 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) at the 2010.00 epoch. The National Geodetic Survey (NGS) has produced several adjustment realizations to NAD83, including NAD83 (2011). While WGS 84 is updated to match ITRF realizations, NAD83 is tied to the North American tectonic plate where its coordinates have been gradually drifting farther from the WGS 84 and ITRF adjustments with the passage of time. 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. 2024-11-01T00:00:00 The copy of the raw Leica RCD30 data was converted from raw files created during the data collection to unrectified TIF images using HxMap which was developed by Hexagon. Using HxMap, associated data was extracted from the raw camera data to derive the event file, photo ID file, preliminary Exterior Orientation (EO) file, and installation settings file. Using Leicas IPAS CO+ software package, the SBET file was converted to a solution file format usable by IPAS CO+. This solution file, event file, photo ID file, and valid lever arm misalignment values were used by IPAS CO+ to create and export the finalized Exterior Orientation (EO) values as a text file. Using a custom Python script, this text file was then restructured into a format usable by Correlator3D. The unrectified TIF imagery was then subjected to image processing using the SimActive Correlator3D software package. The TIF images, concurrent DEM image, EO file, SimActive Tile Definition File (TDF), and camera installation file were used to build a project in Correlator3D. Aerial Triangulation (AT), orthorectification, color balancing, mosaicking, and tiling were done in a preliminary manner and the data was reviewed. The AT report was reviewed to ensure a satisfactory quality assessment and limited projection error. The automatically generated seamlines were manually adjusted to correct unsatisfactory mosaicking patterns. Next, the corrected mosaic data were exported from Correlator3D as TIF files tiled according to 1 km MGRS grid cells. The mosaic image files were compressed using Geospatial Data Abstraction Library (GDAL) tools by applying the LZW lossless compression method. GDAL was then used to calculate statistics and build pyramids on the compressed mosaic image tiles. The Esri ArcGIS Desktop software package was then used to create metadata for each image tile. 2024-11-01T00:00:00 Source Contribution: 7225 STENNIS AIRPORT RD STE 100 Kiln, MS 39556 JALBTCX@usace.army.mil 228-252-1131 JALBTCX Data Production Manager originator 2024-11-16
