The base station was located at Ted Stevens Anchorage International Airport and the FBO was at Million Air in Anchorage Alaska. Precise Latitude 61 09 51.89 (dms), Longitude -149 58 51.91 (dms), Ellipsoidal Height 61.838 (m). Logical_Consistency_Report: Any anomalies in the GeoSAR DEM such as noise, spikes, or wells are remediated during a DEM inspection. Proprietary Fugro Geospatial software is used to remove identified pixels and interpolate the voids; ensuring logical consistency of the GeoSAR DEM. LiDAR profiler data is used to validate the consistency of the GeoSAR DEM. The GeoSAR DEM, GeoSAR ORI, GeoSAR DTM and GeoSAR DSM are computed using the same bundle adjustment to ensure co-registration between products. Completeness_Report: The data is checked for completeness by ensuring that the GeoSAR DEM, ORI, DTM and DSM cover the entire project area. Due to processing differences between the ORI and DEM data, there are some islands present in the ORI data that have elevation data in the DEM equal to the water surrounding the islands. These areas have purposely been left as islands in the ORI data and filled with hydro elevation values in the DEM data. Voids found in the GeoSAR DEM are filled by interpolation or adjusted elevation data from the National Elevation Dataset (NED) using proprietary Fugro Geospatial software. All voids are recorded in the Voids_With_Fill_Surface shapefile. The islands mentioned above are identified in the void shapefile as filled with GeoSAR Hydro Elevation. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Prior to acquisition ground reflectors were placed in project area and surveyed for their precise location. Proprietary Fugro Geospatial software is used to locate reflector sites in GeoSAR DTM and DSM. Reflector locations in GeoSAR DTM and DSM are compared to surveyed ground locations using proprietary Fugro Geospatial software to evaluate horizontal accuracy. Reference Quality Report for results. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: LiDAR profiler data is automatically filtered to select points in open terrain throughout the project area. The filtered LiDAR data set is then used as control points in analyzing the vertical accuracy of GeoSAR DTM and DSM. Proprietary Fugro Geospatial software is utilized for comparing the GeoSAR DTM and DSM to LiDAR control points. Prior to acquisition ground reflectors were placed in project area and surveyed for their precise location. Proprietary Fugro Geospatial software is used to locate reflector sites in GeoSAR DTM and DSM. Reflector locations in GeoSAR DTM and DSM are compared to surveyed ground locations using proprietary Fugro Geospatial software to evaluate vertical accuracy. Reference Quality Report for results.

The mission consisted of 13 sorties, 68 flight lines, and 24,345 linear kilometers. Process_Step: Process_Description: Once the motion data and respective raw data were collected and delivered, an initial quality check was performed. Preliminary MMP (Motion Measurement Processing) is a proprietary program in which the motion data of each segment was analytically viewed in graphical form for the determination of which data was within specifications and therefore should be used in product. At this point the acceptable raw data were registered to the motion data as 32 bit magnitude and elevation files and were ready to be unwrapped, viewed, and edited.

Each segment is setup for and interferometric processing and edited for anomalies, artifacts, dropouts and incorrect ambiguities. Finally, a proprietary radiometric program was run to balance intensity values and the segments were ready for mosaicking.

Using these common points, a best fit solution is determined. Swaths are combined using the best fit solution to create final GeoSAR ORI, GeoSAR DSM, and GeoSAR DTM mosaics; during this process the swaths are converted from a local coordinate system to a global coordinate system. The finished mosaics are inspected and packaged for delivery. The final GeoSAR ORI, GeoSAR DSM, and GeoSAR DTM products are delivered as GeoTIFF files.
