1674 – Ignace Revell Batholith LiDAR Survey – Final Report

Figure 4 shows the estimated solar angle during the acquisition window, with a solar angle of 27° at the beginning of the acquisition window, a maximum angle of 33° 18:00 UTC and 22° at the end of the acquisition window. [...] The low standard deviation in the height profile, as seen in Table 9 indicates a quality aerial survey acquisition process as changes in height effect the resolution of the imagery and the density of the LiDAR point cloud. [...] The tiles were saved as ASCII and XYZ files for the DEM and DSM and www.atlisgeo.com Down to Earth Information 14 FINAL REPORT 1674 - IGNACE REVELL BATHOLITH LIDAR SURVEY Nuclear Waste Management Organization as LAS v1.4 for the point cloud; each tile was named according to the UTM coordinate in the southwest corner of the tile. [...] Because ATLIS was unable to access most of the project site, a point was computed from the LiDAR data at the corner of the waterbody, shown in Figure 17, to serve as a third GCP for the aerial survey. [...] Weaverbird ran an ortho-rectification process on the photos using a combination of the EO parameters estimated in the AT process and a bare-earth surface model generated from the classified LiDAR data to remove the effect of perspective from the imagery.
