Laser altimetry data from the NASA IceSAT spacecraft is used to compute x, y, and z offsets for ArcticDEM strip files. The values of these offsets are contained within the DEM metadata, but are not applied. How can I apply these altimetry-derived offsets myself? Solutions using Python / GDAL are ideal but I am really just looking for the logic.
An example metadata file and translation vector:
DEM Filename: WV02_20160702_10300100590AAE00_1030010058954200_seg1_2m_dem.tif Registration Dataset 1 Name: GLA14_rel634 GCP Month Range (+/- months)=1 # GCPs=563 Mean Vertical Residual (m)=0.004 Median Vertical Residual (m)=-0.003 Translation Vector (dz,dx,dy)(m)= 1.213, 0.366, 0.097 Vertical Deviation Percentiles(m): 50th percentile=0.340 55th percentile=0.372 60th percentile=0.417 65th percentile=0.462 70th percentile=0.519 75th percentile=0.580 80th percentile=0.640 85th percentile=0.741 90th percentile=0.849 95th percentile=1.043 100th percentile=5.235
