1 Gdalwarp is something of a pain. I got decent results with: | |
2 | |
3 gdalwarp -r lanczos -srcnodata None -dstnodata None -multi -tr 1 1 WA_Hamilton_20200305_TM_geo.tiff WA_Twin_Sisters_Mountain_20200323_TM_geo.tiff both.tiff | |
4 | |
5 Note that this changed the resolution (roughly doubled it, in fact). | |
6 There does not seem to be a good, easy way to tell it to preserve | |
7 resolution. You must play with -tr. Anything higher than 1x1 is nasty | |
8 and coarse. Anything less gobbles disk space exponentially. |
