mdsumner commented 3 years ago

now in latest raadfiles, just need to record what happened: 

gdalwarp ./data/www.bodc.ac.uk/data/open_download/gebco/GEBCO_15SEC/zip/GEBCO_2019.nc 
 .. data_local/aad.gov.au/gebco/GEBCO_2019.tif  -co NUM_THREADS=28 -s_srs "OGC:CRS84" -te -180 -90 180 90  -co BLOCKSIZE=512 -co BIGTIFF=YES -ot Float32 -t_srs  "OGC:CRS84" -of COG

COG doesn't compress by default ...

gdalwarp .. data/www.bodc.ac.uk/data/open_download/gebco/GEBCO_15SEC/zip/GEBCO_2019.nc .. /data_local/aad.gov.au/gebco/GEBCO_2019_lzw.tif  -co NUM_THREADS={} -s_srs "OGC:CRS84" -te -180 -90 180 90  -co BLOCKSIZE=512 -co BIGTIFF=YES -ot Float32 -t_srs  "OGC:CRS84" -of COG -co COMPRESS=LZW

mv GEBCO...lzw.tif GEBCO....tif ## etc

gdaladdo .. /data_local/aad.gov.au/gebco/GEBCO_2019_lzw.tif -minsize 512 -r average

ok trying this now

gdalwarp ../data/www.bodc.ac.uk/data/open_download/gebco/gebco_2021/zip/GEBCO_2021.nc ../data_local/aad.gov.au/gebco/GEBCO_2021.tif  -co NUM_THREADS=28  -co BLOCKSIZE=512 -co BIGTIFF=YES -co COMPRESS=DEFLATE -ot Int16 -t_srs  "OGC:CRS84" -of COG -te -180 -90 180 90 -ts  86400 43200

overviews are AUTO for COG profile so no gdaladdo needed
