I have downloaded a certain tile from https://www.eorc.jaxa.jp/ALOS/en/aw3d30/data/index.htm, and after the requisite logistics (unzipping, putting all *.AVE_DSM.tif files into a single folder), I built a virtual
dataset with gdalbuildvrt *.tif asia.vrt.
Now gdalinfo asia.vrt gives this:
Size is 108000, 90000
Coordinate System is:
GEOGCS["WGS 84",

Pixel Size = (0.000277777777778,-0.000277777777778)
Corner Coordinates:

Band 1 Block=128x128 Type=Int16, ColorInterp=Gray
I can query the data as follows:gdallocationinfo -geoloc asia.vrt 110.00 30.00, meaning "Find the elevation
of the point at 110 degrees East and 30 degrees North",
and get a proper
Report:
Location: (72000P,72000L)
Band 1:
<LocationInfo><File>N029E110_AVE_DSM.tif</File></LocationInfo>
Value: 894
Now I would like to project the entire region I've got here
to a rectangle P = [a,b]x[c,d], so that I can query not with lat/lon pairs but
rather with a point from P. Naturally, I need the distance
between the two points be somewhat reflective of their "original" distance.
I do not care much about the specific values of a,b,c,d, and anyway I think
they depend on the units option we would supply to gdalwarp.
Now my question is,
what is the exact gdalwarp-command I need to issue to accomplish this?
I know it has to do with proj-string, but I am lost to its multitude of parameters.
