[GRASS-user] Reprojection regions

[Rich Shepard]

I used r.proj for a raster map. Part of the output includes these:
Input:
Cols: 46742 (original: 46742)
Rows: 18655 (original: 18655)
North: 5058076.050000 (original: 5058076.050000)
South: 5039421.050000 (original: 5039421.050000)
West: 537042.640000 (original: 537042.640000)
East: 583784.640000 (original: 583784.640000)
EW-res: 1.000000
NS-res: 1.000000

Output:
Cols: 47260 (original: 168219)
Rows: 20128 (original: 117314)
North: 40028.627671 (original: 121849.848538)
South: 19900.573338 (original: 4535.531862)
West: 341691.218417 (original: 220732.502481)
East: 388951.107430 (original: 388951.107430)
EW-res: 0.999998
NS-res: 1.000003

I assume that the number of cells
and the corners of the region are those for the source and target
projections, but to what do the 'original' values refer? Is this
information on a manual page?

TIA,

Rich
