Hello,

This question is a bit off-topic, but related to what we need to do with GRASS:

We have a series of georeferenced .tif files accompanied by .tab files which look like this:

Definition Table
  File "s5_15 nw3_b-iii.tif"
  Type "RASTER"
  (513881,9523020) (1008,1098) Label "Pt 1",
  (519881,9523020) (10493,1111) Label "Pt 2",
  (519881,9517020) (10451,10523) Label "Pt 3",
  (513881,9517020) (990,10509) Label "Pt 4"
  CoordSys Earth Projection 8, 104, "m", 15, 0, 0.9996, 500000, 10000000
  Units "m"


However, gdal does not support the Mapinfo's CoordSys:
"only control points used, Coordsys ignored" (http://www.gdal.org/frmt_gtiff.html).

I guess that if we could transform these files into ESRI world files (http://www.gdal.org/frmt_various.html#WLD), we could import them easily with GDAL. But how to do this, as ESRI world files give transformation parameters, not points and projection info ?

Or is this the wrong approach ?

We can obviously easily import each file into an XY location and then run i.rectify on the basis of the available points, but I was wondering whether there is a better way.

Moritz
