[GRASS-user] gdal_warp

[goldneaa at onid.orst.edu]

I have unprojected Geotiff data that I am trying to put a projection  
using gdalwarp.  My input is

gdalwarp -s_srs epsg:26910 -tps -t_srs epsg:2766 ts_1870.tif proj_1870.tif
When I try to convert I get the error.

ERROR 1: Unable to compute a transformation between pixel/line
and georeferenced coordinates for ts_1870.tif.
There is no affine transformation and no GCPs.

I am trying to plug in more flags from the gdalwarp help page, to  
understand GCPs, but I have had no luck.
