[Gdal-dev] Gdalwarp Error: unable to compute a transformation between pixel/line and georeferenced coordinates for sourcefile

[John Mitchell]

Hi,

When trying to run the following:
gdalwarp -s_srs EPSG:4269 -t_srs EPSG:4326 -rc -of HFA sourcefile destfile
I get the following error:
Error 1: Unable to compute a transformation between pixel/line and
georeferenced coordinates for sourcefile.  There is no affine transformation
and no GCP's.

When running gdalinfo no coordinate system is listed but I was told it is
NAD83, also I was also given a .sdw file in addition to the .sid file

gdalinfo below:
