I'm trying to use FWTools to transform from an arbitrary Datum/Projection
pair in an arbitrary format into a Geographic (lat/lon) projection with the
WGS84 ellipsoid in GeoTiff format.
To do this, I've tried the following:
gdalwarp -s_srs Input.prj -t_srs Output.prj Input.xyz Output.tif
Where Input.prj is formatted in Well-Known-Text format and contains
information specifically for the Input.xyz file.
Output.prj is also in WKT format but contains the following:
I've been successful in using this set-up for transforming from UTM
projection in WGS84 datum, but I am having trouble transforming from
Sinusoidal projection in RT90 datum. The output file is no longer skewed in
the Sinusoidal projection, but I cannot seem to get the datum information to
coincide, resulting in a 10+ km discrepancy.
A copy of the WKT-formatted PRJ file is seen below:
Any ideas as to why I would be experiencing this offset?
