Hi,
When trying to reproject a raster projected in UTM (WGS84) to Oblique Mercator (WGS84) I get this message:
Unable to initialise PROJ.4 with the following parameter list:
+proj=omerc +lat_0=45.1875000000 +lat_1=-20.0000000000 +lat_2=20.0000000000 +lon_0=0.0000000000 +lon_1=-120.0000000000 +lon_2=-60.0000000000 +k_0=1.0000000000 +no_uoff +rot_conv +a=6378137 +rf=298.257223563 +no_defs +towgs84=0.000,0.000,0.000
The error message was ‘invalid projection system error (-1304680961)’
Can’t get projection key values of output map
The “Current Location” seems to have been set correctly so I do not see why I am getting this error.
Thanks in advance for any suggestions,
Garret.

The "Current Location" seems to have been set correctly so I do not see
why I am getting this error.
If I run the command-line "proj" program with those parameters, it
fails with a domain error, which suggests that the combination of
parameters is invalid for the projection.
Quickly playing around with the parameters indicates that it works
provided that the absolute value of lat_0 is less than 36 degrees.
Beyond that, you might do better asking on the PROJ list for issues
with specific projections.
