[Qgis-user] Projection

[Otto Dassau]

Hi Werner, 

I tried to find your raster file projection "UTM_WGS84_M15", but it doesn't seem
to be available. What happens if you create your own CRS in QGIS. From your .prj
file this should work:

Setings -> Custom CRS

Name: UTM_WGS84_M15
Parameters: +proj=tmerc +lat_0=0 +lon_0=15 +k=0.9996 +x_0=500000 +y_0=-5000000
+ellps=WGS84 +units=m +datum=WGS84 +no_defs

Then you load the raster, which is projected in "UTM_WGS84_M15", choose your
custom projection in the Project Properties dialog, select "Enable OTF" and
load the shape. The vector should now fit with the raster.

 regards,
  Otto
