[Qgis-developer] SAGA kernel missing CRS?

[Victor Olaya]

Ok, i tested with your CRS definition and it works fine

I create a shapefile and add that CRS definitino in a prj file. I open
that file and the CRS is correctly identified as EPSG:27700 - OSGB
1936 / British National Grid.

Then I calculate kernel density, and the output sdat file has a prj
file with exactly that same CRS definition (this is what the fix that
i added does, just moving the CRS definition from  input to output).
Can you check that it is not happening like that in your case, opening
the prj file of the sdat file and comparing?

Computing contour lines with the density layer works as expected, also
using the same CRS definition.

Cheers
