Re: Markus,
Having created a DEM of the depths for the bottom surface and used the outline as the top again, r3.out.vtk now gives me a 3D model in Paraview which seems to represent the DEM surface (including extrapolated height values outwith the lake, which I can solve when I get the Mask to work properly). Selecting to view the model as a Volume throws up the error message:
“Cannot volume render since no point (or cell) data available.”
Creating the file again in r3.out.vtk, but this time with some of the carbon data included as a G3D map, creates the same structure, which resembles voxel form. However, selecting to view it was a Volume starts a loading process which takes over 3 hours (I still haven’t seen it finish yet!), with the message ‘OpenGLProjectedTetrahedraMapper’ at the bottom and a loading bar which goes from 0 to 100 then starts again on a loop.
Using v.vol.rst with the carbon data, I used this command line:
“v.vol.rst input=Seasonal_0411_DIC@PERMANENT wcolumn=dbl_3 elev=G3D_0411_DIC_2707”
This produced the error message:
“ERROR: Key column type is not integer”
The info for the Carbon file is as follows:
“v.info -c Seasonal_0411_DIC
INTEGER|cat
DOUBLE PRECISION|dbl_1
DOUBLE PRECISION|dbl_2
INTEGER|int_1
DOUBLE PRECISION|dbl_3
Displaying column types/names for database connection of layer 1:”
The carbon data is contained within dbl_3, with dbl_1, dbl_2 and int_1 being the x/y/z coordinates.
Re: Hamish - Thanks for the advice. I’ll try those modules out today.
