[GRASS-user] Vector to 2D Raster

[Francois Chartier]

Here is the error message that i get: 

v.vol.rst input=BHMat1All at Toronto dmin=0.5 elevation=may11                      
ERROR: Unable to get layer info for vector map
(Sat May 12 14:46:07 2018) Command finished (0 sec)      

I am not sure what ‘Layer’ info is this referring to. I have 4 columns, X, Y, Z, Property (numerical). 70,000 points all together.

Francois

Good hint - I have added above to this section:
