Hi Benjamin, As far as soils data, we would probably often mask with depths min or max, use a plan to cut the profile collection to return points (give the carbon value at 13.5cm depth for this collection of profiles). Alternatively, we would try to interpolate a profile collection to harmonise

Hi Ben, All that I meant by mask is, in this case, an r3 map that defines a subset of space that subsequent operations are constrained to. I guess I was just expressing worry about creating runaway data demands.The region settings act as a three dimensional bounding cube, does not seem adequate

Hi Tim, i am the second mentor in your SoC project, and will try to help you with the 3D raster approach in GRASS. The 3D raster implementation in GRASS is using a tiled based storage approach.[1] The tiles can be stored in compressed form (zlib in GRASS7) or uncompressed form on the hard disk.
