Amazing! If you data represents a property (K) that is given for the top
elevation (Z) at which it is identified in the database.
With v.vol.rst, are you able to assign that property downwards until the
next property value.
For example, in the example on the webpage, there is a 3D raster for soil
moisture; if the soil moisture is measured only for the top of a cylinder
along your vertical hole, the next moisture measurement is taken at a lower
depth, and the intervals (cylinder length) are not the same along that
