thanks, i will try it in a little while and let u know. if i understand the principal, then it assumes the point is just further in distance for the interpolation but keeps the value at its original coordinate. to give more weight to a horizontal direction, the z scale needs to be increased

I thought Zscale was used to convert units ft to m, i didnt know it was for giving more weight to one direction. Le sam. 16 mars 2019 à 15:20, Benjamin Ducke a écrit : > On 16/03/2019 19:51, Francois Chartier wrote: > > Hi, > > > > Is it possible to add anisotropy when conducting interpolation

Hi, Is it possible to add anisotropy when conducting interpolation for 3D raster. I would like to give more weight horizontally than vertically in the 3D interpolation process. thanks, ___ grass-user mailing list grass-user@lists.osgeo.org

Dear all... I have this kind of data: two parallel lines of tomographic seismic profiles, that means (for who is not a geologist), that I have, along these lines, regularly spaced 3d points (like a vertical grid of points under the earth surface) each one having as an attribute a value of the P
