Thanks Hamish and Facundo! I will give a try to the updated v.surf.icw soon ;) If I find some time I will try a python porting anyway, as a personal exercise with the new grass7-python facilities.
Thanks Facundo, I was also looking for similar implementations with kriging. The same for icw, I will read and have a look to the code you shared ASAP. giovanni 2011/12/7 Facundo Muñoz <[email protected]> > I have implemented a while ago a cost-based kriging that I used exactly > in that way. > You can see the paper and sample code here: > http://www.geeitema.org/guenmap/index.jsp?opcion=resultados&idioma=en > > There is a GRASS script that helps to compute the cost-based distances, > and then there is an adapted geoR library that performs the cost-based > kriging computations. > > Let me know if you need help in applying it to your case. > ƒacu.- > > > El mar 06 dic 2011 18:11:52 CET, G.
