Hello, I like to know if Grass has the Areal Interpolation method based on the kriging model . I'm working on a project for which we have data on the volumes of contaminated soils. This volumes are represented by polygons data containing estimated volumes for 4 variables used from Quebec Environment Ministry classification grid for contaminated soils.
However, we do not have data that characterize the whole metropolitan area and we would like to experiment the Areal interpolation method based on kriging to generate grid volumes interpolation in order to transpose the it on the limits of locations where any characterization have been performed. We have delineated location for the entire metropolitan area where data for which we want to have the volume of contaminated soils. If Grass doesn't implement this algorithm is there any method using kriging to perform this kind of work? By searching on the subject, I found that only Geostatistical Analyst ESRI in recent versions include this method. Am I wrong? Thank you for any help, cue and ideas for reaching our goals. Regards
