<div dir="ltr"><div>Hi,<br><br>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. <br>
<br>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 for generating grid volumes interpolation in order to transpose it on the limits of locations where none characterization has been performed. We have delineated sectors for the entire metropolitan area with data for which we want to have the volume of contaminated soils.<br>
If Grass hasn't implemented this algorithm, is there another way using kriging to perform this kind of task?<br>By searching on the subject, I found that only Geostatistical Analyst of ESRI in recent versions include this method. Am I wrong?<br>
<br>Thank you for any help, cue and ideas allowing us to reach our goals.<br><br>Regards<br><br></div>Tahir<br></div>
