<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 <span style> </span>classification grid for contaminated soils. </span></p>
<p class="MsoNormal"><span style lang="EN-CA"><br>
</span>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 <span style> </span>in order to transpose the it on the limits of
locations <span style> </span>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.</p>
<p class="MsoNormal">If Grass doesn’t implement this algorithm is there any
method using kriging to perform this kind of work?<br>
<br>
By searching on the subject, I found that only Geostatistical Analyst ESRI in
recent versions include this method. Am I wrong?<br>
<br>
Thank you for any help, cue and ideas for reaching our goals.</p>
