1661GEOSTATS: interpolation with obstacles
- Oct 4, 2000Dear group,
I am currently struggling with an interpolation problem dealing with
obstacles and I would like to get advise from more experienced persons.
Data : 8 000 answers to a survey corresponding to roughly to 4000 postal
Goal : interpolate these answers over the Island of Montreal (500 sq.
km) in order to produce a grid allowing further analysis.
Problem : interpolate the answers only in specific land-use polygons,
taking into account holes and not compatible land-use polygons for the
I have to use VM but it does'nt seem to take into account such obstacles
in its calculations. All it seems to be able to do is mask the results
with the undesirable polygones. Someone told me about gstats, but can it
solve this problem ?
A truck load of thanks,
