Hi Antilla Perttu and the gstat users
looks as if there are no repls to your mail Antilla Perttu or I missed it.
Well, I had the same problem with an e00 file and didnt managed it either.
My solution was to write a small tool that cuts my dataset into pieces
which I than used to feed gstat. I combined it with coordinate ids
from the subsetting procedure (center coordinates of the subsets) - and
the outcome is something like a segmentation with gstat estimate
attributes. I works fine for me but the e00 approach is still on my
list. The interesting point for you: I am
doing the whole thing for forestry as well and with highres digital stereo
scanner data (HRSC-A Data) for forest stand structure attributes.
If there is someout out there that has experience with the e00 integration
with "edges: '*.e00' ...
I would also very much appreciate a helpfull hand in that respect :)) .
All the best.
