Re: AI-GEOSTATS: point-elevation-kriging
Thank you for your clear description of your problem.
Your data is irregularly spaced. Your 'natural'
interval for lag would be the closest inter-contour
Lognormal universal kriging seems to be the obvious
answer to your kriging question. The back transform
for lognormal kriging with trend has been validated by
top experts such as Noel Cressie, since 1998.
If you need to assess the 'uncertainty' or confidence
on your maps, lognormal sequential simulation is very
simple on this basis.
