2499RE: [ai-geostats] cokriging by using GSLIB
- Apr 6, 2006Hi Feng,
Indeed, you need to create a single file with the two variables
combined and use a "missing value code" (i.e. below the trimming limit)
at all locations where only one of the two variables have been measured.

Subject: [ai-geostats] cokriging by using GSLIB
I was trying to use cokriging to estimated soil N content while using NDVI as a secondary variable. I am confused of how GSLIB arrange the variables. Since I have more NDVI values than soil N values, Should I put both variables in one datafile ? If not, how to arrange that?
Thanks a lot
