Hi r-sig-geo list,

I'm trying to do space-time interpolation of temperature from satellite
datasets. To start with, I am planning to start the ST interpolation using
a daily one-week  data. Right now, I already converted the data set into
ASCII and read it using rgdal to create SpatialGridDataFrame object. I know
that I need to 'convert' it into STFDF for variogram analysis, etc.

I just wondering whether I am on a right track. Would that be an option to
stack my satellite images and then convert it into STFDF?

Which step is better?
