applying a regression kriging model outside gstats
Ordinary kriging and hence also RK are matrix algebra (http://spatial-analyst.net/book/system/files/RK5points.zip <-- look for the excel file). If you have model parameters (betas, vgm parameters), then it should be relatively easy to implement to generate predictions (you do not need gstat or similar). Problems might happen if the number of points is very high >>1000 so solving matrices can take time (in which case using a search radius etc is a good idea) or if you have to generate predictions for large areas... or you do not work with a linear model...

Hi, I have produced a regression kriging model using gstats that I want to deliver to a wide range of users to predict values for new sites using the web or as part of a simple computer software (e.g. Visual Basic software). Is there a simple way of doing that or do I need to use R and gstats to produce predictions? Many thanks Marc
