    Kriging Extent Problems


      I'm working with the geostatistical wizard and having issues getting kriging predictions to extend throughout my study area. Currently, I'm working with a point file for California, and though the points are distributed throughout a large portion of the state, they do not extend to the N/S and E/W borders of the state, leaving a few areas without observations. When I run a kriging model with these data, the output extent is a polygon that covers only the area between the furthest north and south points and between the furthest east and west points, leaving out a fair amount of the state. I understand the logic behind the extent I'm getting as an output, but I still need a kriging surface that includes the areas currently left out of the calculation. How do I get this? I've tried going through the geoprocessing environments and editing my processing extent, but have had no luck.

      Any tips?  Perhaps I'm missing something obvious...
