Help with Kriging

BrookMitchell — Tue, 03 May 2011 16:20:02 GMT

I am just getting started utilizing ArcGIS 10 for analysis of soil EC/pH data. I ran a Kriging operation for a field (EC data) @ 18.29 meter cell size and I have an area west in the field that has a blank area (so not getting all of the field krigged. See attached jpg. How do I get it to run x% past the area, so I can clip it later to the field boundary?

Right click the Geostatistical Layer -> Properties -> Extent, then choose an extent

I went to the Kriged EC layer, right clicked and changed the extent to rectangular extent of field boundary -> apply -> ok. Unfortunately it didn't change and when I go back into the extent properties, it is right back "to current setting of this layer".

Is this a Geostatistical layer?
Is field boundary's extent larger than the extent of the points?
Try choosing "the current display extent"

Steve,
I'm sorry for the stupidity here, but I'm used to the ag world of shapefiles and point data. What is a geostatistical layer and how do I check this it out? As for the field boundary being wider than the put data_ yes. If you look at the jpg you can see the yellow boundary is outside of the data pts.

It is a layer created using the Geostatistical Analyst extension. If you created the output running Spatial Analyst or 3D then you'll need to specify a larger processing extent in the Environment and re-run the tool.

Hope this helps.
