Geoprocessing Kriging

AndrewWindham — Thu, 08 Jan 2015 15:02:34 GMT

Hello

I am trying to take a point data file of soil phw values
from soil samples taken in the field and automate the process of kriging using
model builder in ArcGIS 10.2. First I need to run the kriging analysis using
geostatistical analyst. Secondly I need to export the kriging into a raster
format and clip the boundaries of the raster to a field boundary shapefile and
then send data to mxd with predefined coordinate system and legend and if
possible text that can be changed when needed. Is this possible using
modelbuilder?

Thanks for any help one can provide!

For the kriging step, you should probably use Empirical Bayesian Kriging (EBK). It is our most accurate interpolation method, and it is easy to automate because it is available as a geoprocessing tool (it can also be accessed from the Geostatistical Wizard). You'll want to output a raster and set both the Extent and Mask environments to your boundary shape file. You can also use the Output Coordinate System environment in EBK to define the spatial reference of the output raster.

I'm not sure how to do the rest, but hopefully someone else can help with those parts.

Thanks for the help Eric

I am having issues with something else in ArcGIS as well. I have created a custom color ramp in a geostatistical analyst layer and also have created custom unique value ranges that were created manually to go with the symbology. Because this was created in a GA Layer importing the symbology into the raster layer will not work. Also I can not figure out how to input custom unique ranges using classified symbology in a raster. I am stumped any help would be appreciated.

Thanks
