Mike You could also try the following; - open the Reclassify GP tool dialog and select your input raster - hit the Classify... button (to the right of new values) - on the Classification dialog, hit the % button (far left of Break Values) - now you can drag the blue vertical lines to choose your top % (i.e. 10000 is what % of number of cells in your raster?) - hit OK, and OK agian to do the Reclassify Now you have a integer raster and you know what value represents the top 10000 values - use the Con tool   - Input conditional raster = integer raster you created above   - Expression, hit the SQL button and create the "where clause", viz., "Value" = the value that represents the top 10000   - Input true raster = your initial input raster   - Hit OK Cheers Steve ...

Eric Have you looked at the Crossvalidation geoprocessing tool? and also the GALayerToPoints gp tool. As far as the blank screens go, I'm afraid I cannot help you. Please contact Esri Support. You may also want to look at http://blogs.esri.com/esri/arcgis/2012/05/07/dealing-with-extreme-values-in-kriging/ Steve ... View more

Eric Does the green progress bar at the bottom of the dialog go all the way to the right when exporting the cross validation results ? I tried to repro what you did but cannot repro the "no output" to fGDB or pGDB Thanks Steve ... View more

Shaina SplineWithBarriers in 3D is identical to the SplineWithBarriers in Spatial Analyst. I tried to reproduce what you outline, however, my output rasters do snap and are identical. Please can you contact Esri Support so that they can log an incident. I'm not sure what you mean by this. Hi- I also noticed that a dialog box comes up when the Spatial Analyst version is used, but not when the 3D Analyst version is used. I attached an image of what's happening. Hope this helps.

Gregory There is a problem with the way that TopoToRasterByFile treats paths and feature class names that have spaces. Here is the "bug" number for future reference. NIM080744 TopoToRasterByFile throws ERROR 010134 Input does not contain a feature class. when the path to an input feature class has a space or input feature class name has a space. Sorry for the inconvenience. Steve ... View more

You have a few options. #1 Directly on the geostatistical layer - right click the geostat layer then Validation/Prediction, or - directly use the GALayerToPoints tool #2 Once you've exported the geostat layer to raster, then use any of the following geoprocessing tools - SAMPLE - ExtractValuesToPoints Steve ...

From the help (http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//00310000000s000000.htm) If the interpolation model you build uses one of the kriging methods, and you choose to transform the data as one of the steps, the predictions will be transformed back to the original scale in the interpolated surface. If you transformed the data within the Wizard then a back-transform is automatically applied. -Steve ... View more

Dean Please zip it and send it to slynch@esri.com Thanks Steve ... View more

Dean What do you mean by changed? Can you give a before and after example? Also remember that the raster will be 32 bit floating point precision if your as using the FLOAT option. This means that not all values can be represented exactly. 1.3 for example is represented as 1.2999999523162841796875E0 Hope this helps Steve ... View more

Anna You can use SetNull or CopyRaster. However, NoData values are treated as Nulls and are ignored in calculations and operations. Steve ... View more

Gary Is it the interactive contour tool on the 3D or Spatial Analyst toolbar that you are saying is slow? If that is the case, please install Service Pack 4. We changed the interactive tool to rather work on display resolution so it'll be much faster. Steve ... View more
