How many features are there in the 10th feature class?, viz., in F:\PC-LAB_abr12\Shapefiles\SAD_69_Polyconic\LitoralBrasil_PCS.gdb\Litoral_Brasil_1\Lut_ana_1 Risk_rank you can use GetCount or open the attribute table. What happens if you run PolygonToRaster GP tool using this feature class ? Thanks Steve ... View more

Jamal It is often better to cite a reference rather than copy from it. This will give you more insight into the inner workings and assumptions around these equations. Which is what we have done for IDW and Kernel Density. Steve ... View more

Jamal A search would have led you to a thread Dan participated in 7 years ago, viz., http://forums.esri.com/Thread.asp?c=93&f=995&t=176542 What are the problems that you are seeing? Steve ... View more

Al These (explore data>semi variogram) are part of the ESDA tools. The point cloud will consist roughly of 4000*4000/2 points (8 million points). I'll be too dense to get any meaningful info from. You did see the warning message that came up when you tried to process the 4000 points? I would suggest that you rather take a subset of your data (use the SubsetFeatures tool). I would suggest no more that 500 points. The 4000 points will be fine to use when doing kriging though. Steve ... View more

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.

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 ...
