One way would be to iterate through some power values and use the CrossValidation tool to get the RMSE value. The power value associated with the lowest RMSE is the optimal power value. ... View more

Why not use CellStatistics with the ignore_nodata option. Steve ... View more

These are interpolation method dependant. IDW, for example on has error. Kriging has many more. Steve ... View more

Please check the help, below is a snippet from IDW's help. Some input datasets may have several points with the same x,y coordinates. If the values of the points at the common location are the same, they are considered duplicates and have no affect on the output. If the values are different, they are considered coincident points. The various interpolation tools may handle this data condition differently. For example, in some cases the first coincident point encountered is used for the calculation; in other cases the last point encountered is used. This may cause some locations in the output raster to have different values than what you might expect. The solution is to prepare your data by removing these coincident points. The Collect Events tool in the Spatial Statistics toolbox is useful for identifying any coincident points in your data. Steve ... View more

William What version of ArcGIS are you running? Please set your current and scratch workspace to a location where you have write access to. What format is the raster in, fgdb, grid, tif, img or ? What format are you writing to ? (shapefile, fgbd, ?) Can you try with grid input and shapefile file output ? Thanks Steve ... View more

Once you have exported the shapefile featureclass to file geodatabase do the following use either SelectLayerByAttribute_management or management.MakeFeatureLayer selecting all values = -9999 then CalculateField(�??mylayer�??, �??FieldZ�??, �??None�??, �??Python�??) Steve ... View more

Can you try it without altering the Output Extent values, i.e. leave the default extent. Thanks Steve ... View more

Use Point To Raster, but then only the areas around points will be converted, or make the cell size very very small, but this will not be practical, or shift the input locations. Why do the values have to be the same as the interpolated cell values? Steve ... View more
