Dan Spaces should be OK from version 10 on-wards. In most cases the tool will throw an appropriate error or warning, for example, a field name in a fGDB that has a space will cause the following to be thrown; The field name that you intended to add to your feature class or table is invalid and has been modified accordingly. Using invalid characters within a field name, such as spaces, are a common cause of this error. If you come across any please contact Esri Support. Thanks Steve ... View more

NIM063257 - PolygonToRaster - output cellsize and extent values do not have decimal values in comma locale when input cell size has decimals (only with grid output) , in ArcGIS10 SP2, fixed this problem. If you install SP2 or later, does it fix your problem? Steve ... View more

Brent Are you talking about the enhancement that went into ArcGIS10 which was released in 2011? See http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/Cell_Statistics/009z0000007q000000/ -Steve ... View more

Giacomo We need to see all the errors that the IDW tool throws. And could you zip the feature class and attach it to this thread? Thanks Steve ... View more

Any special reason why you would want to use kriging on lidar data? Kriging will take forever when you have a large number of points and it may never finish. I would suggest you look into less memory intensive interpolators. Kernel Interpolation (with Barriers) in Geostatistical Analyst is an example of one that I have used with roughly 4 billion input points. Steve ... View more

What version of ArcGIS are you using? The Geostatistical Wizard does not output a raster, it creates a geostatistical layer which you can convert to raster, polylines or filled polygons. If you did kriging via the toolbox it means that you used the Spatial Analyst (or 3D) version. How large is the output raster? Have you tried converting the HUC10 layer into raster and use that in ZonalStatistics? - Steve ... View more

I do mean CellStatistics and a major update was made in ArcGIS 10 to control the handling of NoData, see http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/Cell_Statistics/009z0000007q000000/ and in particular the section on ignore_nodata Steve ... View more

Giacomo Please contact your local distributor or Esri Support. Also try turning off "background processing", this can be done via Geoprocessing -> Geoprocessing options and then uncheck the background processing option. The reason I suggested that your data are corrupt is based on the fact that I (nor you) could open the point feature class that you provided me. Steve ... View more

To better understand the problem could you please provide me with a copy of your input data, the interpolation parameters (i.e. a screenshot of the filled out dialog). If you do not want to post it on the Forum you can email me ([email protected]) Thanks Steve ... View more

April The default extension in the RasterToASCII GP tool is .txt, however, you can also use .asc These are the 2 extensions to use. If you create it using the .asc extension then it becomes a supported raster data format, i.e. you can use it in ArcGIS as any other raster dataset (no need to then use ASCIIToRaster). Please can you share a screenshot of the dialog or are you doing it via scripting. Thanks Steve ... View more
