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

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
