In 10SP1 we fixed it so that Raster To Polygon with all NoData will throw ERROR 010151: No features found To test if a Raster has all NoData run the IsNull tool. If the output is all 1 then it only has NoData Steve ... View more

Abby It is a 3 step process 1) arcpy.SelectLayerByAttribute_management('ca_ozone_pts', 'NEW_SELECTION', '"ELEVATION" = -9999') 2) arcpy.CalculateField_management('ca_ozone_pts', 'ELEVATION', 'NULL', 'VB', '#') 3) clear the selection or save the layer to a new FC in a file geodatabase Steve ...

Abby If you rather store your feature classes in a file geodatabase then <nulls> are supported, i.e. ignored. Else, leave the -9999 values and do a selection prior to using the Wizard. Steve ... View more

Chris Have you looked in the help? http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/Set_Model_Parameter/00300000001m000000/ Regards Steve ... View more

Andrew Persist the Join (i.e. CopyFeatures to new FC), can the field be used? Does IDW work? Can your use one of the joined fields to do Buffer (i.e. use your joined field in the Field control)? Thanks Steve ... View more

The points are not multipoint are they? If not, could you zip the points and email them to me ([email protected]) Thanks Steve ... View more

We changed our searching neighborhood algorithm for ArcGIS 10. It appears that this is the cause of your speed issue. We made it more robust but appears that in your case it slowed down the process considerably. We�??re looking into fixing it. However, if you change the Sector type to 1 sector it�??ll be fast or you could also keep the 4 sectors but change the minimum neighbors to 0 and it�??ll be fast. The data that Bryce has is very densly sampled and the change of neighborhood will therefore not impact the predictions. Hope this helps Steve ... View more

Bryce Could you pachage the GA layer (in the following toolset, DataManagement->Package) and post it to the Forum or email it to me ([email protected]) also, please let me know the cell size and raster format (grid or fGDB or ?) that you are exporting to. And, BTW, do you have any geoprocessing environments set, i.e analysis cell size, extent, snap raster, output coordinate system? And, BTW, the GALayerToGrid geoprocessing tool is the same that is used when right clicking on the GA layer and choosing Data->Export... Thanks Steve ... View more

Please can you contact Esri Support. Thank you Steve ... View more

Raster to Polygon only takes integer (or string) - period. This is by design since 9.0 The reason is that too many individual polygons will be created in most cases. In the case where one really wants float output, then can multiply the raster by, say 1000, and cast to integer, convert and then divide by 1000. This workflow has been repeated many, many times in this Forum. Steve ... View more

Can you run Spatial Analyst's IDW with the data, output cell size and output location and raster format? Thanks Steve ... View more

Please try to narrow down the problem, viz., - use a smaller dataset, with and without a barrier - output to ESRI grid rather than fGDB - create a new fGDB and output to it - with you posted scenario, increase the cellsize and exclude the barrier and output to ESRI grid Please let us know which of these are successful.

Please have a look at the links that Eric provided earlier in this thread for a reference as to where it is documented. If you cannot add the 5x5 file then please contact Esri Support. -Steve ... View more

It must be greater than 2 by 2 Please try it with a 3x3 or larger raster Steve ... View more

The "ASCII" raster format is a supported raster format. Which means that if the file has a .asc extension it can be used directly. Which means that you can use the CopyRaster tool to change and set the output bit depth. Steve ... View more
