I have a feature class in a file geodatabase that contains three subtypes. When I use the Get Data for ArcPad button and set the Action to Checkout for Disconnected Editing | Data Based on Defined Extent ArcMap crashes every time. I've tried this in ArcMap 10.1 and 10.0. I understand that subtypes are compatible with ArcPad.   Anyone have any ideas? David Sinton ... View more

I am attempting to use Arc Hydro to produce subwatersheds and can't get past the DEM Reconditioning step. When I run it I get this error statement:[INDENT] Making buffer constant grid .. Making smooth constant grid .. Making sharp constant grid .. Computing smooth drop/raise grid .. ERROR 010316: Unable to open the input raster: C:\USERS\DSINTON\APPDATA\LOCAL\TEMP\9\ARCC13E\AH2013~1\G_G963 ERROR 010067: Error in executing grid expression. Failed to execute (DEMReconditioning). [/INDENT] I have full read / write access to that temp directory and every directory along the way. The above error is produced when I use the Arc Hydro toolbox but it still fails if I run DEM Reconditioning from the toolbar. I am using ArcGIS 10.1 thru a Citrix XenApp interface. Arc Hydro 10.1 (April 29, 2013) is installed. Interestingly, when I look in that temp directory there are no grids by that name (G_G963) but there are files with that name. Could this suggest that Arc Hydro attempted to build temporary grids but failed? What am I doing wrong? David Sinton ... View more

I'm upgrading a python script so that it'll function in ArcGIS 10.1 and as such I have the opportunity to change the raster format. Currently, the rasters are saved in Esri's grid format which has a few drawbacks. The most notable one is that grids cannot be stored in a directory structure with more than 120 characters (including the name of the raster). I believe this is no longer the case starting with 10.0; is this true? Also, what is the most efficient raster format when using Spatial Analyst? Is it Esri's Grid, Erdas' IMG, or storing them in a file geodatabase? Efficiency, I'm defining here as the fastest processing time but I'm also concern to a lesser degree with storage size. The output from these steps will be single-band and either integer or float. David Sinton dsinton@blm.gov ... View more

In ArcGIS 10.x ESRI introduced the concept of default geodatabases where output from geoprocessing tools would automatically go unless directed otherwise. The location that ArcGIS chooses for this default geodatabase doesn't fit the needs of our organization. I'm wondering if one can change the location of the default geodatabase and the home folder too by using Python. I'm somewhat experienced in scripting with Python but I can't find anywhere in arcpy that allows one to make this change. Does anyone out there know how to script this? Thanks, David ... View more
