Andrea, Do you have ArcGIS Desktop 9.3, or 9.3.1? The ArcHydroTools9.msi installer (build 1.4.0.258, Jan 9 2013) on the secure download site will install and run for either release of ArcGIS. Once you install, the ArcHydro Tools Help article will take you through the map algebra processes ArcHydro Tools perform for conditioning the DEM (filling sinks), and identifying flow direction, flow accumulation, stream network and/or basin,  and finally raster to feature conversion. Also, the ArcGIS 9.3/9.3.1 Spatial Analyst help, has some guidance. But is a bit disjointed and out of sequence compared to the Help presentation in ArcHydro Tools, and be sure to review the "Learn more about..." Help panels as well. It will work, but the data handling is a bit more demanding when using Spatial Analyst extension compared to ArcHydro Tools. Post back if still stuck. Stuart ... View more

Andrea, The ArcHydro Tools extension for ArcGIS 9.3.1 was developed and maintained by Esri Water Resources team and is still available for download from Esri's secure ftp site. It uses AGREE methods to characterize drainage. See this ArcHydro forum thread for login and download instructions: http://forums.arcgis.com/threads/82087-New-password-for-Arc-Hydro-ftp-site Make it easy on yourself and use a secure transfer program, I prefer FileZilla but there are others. Once installed, there are tutorials and exercise data and you can ask for help in either the ArcHydro or Hydro forums. Stuart p.s. If you really wan't to dig into the raster analysis methods, have a read of D. Nagel, J. Buffington & C. Luce on IDDEA (US Forest Serivce) vs AGREE (Esri - Hellweger/Maidment) methods in this talk -- http://www.fs.fed.us/rm/boise/AWAE/scientists/profiles/Nagel/Nagel_NWGIS2011_DrainageEnforcement_Compressed.pdf ...

Steve, We'll assume you have verified that the ArcMAP Customize -> Extensions -- Spatial Analyst checkbox is checked. If so, then give a a snapshot of your licensing: ArcGIS Administrator -> Desktop -> Availability panel. Looking for any indication of expired license date. Or, that any of the license are in an "untrusted state", indicating a corrupt FlexNet Publisher Trusted Storage license cache. Stuart ... View more

Matthew, As usual Richard has the right answer!  And likely the lmgrd and ARCGIS vendor daemons are both using TCP IPv4 port 27000, an edit the service.txt file as indicated should correct.

Tom, You appear to be running a 64-bit Enthought Python Distribution, dtd 4-12-2012 as you default Python. From your screen capture, the C:\Python27 directory listing contains a full Python distribution--python.exe, pythonw.exe which look by date to be the 64-bit EPD you show running in IDLE. Would likewise impact Python run from command prompt as your environment variables are pointing to that directory. But you also have an Esri ArcGIS 10.1 installation done on 5-9-2013. When, since the C:\Python27 would not have been detected as a 32-bit python installation, the Esri ArcGIS installer laid down the 32-bit Python in C:\Python27\ArcGIS10.1--a look in that directory will show you probably have another python.exe and pythonw.exe installed. Fortunately the Windows registry, ArcGIS for Desktop registry settings keep it pointed to the correct Python executables where it reads the Desktop101.pth for proper path actions. But since the system environment variables are pointing to the C:\Python27 directory, the 64-bit python is what is always being called from command prompt or Python IDE environment like IDLE. [INDENT]To clean things up, you should simply be able to uninstall the Enthought Python Distribution Free 64-bit Python from Add/Remove programs (appwiz.cpl). Then check your Environment variables to adjust the PATH value to reflect a path to "C:\Python27\ArcGIS10.1" and perhaps set a PYTHONHOME variable to "C:\Python27\ArcGIS10.1" Your IDLE session, or a windows command line or system scripted launch of Python, will then run with the 32-bit pythonw.exe[/INDENT] And, if you need 64-bit python, or want a packaged Python bundle like Enthought Canopy Express, you have to manage your environment adjusting it to use the appropriate versions. That would include use of Esri's ArcGIS 10.1 SP1 64-bit Desktop Background Geoprocessing installation when running it "out of process", i.e. without the ArcGIS Desktop GUI. The 64-bit Desktop Background Geoprocessing installation replaces some 32-bit components of the ArcPy site library with 64-bit equivalents--and the ArcGIS for Desktop does not use the system environment variables to keep track of the executable to run while in-process. But when running scripts outside ArcGIS for Desktop GUI, you have to manage the path and working directories for your 32-bit or 64-bit Python scripting. Hope that is clear enough for you, post back if not. Stuart P.S. not sure why your Windows 7 command line use of where.exe is not responding correctly with executable location, it should be. ...

Anton, Not sure what you had going on during those attempts, interesting in that your password was not passed. This snapshot from a recent valid connection: [ATTACH=CONFIG]25325[/ATTACH] Also, I've dumped out the my FileZilla Site Manager entry.  It is a .ZIP of an XML format configuration file.  Unzip it back to XML, and use the File --> Import button to load it into your FileZilla installation.

Tom, Sorry, I should have been clearer. Those are all Windows OS commands and utilities, just open a Windows command prompt (cmd.exe) window and enter each. Then copy & paste the result to a text editor to clean up for posting to the thread, or take a screen capture and post up the image.  Can see already though from you post, that you are launching a 64-bit Python--that will cause problems with 32-bit ArcGIS for Desktop.

I am using ArcGIS Desktop 10.1 with the HEC-GeoRAS 10.1 toolbar. What license of ArcGIS 10.1 for Desktop (Advanced, Stadard, or Basic), and have you applied SP1?  Do you have license for 3D analyst and have you activated it from its checkbox on the Customize --> Extensions panel? What source for the HEC GeoRAS beta toolbar? Current build is 10.1.0.23 (dtd 2013-02-28), what shows for it if you run "appwiz.cpl" from the run box? Stuart ... View more

Dan, Yes I beleive they are related, and we could use a look at the same set of environment configurations. Should we assume that your inprocess ArcGIS use of Python scripting is correct? Stuart ... View more

Copying this from the Geoprocessing forum as it has more complete details of Bhavna's installation... hi, I am bhavna using ArcMap9.3 with Windows 7 home basic 64 bit.
