ArcGIS 10.x tip! Overwrite previous outputs from geoprocessing

Do you need to geoprocess the same file again and again.  If only you could simply overwrite the old output file!  Do you end up with files like 'Clip', 'Clip1', 'Clip2'...when you only really need one file named 'Clip'?  Well, here's how to remedy all the duplicate files.  You can set up the Geoprocessing options to overwrite previous outputs.    

NOTE!  If you are person that likes all these copies, I don't recomend setting up the overwrite option.  You may accidentally lose data by overwriting a previous version.  Use this with caution, but be prepared for cleaner GIS directories.

On the menu bar click, Geoprocessing and Geoprocessing options-

An options box will appear.  Simply CHECK the 'Overwrite the outputs of the geoprocessing operations' and OK.  You can now geoprocess files and overwrite previous versions under the same name!  (Be sure to check out some of the other options - you might find something else really useful.)


Bug Patch for ArcGIS FLEXnet Licensing error: -15,570



    The user is intermittently unable to open ArcGIS (local installation) and connect to license server. The following error is presented: 


The License server manager (lmgrd) has not been started yet, the wrong port@host or license file is being used, or the port or hostname in the license file has been changed.

Feature: Viewer


FLEXnet Licensing error: -15,570



       The cause seems to be that the default timeout setting for the FLEXLM license manager is 2-seconds. Which is more than ample on a LAN, but less than ideal on slower VPN’s, or DSL connections.



       Solution can be found from this source to on several occasions). However, I would HIGHLY recommend that if this is indeed the patch, that we create a script for our clients to run rather than follow these steps.

  • Right click My Computer and choose properties.
  • On system property dialogue box choose advanced tab.
  • Click on the environment Variables
  • On environment variable dialogue box choose system variables field and hit the new button
  • A new system variable dialogue box with two fields appears; put “FLEXLM_TIMEOUT” in variable name and put 1000000 in variable value field
  • Click OK on all three dialogue boxes to close them


FREE GIS tools for Wildlife Habitat Connectivity, Suitability, and Occurence Modeling

Did you know there is a plethera of FREE, that's right I said FREE, ArcGIS tools and toolboxes available for wildlife habitat and corridor modeling? Conveniently, many of these tools are listed on the CorridorDesign website:

Happy Modeling!


Adding Excel .xlsx files to an ArcMap 10 document.

Don’t ask  me why but…  if you have office 2010 on your computer, you have to install the office 2007 system driver in order to see .xlsx files in ArcMap 10.

It’s a quick install.  You can find it here.

Calculating Extents in the Field Calculator

Here's a little shortcut.  You can calculate extents in the Field Calculator dialog using:

dim Output as double
dim pGeom as IGeometry

set pGeom = [shape]
Output = pGeom.Envelope.XMin

Choose advanced, paste what is above and set your field equal to Output. 

NOTE: If you want to add the values in Decimal Degrees or Web Mercator there's an app for that.  Ask Tim Williams how to install his Calculate Extent button.

Troubles with ArcGIS10 on Citrix

I am finding that I cannot connect to ArcGIS v10 on Citrix.  The application launches but it seems it's tired enough and aborts.  Are others reporting similar issues?   I've tested other applications (Word) and they open.



NHD_LLID Tools for Creating Whole Stream LLID Routes Based on NHD

The NHD LLID Tools are an ArcMap 10 Add-in programmed in ArcObjects  The purpose is to transfer the LLID whole stream route identifiers from our existing 1:100,000 whole stream route system to a whole stream route system based on the 1:24,000 NHD Hydrography, and to identify and resolve stream name conflicts between the two systems.  

The tool has three main components, organized into tabs on the ArcMap Add-in dockable window.  The first tab contains a tool to initiate an algorithm which assigns LLIDs to NHD ComID segments based on matching stream names.  The second tab provides a set of tools for assigning LLIDs to ComID segments for individual streams.  This tab also provides a tool for creating new LLID routes. The third tab provides a tool for identifying the location of stream name conflicts, as well as the nature of the conflict, how the stream was routed, why the stream was routed in this way, and what further action is required.  This portion of the application can be used without the LLID assignment functionality.

Click the following link to download the application, instructions,sample data, and sample map documents.

Unzip the LLID_RoutingTools file to C:\ .  This will create the directory C:\ NHD_LLID_Routing which includes the geodatabase NHD_LLID_Routing.mdb.  This file must be in this location for the program to function.  If you need to put the directory in another location contact

The contains the following:

- NHD LLID Routing Tools Instructions.doc. This document outlines how to use the tools to assign LLIDs to lines in the NHDFlowline layer and how to create a measured route system from these lines.

- The NHD LLID Routing Tools ArcMap 10 Add-in.

- A sample map document with no LLIDs assigned and the NHDFlowline layer unsymbolized. Start with this mxd if you would like to try out all the features of the NHD_LLID Tools. (NHDSampleUnrouted.mxd)

- A sample map document with LLIDs assigned. The State LLID route layer and the NHDFlowline layer are symbolized by LLID. The document also contains example IssuePoints highlighting discrepancies between the layers.  A completed NHD_LLID Route layer is also present. (NHDSampleRouted.mxd)

- A sample map document with the State LLID route layer and the NHDFlowline layer symbolized by Name and GNIS_Name. The document also contains example IssuePoints highlighting discrepancies between the layers.  (NHDSampleByName.mxd)

- The NHD_LLID_Routing.mdb geodatabase that supports the application.

- A sample NHD geodatabase where no LLIDs have been assigned (NHD17010304Unrouted).

- A sample NHD geodatabase where LLIDs have been assigned and a route system has been created (NHD17010304Routed).

ArcMap 10 Add-ins - Accessing the new LayerFetcher Tools

Add-ins are the new way to deploy and access ArcMap 10 custom applications and tools. There is a new and improved version of the LayerFetcher tools developed as an ArcMap 10 Add-in.   All you have to do to access the new LayerFetcher application is reference the network folder where it is located and turn on the toolbar.  To add the LayerFetcher , do the following:

1) Click Customize on the top menu bar in ArcMap 10 then click Add-In Manager.
2) Click click the Options tab then click the Add Folder button.
3) Navigate to Q:\IFWIS\AddIns and click OK. Then close Add-In Manager.
4) Click Customize then Tool Bars and check on the IDFG LayerFetcher Tools.

That’s it! No installation programs, no copying files.  And you only have to do the first three steps once.  Any other tools we place in this folder will automatically be available to you.  Just check on the tool bar. Any updates we do to existing Add-ins will be available without you doing anything.

If you find other Add-Ins that you would like to use, you can create your own AddIns folder in you folder on the Q:\ drive.  Just save the Add-in to that folder, and then follow the same steps listed above to reference it in the Add-ins Manager.

You can dock the LayerFetcher toolbar and LayerFetcher window anywhere on the main ArcMap window.

Don't like ArcGIS 10 Metadata Editor? Download the FGDC Metadata Editor add-in (just like in 9.x)

Download Page for the FGDC Metadata Editor add-in (Direct Download Link to Add-in). Thanks Michelle H. for the link update!

Option #1

  1. Download and save the attached file (fgdc.esriaddin) to your ArcGIS Desktop add-in folder (C:\Users\...\Documents\ArcGIS\AddIns\Desktop10.0)
  2. Open ArcCatalog (if open, close and re-open)
  3. In ArcCatalog go to the Customize menu and select Customize Mode
  4. On the Commands tab scroll down to the Metadata category
  5. From the Metadata Commands, drag the Show Metadata Editor command to the Metadata toolbar or someplace on the users interface to access the FGDC Editor.
Option #2 (works for if you don't have the C:\Users\...\Documents\ArcGIS\AddIns\Desktop10.0 setup)
  1. Download and save the attached file to wherever you want (I like to save this kind of stuff in the Downloads folder).
  2. Open ArcCatalog.
  3. In ArcCatalog go to the Customize menu and select Customize Mode.
  4. On the Commands tab scroll down to the Metadata category and select it.
  5. click the Add from file... button at the bottom of the window and navigate to and open the fgdc.esriaddin file you downloaded.
