Frequently Asked Questions

  • Will ET GeoWizards work with ArcGIS 10.2

Yes. ET GeoWizards 11.0, ET GeoTools 11.0 and ET Surface 5.0 (to be released in September 2013) are available in four sub- versions with the same functionality:

  • for ArcGIS 9.3 (supports 9.3 and 9.3.1)
  • for ArcGIS 10.0
  • for ArcGIS 10.1
  • for ArcGIS 10.2

ArcGIS 9.2 users can use ET GeoWizards 10.2, ET GeoTools 10.2 and ET Surface 4.1

ArcGIS 9.0 and 9.1 users can use ET GeoWizards 9.9, ET GeoTools 9.5 and ET Surface 2.0

ArcGIS 8.x users can use ET GeoWizards 9.7 and ET GeoTools 9.3

  • When I try to install ET GeoWizards 10.0 on ArcGIS 9.3.1 I get the following error: "Unable to get installer types in C:\Program Files\..\ETGeoWizards.dll assembly -> Unable to load one or more of the requested types. Retrieve the Loader Exceptions properly for more information."

Most probably the .NET support for ArcGIS is not installed or installed incorrectly. To correct this:

  • Start the ArcGIS installation (from a DVD or a backup location)
  • Select Modify and click Next
  • Click on .NET Support and select "Will be installed on local hard drive"
  • Finish the installation
  • Run the setup of ET GeoWizards, ET GeoTools or ET Surface again
  • What ESRI formats can be used as outputs?

It depends on your version of ArcGIS. 

  • ArcGIS 9.2 and above - Shapefiles, standalone Personal and File Geodatabase feature classes. 
  • Pre ArcGIS 9.2 ( versions 8.1 to 9.1) - Shapefiles and standalone Personal Geodatabase feature classes.
  • Why I cannot place the output in a feature dataset?
The feature classes of a feature dataset might participate in Topologies, Geometric networks, etc.  The results of 99% of the functions of ET GeoWizards are written into a new  dataset (feature class or shapefile). In many cases the result is not final - it goes trough several procedures before the final dataset is derived. To avoid placing feature classes into feature datasets that have been structured to do something, we on purpose have disabled ET GeoWizards to output in feature datasets. It is very easy to copy the result to a feature dataset after the user is sure that the desired result is obtained. One can always make a model that will use the ET GeoWizards tools and just add at  the end the standard "Feature Class To Feature Class" tool to direct the output to a feature dataset.
  • If I purchase ET GeoWizards for ArcGIS 9.0, do I need to purchase the version for ArcGIS 9.2 when I upgrade?

No. A license of ET GeoWizards is valid for all the sub-versions of the software. When you switch to ArcGIS 9.2, you just need to uninstall your current ET GeoWizards version, download and install the version for ArcGIS 9.2.

  • It would be nice to have a "Smooth polygon" function that works something like the smooth polyline.

We published a white paper addressing this problem.  Read it here

NEW: ET GeoWizards 9.6 and above have a function that will perform polygon smoothing directly.

  • Are there any limitations of the registered version of ET GeoWizards?

    In general there are no limitations. The performance is very much dependent on the RAM available. The recommended RAM size is at least 2 Gb . If there are some limitations imposed by ArcObjects objects (no such limitations currently known) they will apply to the functions of ET GeoWizards that are using them.

  • Has there been any considerations on the ability to add these tools into model builder.

Yes, the ToolBox implementation of ET GeoWizards was introduced in version 9.2.  ET GeoWizards 9.7 has 94 tools available for use in ArcToolbox environment -  Model Builder, Command Line, Python, Java or VB scripting

  • Can I use ET GeoWizards with an ArcView license?

Yes.  All functions of ET GeoWizards, ET GeoTools and ET Surface can be used with any type of license (ArcView, ArcEditor, ArcInfo) 

  • What is the difference between the “Fuzzy” tolerance used in ET GeoWizards and the “Cluster” tolerance used in the Integrate function of ArcEditor?

Practically there is no difference. The Integrate function of ArcEditor and ArcInfo does not correct the topology of a data set, it just snaps the vertices that are within the Cluster tolerance together. If for example there are two polylines that are closer to each other than the cluster tolerance, Integrate will only make them coincident. The clean functions of ET GeoWizards will use the Fuzzy tolerance to snap the vertices together, create intersections and clean the duplicate features. The term fuzzy tolerance is used in the topology functions of Arc/Info and therefore is more suitable for ET GeoWizards.
