TEUI toolkit

The TEUI toolkit works in a similar manner to Zonal Statistics as Table within ArcGIS, with the added benefit of interactive graphics to aid in the assessment. TEUI is an ArcGIS Add-in and may be installed without Administrator privilege. Additional information and downloads are available here:


One advantage of TEUI is the ability to output tabular data at both the map unit and polygon level with one operation. SECTIONS 2 - 5 of the TEUI User Guide are excerpted below.

SECTION 2. Creating and opening an existing project

The Toolkit requires the user to specify a folder location to store the database that contains the statistics and the file location of the data used to create them. This database can be an existing project folder location, but it is recommended that a new folder be created to reduce the number of extraneous files in a folder with other data.

Create a New Toolkit Project

  1. On the TEUI Toolbar, select the Folder icon. R GUI image

  2. A dialog window will appear.

  3. Select Browse…

  4. In the Browse for Folder dialog, navigate to a location of your choice and select “Make New Folder”

  5. Type in an appropriate name for your project

  6. Click OK

Open an Existing Toolkit Project

  1. On the TEUI Toolbar, select the Folder icon R GUI image

  2. A dialog window will appear.

If the project was recent, click on the project in the Recent dialog box and click Open. If it is older and does not appear in the dialog box, select Browse and navigate to the project folder location. Select the project and click OK.

SECTION 3. Manage geospatial data and calculate statistics

Managing project data with version 5.0 is very simple. The user simply points the program to the file location of the data on your computer that is to be used in the analysis.

Note: If you move the geospatial data used in an existing Toolkit project, you will need to re-link the Toolkit to the data when opening that project.

Add Analysis Features to a Toolkit Project

  1. On the TEUI Toolbar, select the Data Manager icon. R GUI image
  2. The Data Manager dialog window will appear.

Analysis Features: are zones within which you would like to generate statistics. These features can be feature classes such polygons or points (line features will be available soon) as a shapefile (.shp), as a feature class within a file geodatabase, or within a feature dataset within a file geodatabase. Analysis features can also be in the form of a discrete raster. The value field will be used as the identifier.

Rasters: are the raster data that are to be used to generate the descriptive statistics. An example would be a digital elevation model (DEM), percent slope, aspect, or land use for a discrete raster.

  1. In the Analysis Features area, click on the Add Layer button.

  1. A data navigation window will appear. Navigate to the analysis layer you wish to use and select Add. You can add as many data layers as you wish to analyze.

Note: All data layers to be analyzed (analysis features and raster data) must have the same geographic coordinate system and projection as each other. You will receive a warning if they are different.

Remove Analysis Features from a Toolkit Project

  1. To remove an analysis layer from the Data Manager, click on the layer you wish to remove in the grey layer list, and click Remove. Click OK when prompted that this is correct.

Add Analysis Features to the ArcMap Table of Contents

  1. To add the selected layer to the ArcMap table of contents, select the layer you wish to add by clicking on it in the grey layer list, and click the Add to Table of Contents button.

Choose a Map Unit

In some instances, such as TEUI mapping or Soil Survey, you may wish to identify individual polygon features as belonging to a specific map unit. This is simply a repeating identifying symbol or value which will be used to aggregate the statistics of the polygons belonging to that group. You do not need to select a map unit column in order to run the Toolkit. The symbol must be present as an attribute column in either the feature class layer or as an attribute in the VAT table of a discrete raster.

  1. Select the Analysis Feature layer that you wish to add a Map Unit symbol for.

  2. Select the appropriate map unit column attribute name for your map unit symbol in the drop down menu
