The Terrestrial Ecological Unit Inventory Geospatial Toolkit (TEUI Toolkit) is an ArcGIS AddIn that assists users in mapping and analyzing landscapes using geospatial data. The Toolkit was designed to accelerate the TEUI mapping process but can also be used for a variety of other natural resource mapping efforts.
The TEUI Toolkit 5 has been completely redesigned and engineered to be faster and more robust than ever.
The Toolkit utilizes both continuous and discrete raster data (e.g., slope, aspect, elevation), polygon data (e.g., map units), and point data (e.g., soil pedon or vegetation plots) to calculate zonal statistics and display the results in both a tabular and graphical format.
The TEUI Toolkit was developed and is maintained by the USFS Remote Sensing Applications Center in Salt Lake City, UT.
The TEUI Toolkit can use any continuous or discrete raster data provided that it is numeric. Some examples include: slope, aspect, elevation, temperature, precipitation, and curvature. To use thematic data like geology, you will have to convert each symbol to a number. For analysis zones, any feature class type (i.e. polygon, point, line) or discrete raster data layer can be used.
Remember, if you are working on USFS land, the USFS Remote Sensing Applications Center can provide you geospatial data for your project area. Send an e-mail to
The TEUI-Geospatial Toolkit can be used by anyone who wants to analyze and perform zonal statistics. Additional features for accelerating mapping such as sample design and data mining are currently under development.
Originally developed for the mapping and analysis of Terrestrial Ecological Units, the TEUI-Geospatial Toolkit can also be used to analyze or map any natural phenomena. Non-TEUI projects have included range analysis, watershed analysis, TES analysis, vegetation mapping, wildlife habitat, scenic areas, and soil mapping.
