Analysis Tools

Overview

The Geospatial Laboratory for Soil Informatics (GLSI) provides a suite of four different tools designed to enhance the analysis of soil, geomorphometry, and spatial relationships. Explore our ArcGIS toolboxes and Excel macros to improve data accuracy, uncertainty quantification, and geospatial modeling in soil and environmental sciences.

  • Error Propagation Toolbox

    This ArcGIS toolbox provides a method for quantifying uncertainty in map algebra. It applies standard error propagation equations to assess the reliability of calculations, particularly in modeling and raster-based computations. This tool is essential for spatial layer mashups, where input variables from different grids contribute to calculated outcomes.
