Overview

Clark Labs offers products to facilitate the analysis of geospatial information.

TerrSet Geospatial Monitoring and Modeling Software

TerrSet is an integrated geospatial software system for monitoring and modeling the earth system. The TerrSet System incorporates the IDRISI GIS Analysis and IDRISI Image Processing tools along with a constellation of vertical applications.

Land Change Modeler for ArcGIS

Land Change Modeler for ArcGIS is a revolutionary land cover change analysis and prediction software with tools to analyze, measure and project the impacts of such change on habitat and biodiversity. Land Change Modeler exists in TerrSet and also as an extension to ArcGIS 10.2.

Both products operate on Microsoft Windows operating systems and come with extensive tutorials and data to facilitate your analysis.

 

 
TerrSet Earth Trends Modeler for Temporal Data Mining from Earth Observation Imagery

The Earth Trends Modeler (ETM) is specially designed for the analysis of earth observation image time series. In this illustration, a series of 348 global images of monthly NDVI vegetation index data were analyzed for the presence of trends in seasonality. Pixels colored gray (which are almost absent) indicate a stable seasonality. All other colors represent trends. ETM provides an interactive legend (lower left) to interpret the trend for any area (the area in eastern Alabama and western Georgia in this case). The green curve represents the beginning of the series (1982) while the red one represents the end (2010). The X axis is time and the Y axis is NDVI. As can be seen, NDVI has generally increased with a growing bimodality. Spring is coming a bit earlier (11 days) and the autumn is extending longer (almost 30 days).
