Focus PapersFocus Paper: Exploring Image Time Series with Earth Trends ModelerEnvironmental image series provide a critically important resource for understanding both the dynamics and evolution of environmental phenomena. Earth Trends Modeler, a vertical application within the IDRISI software system, provides a wealth of tools for the analysis of trends and relationships evident in time series images. This paper explores several of the many data mining techniques, using for our example, monthly sea surface temperature data from 1982 to 2007. Download the Exploring Image Time Series with Earth Trends Modeler Focus Paper Focus Paper: Land Change Modeler for Ecological SustainabilityLand Change Modeler is a software solution that provides tools for the assessment and prediction of land change, as well as the impacts for habitat and biodiversity. This Focus Paper describes the modeling logic of these tools and presents the typical workflow. Download the Land Change Modeler Focus Paper. Focus Paper: Classification Tree AnalysisClassification Tree Analysis is a type of machine learning algorithm used for classifying remotely sensed and ancillary data in support of land cover mapping and analysis. This Focus Paper offers an explanation of this procedure and its implementation within IDRISI. Download the Classification Tree Analysis Focus Paper. Focus Paper: Segmentation and Segment-based ClassificationUnlike traditional pixel-based classification methods, segment-based classification is an approach that classifies a remotely-sensed image based on image segments. Segmentation is the process of defining homogeneous pixels into these spectrally similar segments. This Focus Paper explores how this functionality is incorporated within IDRISI and outlines the workflow. Download the Segmentation and Segment-Based Classification Focus Paper.
