Focus Paper: Species Distribution Modeling in IDRISI's Land Change Modeler
Species distribution modeling has become an increasingly important technique in conservation planning. A model generates a representation of the relationship between the presence of a species and a set of environmental factors. It then extrapolates this information to create maps of habitat suitability or species' geographic ranges. This paper provides a general overview of this technique within IDRISI and features a case study of modeling the Brown-Throated Sloth.

Focus Paper: Modeling REDD Baselines using IDRISI's Land Change Modeler
Reducing Emissions from Deforestation and Forest Degradation (REDD) is an incentive-driven climate change mitigation strategy for the protection and maintenance of forests, the conservation of which yields great potential for reducing greenhouse gas emissions. This paper provides an overview of the modeling of a REDD baseline--determining the historical deforestation rates and patterns as well as identifying the unique causes and agents of deforestation--utilizing a case study of an actual REDD project developed in Madagascar.

Focus Paper: Exploring Image Time Series with Earth Trends Modeler
Environmental 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.

Focus Paper: Classification Tree Analysis
Classification 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.

Focus Paper: Segmentation and Segment-based Classification
Unlike 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.
