Clark Labs recently released its newest version of its geospatial and image processing software IDRISI called IDRISI Selva. IDRISI Selva is the 17th version of IDRISI which offers brand new features and significant updates to its predecessor IDRISI Taiga. IDRISI offers a suite of tools for basic and advanced spatial analysis, surface and statistical analysis, change and time series analysis, modeling, and decision support and uncertainty. IDRISI also offers a diversity of image processing tools including a variety of hard and soft classifiers, machine learning algorithms, and image segmentation tools. This latest version adds new tools to the Earth Trends Modeler application for the analysis of patterns and trends in earth observation image time series and new REDD-specific tools to the Land Change Modeler application for the modeling, prediction and impact assessment of land cover change. New analytical techniques and greater import/export support have been added, display and map composition elements have been enhanced and expanded and existing modules have been optimized.
More specifically some changes include:
- Land Change Modeler has been enhanced and new modeling tools have been added such as SimWeight and tools to support modeling and accounting for REDD (Reducing Emissions from Deforestation and Forest Degradation) projects. An integrated interface to the Maxent software for species distribution modeling has also been added.
- Earth Trends Modeler has been enhanced with new tools for the analysis of coupled systems such as the oceans and atmosphere. These include Extended PCA/EOF, Multi-channel Singular Spectrum Analysis, Extended EOT, Multichannel EOT and Canonical Correlation Analysis.
- New tools have been added such as Radial Basis Function (RBF) neural network classifier, Chain Clustering, and Durbin-Watson modules.
- Existing tools such as the distance based modules have been optimized for greater speed and the PCA module has been expanded. In addition, MODIS and Google KML file import and export support has been enhanced.
- New support for image pyramids and large images up to 2 billion rows by 2 billion columns have been added.
