IDRISI Taiga Product FeaturesIDRISI Taiga is an integrated GIS and Image Processing software solution for the desktop. Researchers and professionals work primarily with raster data in areas such as climate change modeling, land change planning, natural resource & environmental management, and ecosystem dynamics. The Taiga Edition, released in January 2009, is the 16th major release of the IDRISI software since 1987. GIS AnalysisThe most extensive tool set for raster GIS analysis including standard and advanced spatial statistics and modeling, interpolation and hydrological modeling routines, and comprehensive distance and context operators. Decision SupportCutting-edge tools for multi-criteria and multi-objective decision making and land suitability analysis and evaluation. Earth Trends ModelingEarth Trends Modeler is a modeling application integrated within IDRISI to analyze trends and anomalies in image time series with particular relevance for climate change and ecosystem dynamics. Land Change ModelingLand Change Modeler is a modeling application integrated within IDRISI that includes tools to quickly assess land change, predict future scenarios and assess the impacts of these predictions on biodiversity. Land Change Modeler is widely used for REDD projects. Image Processing
Other Features
Earth Trends Modeler provides an integrated environment for the analysis of time series data. Here an analysis of trends in sea surface temperature from 1982 to 2006 shows a strong increasing trend of temperature in the Atlantic and its relation to the Atlantic Multidecadal Oscillation (AMO). The triangular wavelet analysis diagram shows the nature and scale of these trends in the Labrador Sea. The animated globe shows variations in ocean height which are closely related with temperature variations.
Land Change Modeler provides a set of tools for the rapid assessment and mapping of change, allowing for one-click evaluations of land cover gains and losses, net change, and persistence, both in map and graphical form.
In Earth Trends Modeler, an analysis of trends in MODIS land surface temperature in degrees Celsius from 2000-2006. The map shows warming zones in North America, Eurasia, and Australia. Large cooling zones are depicted in Southern Europe and throughout Asia.
IDRISI allows on-screen digitizing of training sites and the development and analysis of signatures including signature comparison, measures of separability, and scattergrams.
Classification Tree Analysis is a type of machine learning classifier. Procedures are included for training and pruning a classification tree. This module produces both hard and soft classified maps. There is one soft map for each class associated with the degree of membership for that class at a particular leaf in the tree structure.
IDRISI includes land cover validation tools which allow you to validate your land cover change models. In this example, a model was developed to predict land cover change based on historical patterns. Projected land cover was compared to actual land cover to validate the model in terms of both quantity and location of change.
The IDRISI Macro Modeler provides a graphic environment for the construction of models. Facilities are included for batch processing of multiple images through the same model and for iterative processing with the output of one iteration becoming an input to the next.
