LCM provides the capability for both hard and soft projection of change into the future. Both modes accommodate the recalculation of dynamic variables and dynamic road growth. Hard prediction models a single realization while soft prediction maps the spatial pattern and potential for change.


IDRISI supports a variety of image restoration and transformation tools. In this image, the module ATMOSC is used for atmospheric correction.


IDRISI allows on-screen digitizing of training sites and the development and analysis of signatures including signature comparison, measures of separability, and scattergrams.


IDRISI has tools for the validation of classified maps to reality including cross tabulation and error matrix analysis.


IDRISI automates Change Vector Analysis. Given two bands from two different dates, images of change magnitude and change direction are produced. The magnitude image may be thresholded to isolate areas of change versus areas of normal variation while the change direction image may be used to identify the types of change that have occurred (e.g., harvest vs. growth).


Image differencing is a common technique for change analysis. IDRISI includes output options for a simple difference image, a percentage difference image, a standardized (z-score) difference image, or a standardized class image (6 categories of z-scores).


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.
