TIN Interpolation tin Generate a triangulated irregular network TIN model from either isoline vertices or vector point input data using either a constrained or non-constrained Delaunay triangulation. Vector files can also be transformed. Tabulate errors of omission and commission, marginal and total error, and selected confidence intervals. Mean, gaussian, median, adaptive box, mode, Laplacian edge-enhancement, high-pass, Sobel edge detector and user-defined filters are accommodated.

Errors & Problems

What’s New in Release 2 An orientation to the new features of the system. Dynamic and batch modeling is also supported. For text symbol files, font, size, form and color may be changed. What’s New In Release 2. Merge higher-resolution panchromatic images with lower-resolution multi-spectral composites. – /nisl/GIS/IDRISI/Idrisi32 Tutorial/MCE/

For polygon symbol files, outline color, fill type and color may be modified. View byte level content of binary files. Both include simple statistics. Employs the Analytical Hierarchy Process AHP with information on consensus and with procedures for resolving lack of consensus. Transformation pca Perform tuhorial or unstandardized Principal Components Analysis. The iterative process makes use of a full maximum likelihood procedure.


Up to input images can be analyzed as a group with the production of an equal number of resulting components. This module idridi32 particularly important in the development of Monte Carlo simulations for error propagation. Per-category Kappa Index of Agreement figures are also provided. Idrisi32 is fully COM compliant.

An ignorance image is also produced expressing the incompleteness of knowledge as a measure of the degree to which hypotheses i. Local neighborhood and sample selection supported by a variety of methods. With raster images, tuutorial resampling is undertaken using either a nearest-neighbor or bilinear interpolation.

With the introduction of Idrisi32 Release 2, Clark Labs reaffirm their commitment to providing affordable access to the frontiers of spatial analysis and to advancing their role as an educational and research institution dedicated to geographic inquiry and understanding.

Numeric output includes proportional and cumulative frequencies. Prior probabilities may vary continuously over space. Modeling geometric and zonal anisotropy supported.

The transition matrix records the probability that each land cover category will change to every other category while the transition areas matrix records the number of pixels that are expected to change from each land cover type to each other land cover type over the specified number of time units.


An image that expresses the degree of classification uncertainty about the class membership of the pixels is also produced. Choose whether diagonal neighbors are considered contiguous. For point symbol files, symbol shape, color and size may be modified. A user-defined function capability is also available.

The procedure is suitable for use with massive tytorial sets. Non-rectangular regions can be analyzed by defining a binary mask. Topographic Variables slope Produce a slope idrisu32 image from a surface model. Kriging spatial dependence modeler Modeling tools for spatial variability or spatial continuity using semivariogram, robust semivariogram, isrisi32 and correlogram, cross variogram, crosscovariogram, and cross correlogram methods.

CartaLinx is not included with the Idrisi32 package, but if it is installed, it can be launched from Idrisi Plot a temporal profile of up to 15 sites across a time series group or over a hyperspectral series. Set view direction, angle above the horizon and vertical exaggeration factor.

Using the logic of Dempster-Shafer theory, a whole hierarchy of classes can be recognized, made up of the indistinguishable combinations of these classes.

Output can be an image, table or values file in a range of measurement units.
