A utility is provided for mapping the spatial trend of change--a very useful abstraction tool in areas of complex change. Polynomial trend surfaces up to the 9th order can be mapped. |
|
The Biodiversity Analysis panel provides the capability of mapping five different measures
of biodiversity: alpha, gamma and beta diversity (Whittaker’s), Sorensen’s Dissimilarity
Index and an index of relative range restriction. |

The Implications tab of Land Change Modeler provides a set of utilities for species distribution modeling. In this illustration, a range polygon has been refined by establishing confidence in various portions of the original polygons based on a modeling from environmental variables. This confidence mapping then weights the mean and variance-covariance matrix that underlies the calculation of Mahalanobis Typicalities for modeling from presence data.

The Change Analysis panel provides a set of tools for understanding the nature and extent of landcover change, including graphs of gains and losses, net changes and contributions experienced by any category. A simple one-click interface provides the ability to generate rapid maps of change, persistence, specific transitions and exchanges between categories.
|
|
Tools are available for the detection of change including gap analysis, most often
characterized by gaps in protected habitat for a specific species. |
|
Running the prediction process will yield hard and soft prediction maps. This soft prediction maps vulnerability to change for a selected set of transitions and provides a comprehensive assessment of change potential.
