Notes

The spatial transition probability maps depict the probability of a cell at position (x,y) to change from state i to state j. The spatial transition probabilities are calculated for each cell on the landscape raster map and for each specified transition. Dinamica employs the Weights of Evidence method, which uses a general polytomous logistic equation (see equation) to select the most favorable areas for each type of transition. The calculations are made using spatial variables stored in the GIS.
