# Calc W. Of E. Probability Map (Calc Weights of Evidence Probability Map)

## Description

This container calculates a probability map applying the Weights of Evidence method.

## Inputs

Name | Type | Description |
---|---|---|

Landscape | Categorical Map | Map of land use and cover classes |

Weights | Categorical Map | Weights of Evidence coefficients |

Transitions | Transition Set | List of transitions for which spatial probability maps will be calculated. |

Transitions | Transition Set | List of transitions for which spatial probability maps will be calculated. |

## Optional Inputs

## Output

Name | Type | Description |
---|---|---|

Probabilities | Map | Map of probabilities. |

## Group

## Notes

The spatial transition probability maps depict the probability of a cell at position *(x,y)* to change from state <i>i</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.
