# 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 Type | Map of land use and cover classes. |

Weights | Categorical Map Type | Weights of Evidence coefficients. |

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

## Optional Inputs

Name | Type | Description | Default Value |
---|---|---|---|

Cell Type | Cell Type Type | Data cell type. | Unsigned 8 Bit Integer |

Null Value | Null Value Type | Null value. | Default |

## Output

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

Probabilities | Map Type | 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* 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.
