SAGA.grid_analysis.21: Diversity of Categories

Grid based analysis of diversity. It is assumed that the input grid provides a classification (i.e. not a contiuous field). For each cell it counts the number of different categories (classes) as well as the connectivity within the chosen search window.

Inputs

Categories

href
Please set a value for CATEGORIES.

Search Mode

string
