QGIS Algorithm provided by SAGA Next Gen Convergence index (search radius) (sagang:convergenceindexsearchradius). —————- Arguments —————- ELEVATION: Elevation Argument type: raster Acceptable values: - Path to a raster layer CONVERGENCE: Convergence Index Argument type: rasterDestination Acceptable values: - Path for new raster layer SLOPE: Gradient Default value: false Argument type: boolean Acceptable values: - 1 for true/yes - 0 for false/no - field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field - expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression DIFFERENCE: Difference Default value: 0 Argument type: enum Available values: - 0: (0) direction to the center cell - 1: (1) center cell's aspect direction Acceptable values: - Number of selected option, e.g. '1' - Comma separated list of options, e.g. '1,3' RADIUS: Radius (Cells) Default value: 10 Argument type: number Acceptable values: - A numeric value - field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field - expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression DW_WEIGHTING: Weighting Function Default value: 0 Argument type: enum Available values: - 0: (0) no distance weighting - 1: (1) inverse distance to a power - 2: (2) exponential - 3: (3) gaussian Acceptable values: - Number of selected option, e.g. '1' - Comma separated list of options, e.g. '1,3' DW_IDW_POWER: Power Default value: 2 Argument type: number Acceptable values: - A numeric value - field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field - expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression DW_BANDWIDTH: Bandwidth Default value: 1 Argument type: number Acceptable values: - A numeric value - field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field - expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression
