QGIS Algorithm provided by SAGA Next Gen Gradient vectors from surface (sagang:gradientvectorsfromsurface). —————- Arguments —————- SURFACE: Surface Argument type: raster Acceptable values: - Path to a raster layer VECTORS: Gradient Vectors Argument type: vectorDestination Acceptable values: - Path for new vector layer STEP: Step 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 AGGR: Aggregation Default value: 1 Argument type: enum Available values: - 0: (0) nearest neighbour - 1: (1) mean value Acceptable values: - Number of selected option, e.g. '1' - Comma separated list of options, e.g. '1,3' STYLE: Style Default value: 2 Argument type: enum Available values: - 0: (0) simple line - 1: (1) arrow - 2: (2) arrow (centered to cell) Acceptable values: - Number of selected option, e.g. '1' - Comma separated list of options, e.g. '1,3'
