QGIS Algorithm provided by SAGA Next Gen Topographic correction (sagang:topographiccorrection). —————- Arguments —————- DEM: Elevation Argument type: raster Acceptable values: - Path to a raster layer ORIGINAL: Original Image Argument type: raster Acceptable values: - Path to a raster layer CORRECTED: Corrected Image Argument type: rasterDestination Acceptable values: - Path for new raster layer AZI: Azimuth Default value: 180 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 HGT: Height Default value: 45 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 METHOD: Method Default value: 4 Argument type: enum Available values: - 0: (0) Cosine Correction (Teillet et al. 1982) - 1: (1) Cosine Correction (Civco 1989) - 2: (2) Minnaert Correction - 3: (3) Minnaert Correction with Slope (Riano et al. 2003) - 4: (4) Minnaert Correction with Slope (Law & Nichol 2004) - 5: (5) C Correction - 6: (6) Normalization (after Civco, modified by Law & Nichol) Acceptable values: - Number of selected option, e.g. '1' - Comma separated list of options, e.g. '1,3' MINNAERT: Minnaert Correction Default value: 0.5 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 MAXCELLS: Maximum Cells (C Correction Analysis) Default value: 1000 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 MAXVALUE: Value Range Default value: 0 Argument type: enum Available values: - 0: (0) 1 byte (0-255) - 1: (1) 2 byte (0-65535) Acceptable values: - Number of selected option, e.g. '1' - Comma separated list of options, e.g. '1,3'
