SAGA GIS Wiki

SAGA ships with modules that can be executed in every environment (GUI, CMD, Python) and ones that are interactive and thus can be only executed in SAGA GUI. The latter require user interaction like drawing a profile line in a map view.

In general, each module is structured in an input data section, an output data section and an options sections used to specify the necessary parameters to run the module with. The input and output data is further subdivided in datasets required and datasets that are optional.

To perform calculations on several raster datasets at once, these must (in most cases) share the same grid system. I.e. these grids must have the same origin, cell-size and extent. In case you like to process raster datasets not fulfilling this requirement, you will first have to use one of the available modules to merge the datasets into one grid system (see Grid System Matching <link>). This may require merging, patching, resampling or reprojection of the datasets. The next sections give an overview on the general concepts you need to know to execute a module in the corresponding environment.
