saga_cmd

One of the simplest yet most tricky ways of doing batch processing is by using Bash scripts. Bash is a type of Shell Script, which means it runs directly on a user interface that accesses the services of an operating system.

Last week, we talked a little about using SAGA on Command Line. Today, I am discussing solutions to the problem “Error: Catchment Area” on SAGA GIS. Or “Error: your input raster”, or “Input layers do not have the same grid extent”.

SAGA also has its own Graphical User Interface (GUI). And it also has its own Command Line version. One may ask, why would someone deliberately choose to use a Command Line version in detriment of a GUI? Well, a GUI uses its own share of memory, CPU, sometimes GPU, to run.
