terrain: Utility Functions for Terrain Derivatives Calculations

The goal of terrain is to have a useful toolbox to calculate terrain derivatives using RSAGA. The package is for my personal use, with selected RSAGA terrain derivatives, and not meant to be comprehensive. Several defaults are hard-coded.

For the package to work, there should be a local executable of the SAGA software available.

It is not meant for CRAN, and hence most of the functions will write to disk.

Installation

You can install the package from GitHub with:

remotes::install_github("loreabad6/terrain")

RSAGA selected terrain derivatives

A list of the selected RSAGA terrain derivatives follows below, refer to function code documentation for a short description of each derivative.
