Import Grid Files to SAGA grid format using GDAL

Description

These functions provide simple interfaces for reading and writing grids from/to ASCII grids and Rd files. Grids are stored in matrices, their headers in lists.

Usage

rsaga.import.gdal(in.grid, out.grid, env = rsaga.env(), ...)

Arguments

`in.grid`	file name of a grid in a format supported by GDAL
`out.grid`	output SAGA grid file name; defaults to `in.grid` with the file extension being removed; file extension should not be specified, it defaults to `.sgrd`
`env`	RSAGA geoprocessing environment created by `rsaga.env()`
`...`	additional arguments to be passed to `rsaga.geoprocessor`

Details

The GDAL Raster Import module of SAGA imports grid data from various file formats using the Geospatial Data Abstraction Library (GDAL) by Frank Warmerdam. GDAL Versions are specific to SAGA versions:

SAGA 2.1.2 - 2.2.0: GDAL v.1.11.0
SAGA 2.2.1 - 2.2.3: GDAL v.2.1.0 dev
...
SAGA 8.4.1: GDAL v3.3.0 More information is available at https://gdal.org/.

If in.grid has more than one band (e.g. RGB GEOTIFF), then output grids with file names of the form in.grid{\_}01.sgrd, in.grid{\_}02.sgrd etc. are written, one for each band.

Numerous raster formats are currently supported. For SAGA 8.4.1 see e.g. https://saga-gis.sourceforge.io/saga_tool_doc/8.4.1/io_gdal_0.html
