A straightforward helper tool for linking GI/RS functionality to R. The goal of the package
is to correctly initialize both the existing wrapper packages rgrass
and RSAGA
and
to smoothly enable the necessary system variables and path parameters for a direct access of the binaries
via direct system calls on all operating systems. In particular, rgrass
and RSAGA
can cause severe
problems during initialization of parallel installations of GRASS GIS
or SAGA GIS
under the
Windows operating system(s). link2GI
tries to set the correct system settings and returns if system
calls are required the necessary paths and command strings.
Furthermore the package provides a linkage to the Orfeo Toolbox (OTB) software.
Due to the difficulties linking the correct GDAL binaries a new system wide search for GDAL binaries is implemented.
Finally there are some usefull functions for creating project folder structures and project environments. To deal with the not always consistent API-calls of OTB a list based command parser and generator is provided.
Functions for linking GI/RS functionality to R
To utilize the power of the open source GI tools from within R
you need to install them first.
The link2GI package just tries to generate correct environment settings as system and path variables
for the most of the known issues.
The installation of the QGIS, GRASS GIS 7.x
and SAGA-GIS
GIS software is described in the vignettes.link2GI
is tested under Windows 7/10 as well as on the Ubuntu/Debian/Arch Linux distributions.
The OSX operation system should run but is not tested (Any help is highly appreciated).
