initRGIS: Initializes RSAGA, rgrass7 and gdalUtil
In gisma/robubu: the rolling burning bus - whatever, it runs fine for now

Description Usage Arguments Details Value Author(s) Examples

Function that initializes environment, pathes, SAGA, GRASS7 and GDAL support via gdalUtils. *NOTE* you probably have to customize some settings according to your personal installation folders.

1	initRGIS(fname.control,)

`root.dir`	project directory
`working.dir`	runtime directory
`fndem`	name of a (DEM) GDAL format raster file
`rasterParam`	a rasterobject link

The concept is very straightforward but for an all days usage pretty helpful. You need to provide a GDAL conform raster file, a raster object or you may download SRTM data with getGeoData. This settings will be used to initialize a temporary but static rgrass7 environment. Additionally RSAGA and gdalUtils are initialized and checked. During the rsession you will have full access to GRASS7 and SAGA via the wrapper packages. .

initRGIS initializes the usage of GRASS7 RSAGA 2.12+ and gdalUtil
it returns the RSAGA env, the GRASS env and the gdalUtils status

#### Examples how to use RSAGA and GRASS bindings from R

# full call using getGeodata
envGIS<- initRGIS <- function(root.dir=tempdir(),working.dir='cost',fndem=getGeoData("SRTM",xtent=c(49,49,11,11)))

# initialisation with an existing raster object
envGIS<- initRGIS("~/proj/tester",'cost',fndem=NULL,rasterParam = outraster)

# init with an local GDAL file
envGIS<- initRGIS("~/proj/tester",'cost',"~/proj/runbeetle/srtm_43_01.tif")
