rsaga.sgrd.to.esri Convert SAGA grids to ESRI ASCII/binary grids
Description
rsaga.sgrd.to.esri converts grid files from SAGA’s (version 2) grid format (.sgrd) to ESRI’s
ASCII (.asc) and binary (.flt) format.
Usage
rsaga.sgrd.to.esri(in.sgrds, out.grids, out.path, format = "ascii",
georef = "corner", prec = 5, ...)
Arguments
in.sgrds
character vector of SAGA grid files (.sgrd) to be converted; files are expected
to be found in folder rsaga.env()$workspace, or, if an optional env
argument is provided, in env$workspace
out.grids
character vector of ESRI ASCII/float output file names; defaults to in.sgrds
with the file extension being replaced by .asc or .flt, depending on format.
Files will be placed in folder out.path, existing files will be overwritten
out.path
folder for out.grids
format
output file format, either "ascii" (default; equivalent: format=1) for ASCII
grids or "binary" (equivalent: 0) for binary ESRI grids (.flt).
georef
character: "corner" (equivalent numeric code: 0) or "center" (default;
equivalent: 1). Determines whether the georeference will be related to the center
or corner of its extreme lower left grid cell.
prec
number of digits when writing floating point values to ASCII grid files; either
a single number (to be replicated if necessary), or a numeric vector of length
length(in.grids)
...
optional arguments to be passed to rsaga.geoprocessor, including the
env RSAGA geoprocessing environment
Value
The type of object returned depends on the intern argument passed to the rsaga.geoprocessor.
For intern=FALSE it is a numerical error code (0: success), or otherwise (default) a character
vector with the module’s console output.
Note
This function uses module 0 from the SAGA library io_grid.
