rsaga.sgrd.to.esri {RSAGA} | R Documentation |
rsaga.sgrd.to.esri
converts grid files from
SAGA's (version 2) grid format (.sgrd) to ESRI's ASCII (.asc)
and binary (.flt) format.
rsaga.sgrd.to.esri(in.sgrds, out.grids, out.path, format = "ascii", georef = "corner", prec = 5, ...)
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 |
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.
This function uses module 0 from the SAGA library io_grid
.
