rsaga.sgrd.to.esri: Convert SAGA grids to ESRI ASCII/binary grids

Description Usage Arguments Value Note Author(s) See Also

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

1
2
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.
