R: Convert SAGA grids to ESRI ASCII/binary grids

rsaga.sgrd.to.esri {RSAGA}

R Documentation

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.
