In vaster: Tools for Raster Grid Logic

Target size and extent for GDAL command line

Description

Format grid properties for GDAL command line options (-ts for target size, -te for target extent).

Usage

ts_te(dimension, extent)

gdal_te(extent)

gdal_ts(dimension)

Arguments

dimension	integer vector of ncol, nrow (target size)
extent	numeric vector of xmin, xmax, ymin, ymax (target extent)

Details

These functions generate the string arguments used by GDAL utilities like gdalwarp and gdal_translate. The gdal_ts() function is named after the GDAL -ts flag and gdal_te() after the GDAL -te flag.

Value

A character string formatted for GDAL command line:

• ts_te(): combined -ts and -te arguments

• gdal_ts(): ⁠-ts ncol nrow⁠ string

• gdal_te(): ⁠-te xmin ymin xmax ymax⁠ string (note: reordered for GDAL)

Examples

ts_te(c(10, 100), 1:4)

gdal_ts(c(10, 100))

gdal_te(1:4)
