gdalUtils (version 0.2.0)

gdal_chooseInstallation: gdal_chooseInstallation

Description

Choose a GDAL installation based on certain requirements.

Usage

gdal_chooseInstallation(hasDrivers)

Arguments

hasDrivers

Character. Which drivers must be available?

Value

• Numeric id of the most recent installation that matches the requirements.

Details

By default, the GDAL commands will use the installation found at getOption("gdalUtils_gdalPath")[[1]], which is the most recent version found on the system. If the user has more than one GDAL installed (more common on Windows and Mac systems than *nix systems), gdal_chooseInstallation can be used to choose an installation (perhaps not the most recent one) that has certain functionality, e.g. supports HDF4 formatted files.
