Normally I run my OGR SQL syntax within OSGeo4W shell. I want to try out the GMLAS driver, but can´t find a distribution where it´s installed. I´m on windows. How do I install the GMLAS driver, working with OGR command line tool?
The GMLAS driver can not be installed. You need to install a GDAL distribution that has it built in.
The conda-forge gdal distribution includes the GMLAS driver. There may be other distributions that include it, but I only use conda.
If you don't have conda installed, I suggest miniconda.
conda create -c conda-forge -n gdal_with_gmlas gdal python and any other packages etc
conda activate gdal_with_gmlas
ogrinfo --formats|findstr GML
GML -vector- (rw+v): Geography Markup Language (GML)
GMLAS -vector- (rwv): Geography Markup Language (GML) driven by application schemas
