ALKIS NAS converter

Tiny commandline tool for conversion of ALKIS NAS konvois to (Q)GIS compatible data formats.

shell script for unix, dependent on gzip and ogr2ogr
batch script for windows, dependent on QGIS 2.18, ships with 7zip

usage on unix

Given you have an ALKIS NAS Konvoi, a set of compressed GML files like the following:

EcoLibro_20180313T000000_00von25_32400000_5585000.xml.gz
EcoLibro_20180313T000000_01von25_32400000_5585000.xml.gz
EcoLibro_20180313T000000_02von25_32400000_5585000.xml.gz
...
EcoLibro_20180313T000000_25von25_32400000_5585000.xml.gz

Run ./convert_alkis_nas.sh <input-nas-dir>. This will generate ./alkis_2018-03-13.gpkg file containing your data. Parameters to customize output filename, format, and SRS are available:

./convert_alkis_nas.sh <input dir> <outfile> <ogr driver> <out srs>

usage on windows

Place your NAS Konvoi input data files (*.gz, see above) inside the directory of this batch script. Run the convert_alkis_nas.bat script. alkis.gpkg will contain your data. No parameters are available.
