# Astun Technology GML/KML Loader

You can use the Astun Technology Loader to convert GML 2.1.2 data to other geospatial and non- geospatial formats.

This is a free, open-source loader for geographic data in GML and KML formats. It is written in Python and uses OGR 1.9. source data to output to any format supported by OGR, for example, shapefile and MapInfo TAB.

The loader was last updated in September 2022. Installation files and guides for the loader, including configuration examples, are available from the [AstunTechnology/Loader](https://github.com/AstunTechnology/Loader) GitHub repository.
