Convert GML to OSM

What is GML file?

The GML ( *.GML ) file type is the standard document format for Geography Markup Language (GML), developed by the World Wide Web Consortium (W3C). The file extension saves geographic features in an XML file, enabling the development of a range of programs and applications that read and reprocess this data. The format is part of the wider GML technology, which includes implementations for ESRI's ArcGIS and Google Maps, allowing data to be cross-referenced and exchanged between these applications.

What is OSM file?

The OSM file extension stands for OpenStreetMap Map File which is an open-source vector data format used for editing and storing geographical information. It adheres to the XML standard, using GPS Exchange Format (GPX) to encode points, lines and polygons on a digital map. OSM map data is stored in a hierarchical structure called nodes, which are connected together by waypoints to represent spatial relationships between elements. [ ⏩ ] OSM file extension

How to convert the file from GML to OSM?

To successfully convert the GML file to OSM, you should install one of the applications from the list. After installing the software, open the program and select the file you want to convert (file-name.GML). The next step is to select the target format from the list, in this case OSM (usually converters allow you to convert to several different formats, so check out their features - maybe one of the available formats will suit you more than OSM).

What is a file conversion?

A data conversion is normally an automated process to some extent. The effect of the operation of one program is automatically the input product of another application. If that does not happen we need to help the process a little bit and convert the file on our own, e.g. GML to OSM. To obtain a matched structure of the data, it is necessary to use an appropriate converter.

Program for converting GML files to OSM files is a kind of a "binary code translator" compensating for the differences in the code or translating it in such a way so that another application could use it. For us, as users, the visible change will be only another file extension. (After converting the file, it will be the extension OSM, while before this step we had the GML file). For the programs, the difference is on a much higher level – either the application will be able to open a new OSM file, or not.
