GML Tools

GML (Geography Markup Language) is the OGC XML standard for geospatial features. It is the wire format for OGC Web Feature Services (WFS) and the canonical format for European INSPIRE data, government cadastres, and many municipal data portals.

This page lists every GML-aware tool on QuickMapTools: viewers, geometry operations, and converters to and from every common GIS format. Everything runs in your browser.

Frequently asked questions

What is GML used for?

GML is the OGC XML standard for geospatial features. You will most often see it as the response format from WFS (Web Feature Service) endpoints and as the canonical format for European INSPIRE and many national cadastre datasets.

Is GML still used in 2026?

Yes — heavily in European government, INSPIRE, and cadastral data. Less common in commercial web mapping, where GeoJSON dominates.

How do I convert GML to Shapefile?

Use the GML to Shapefile converter. Drop the .gml file, download a zipped Shapefile.

Why is GML so verbose?

GML is XML and explicitly types every feature, geometry, and coordinate system reference. It trades file size for self-description. Convert to GeoJSON or GeoPackage if file size matters.
