Sometimes as a geospatial professional you want to find OGC and other1 geoservices endpoints being displayed in a web map. The “traditional” approach involves using your preferred browser’s developer tools to inspect the resources requested through network traffic.
With a new extension this task becomes a lot easier: When the Chromium-based Geo Hound extension is enabled, it automatically detects geoservices (and geospatial files such as KML/KMZ, GeoJSON, Shapefiles, and GeoTIFFs) on any webpage you visit. It then collects these in a convenient list for later use:

With Geo Hound, you can:
- Save detected services with automatic deduplication
- Test web compatibility with one-click CORS2 validation
- Normalize URLs for use in ArcGIS, QGIS, and other GIS applications
- Organize services with custom folders and notes
- Search and filter your collected services and files
- Disable detection on selected URLs or domains
- Export service information for team sharing
- Track service analytics with cloud database integration
A quick test shows that the extension works on, for example, map.geo.bs.ch, geo.so.ch/map, maps.zh.ch, geo.zh.ch/maps, zugmap.ch, and map.geo.admin.ch, not, however, on map.geo.tg.ch.
