GeoPulse Inspector: find the services behind any web map
A free Chrome extension that detects ArcGIS REST, WMS and WFS services in any map viewer and exports them to QGIS.
The challenge¶
Municipal and ministry viewers draw their layers from services that are almost never visible. Finding them to reuse the open data in QGIS normally means digging through browser developer tools.
The solution¶
I built an extension that does it for you. Open a viewer, click the icon and see a list of layers with plain-language names and a Save button.
- Detect: ArcGIS REST (FeatureServer, MapServer, ImageServer), WMS and WFS, including requests made before the extension was opened.
- Clean: resolves proxies, normalises URLs, drops basemaps and analytics noise, and never stores tokens or keys.
- Export: an inventory per project, with GeoJSON and live QGIS layer files (.qlr).
Results¶
- From open viewer to loaded QGIS layer in a few clicks
- Runs locally: no account, no server, no data leaves the computer
- Open source under the MIT licence
