How to Use Preview Map in FiberQ (QGIS Plugin) | PostGIS + pgAdmin4 + Docker
Preview Map in FiberQ is a live web map view of your fiber network that’s backed by a PostGIS database and served via a small Docker stack (PostGIS + pgAdmin4 + MapProxy/PHP).
It’s mainly used to review and share the latest network layers in a consistent “final map” view, and (optionally) make light edits that sync back to the server.
How to start Preview Map in FiberQ (step by step):
Request access from the FiberQ team:
an Activation/Unlock Key (enables Preview Map + Publish to PostGIS buttons)
the telecom-webmap_MAPPROXY server folder package
Install & run Docker Desktop, then start the stack from PowerShell inside the MapProxy folder:
docker compose up -d (and check with docker compose ps).
Connect QGIS to the PostGIS DB (Data Source Manager → PostgreSQL), then click Preview Map in FiberQ.
What Preview Map does inside FiberQ?
You can select one or more server layers in the Preview Map window and click “Load selected layer into project” to bring them into your QGIS project.
After loading, you can add/delete features and then use Refresh layers so the Preview Map reflects changes.
This setup is especially useful for larger teams and organisations, because multiple users can work against the same PostGIS database — reviewing the same layers and collaboratively adding new elements or updating/removing existing ones in a controlled, shared environment.
Important workflow detail: layers can appear as “(Database Layer)” (live server table) and also as a local/working layer. Toolbar tools usually add new features to the working layer; to push your local layer to the server you use Publish to PostGIS (which can also overwrite/recreate a server table).
