GeoServer — The Complete Guide: Free Publishing of GIS Layers as WMS and WFS Services
GeoServer is an open-source map server, an OSGeo project, that publishes spatial data from a database or files as services in the open OGC standards. Any software that reads those standards — QGIS, ArcGIS or a web page — connects directly.

- WMS — rendered maps as images, for fast display.
- WFS — vector features with attributes, including editing.
- WCS and WMTS — rasters and fast map tiles.
- Data sources — PostGIS, shapefiles, GeoPackage and GeoTIFF.
- Styling and permissions — server-side styles, plus user and layer management.
Why it matters in an engineering office
Instead of emailing files and discovering everyone holds a different version, you publish one utilities layer that everyone reads from. GeoServer also bridges a PostGIS database to field tools such as QField. The real cost is maintenance: you install it on your own server (Java), and someone has to handle updates, backups and security.
