Today GeoServer is an open‑source solution recognized for publishing and sharing geospatial data on the web, compatible with a wide variety of formats and open standards, which allows organisations to disseminate their cartographic information easily without high licence costs and with strong interoperability.
What problems does GeoServer solve?
GeoServer meets the needs of developers, system administrators and IT specialists who want to publish, visualise and query geographic data from different data sources while respecting industry standards. Unlike proprietary, often expensive or vendor‑locked solutions, GeoServer offers a free alternative originating from an open‑source project, enabling smooth integration into existing GIS architectures and guaranteeing standardised data dissemination through widely adopted open protocols.
Key features and capabilities
Publication and interoperability
GeoServer supports several OGC standard protocols such as Web Map Service (WMS), Web Feature Service (WFS), Web Coverage Service (WCS) and Web Map Tile Service (WMTS), providing high compatibility with GIS clients like QGIS, OpenLayers or Leaflet, thus facilitating interoperability between tools and platforms within an open‑source service oriented toward map distribution.
Data sources
GeoServer can connect to a broad range of geospatial data sources, including databases (e.g., PostGIS, Oracle Spatial, MySQL) and file formats (Shapefiles, GeoTIFF, PNG), offering great integration flexibility.
Interface and customisation
The tool provides a browser‑based management interface that simplifies the administration of data layers, styles and published services without needing complex configuration files.
Security and control
By serving data as images via protocols such as WMS or WMTS, GeoServer shields the source data from unauthorised direct access, thereby strengthening the security of published spatial data.
How to install and configure GeoServer?
Download the latest stable version from the official website.
Install GeoServer on a Java‑compatible server, such as Linux or Windows.
Access the web administration interface to configure your data sources, workspaces and layers.
Customise styles and OGC services according to your needs.
Use cases for GeoServer
• A local authority uses GeoServer to publish water‑network and sanitation maps on GIS web portals, improving transparency and intervention planning thanks to an active open‑source community and proven tools.
• An environmental‑analysis company deploys GeoServer with PostGIS to serve raster and vector data to an interactive mapping application, benefiting from the robustness and longevity of a mature open‑source ecosystem.
