QGIS Server Quickstart

QGIS Server provides a web map service (WMS) based on libraries from the QGIS desktop application.

This Quick Start describes how to:

• update an existing QGIS project and render it with QGIS Server
• create a new QGIS project and open the WMS directly in a browser

Documentation:

• https://docs.qgis.org/3.4/en/docs/user_manual/working_with_ogc/server/index.html

Quick start for Server Installation on Debian/Ubuntu:

• apt-get install qgis-mapserver libapache2-mod-fcgid
• -> http://localhost/cgi-bin/qgis_mapserv.fcgi

QGIS Web Client:

• https://github.com/qgis/qgis-web-client

Start GeoExt viewer

OSGeoLive contains an example of web map viewer based on the GeoExt Javascript framework and using QGIS Server for rendering the map.

• Click Geospatial ‣ Web Services ‣ QGIS Server

You should see a browser window with a web map viewer showing a world map.

Alternatively, you can access the application using a browser through http://localhost/qgis_server

We will now change the map styling using QGIS.

Edit QGIS project

1. Click Geospatial ‣ Desktop GIS ‣ QGIS.
2. Choose Project ‣ Open… from the menu bar.
3. Select QGIS-NaturalEarth-Example.qgs and press Open.
   • You should see the same world map rendered by QGIS. We will now change river styling and look at the result in the web map viewer.
4. Double click ne_10m_rivers_lake_centerlines in the Layers tree.
5. Change the color in Outline Options to a different blue tone.
6. Press OK.
   • Rivers are now rendered in a new color.
7. Save the project with Project ‣ Save.
8. Reopen the web browser
9. Zoom in
   • You should now see rivers rendered in the same new color.

Create a new QGIS project

1. Reopen QGIS
2. Choose Project ‣ New.
3. Click Layer ‣ Add Vector Layer….
4. Browse to dataset /home/user/data/natural_earth2/ne_10m_admin_0_countries.shp.
5. Press Open.
   • You should see all world countries.
6. Save the project with Project ‣ Save.
7. Use file name /home/user/world.qgs and press Save.
8. Open the WMS URL.
   • You should see all world countries, this time rendered by QGIS Server.
