WMS stands for Web Map Service. WMS produces maps of spatially referenced data dynamically from geographic information. These maps are rendered in a pictorial format for example PNG, GIF or JPEG. The operations can be done using a standard web browser which submitt requests in form of a URL. The OGC WMS specification standardizes the way in which maps are requested by clients and the way that servers describe their data holdings.

Clients
A growing number of clients supporting WMS or WFS standards.
- ArcGIS
- Quantum GIS
- UDIG
- OpenLayes - pure javascript library for displying map data in most web browsers
Requests
There are differnt types of requests, but only two are required by any wms server:
- GetCapabilities - returns parameters about the WMS and the available layers
- GetMap - with parameters provided, returns a map image
Add WMS layer
If you want to integrate a WMS-Layer to QGIS 3 follow these steps:
- Open Data Source Manager
- Click WMS/WMTS
.
- Layers --> New. Type a name for the new WMS connection e.g. BKG DTK250 (Digitale Topographische Karte 1:250,000, Bundesamt für Kartographie and Geodäsie, Frankfurt).
- Type the URL : http://sg.geodatenzentrum.de/wms_dtk250
- Click OK
- Click Connect
- Now a list of all downloadable layers appears.
- Mark one of the layers and click Add
Add Google Maps layers
- Open Data Source Manager
- To add the Google Maps map service in QGIS 3 simply, go to XYZ Tiles in the Browser panel.
- Right-click on XYZ Tiles and choose XYZ Connections New.
- Enter the name for the WMS Service fo example: Google Satellite
- Copy and paste the URL: https://mt1.google.com/vt/lyrs=s&hl=en&x={x}&y={y}&z={z}
- Adjust the maximum zoom level 19, confirm with OK.
- To view inside QGIS go to the Browser panel. Unfold the XYZ Tiles and double-click or drag the XYZ Tile service to the Layers panel.
- Configure additional WMS connections in the same manner using the URLs of this table:
| WMS Name | URL |
|---|---|
| Google Satellite | https://mt1.google.com/vt/lyrs=s&hl=en&x={x}&y={y}&z={z} |
| Google Streets | https://mt1.google.com/vt/lyrs=m&x={x}&y={y}&z={z} |
| Google Terrain | https://mt1.google.com/vt/lyrs=p&x={x}&y={y}&z={z} |
| OpenStreetMap Mapnick | http://tile.openstreetmap.org/{z}/{x}/{y}.png |
| OSM Cycle Map | http://tile.thunderforest.com/cycle/{z}/{x}/{y}.png |
| OSM Black and White | http://tiles.wmflabs.org/bw-mapnik/{z}/{x}/{y}.png |
| Bing Maps | http://ecn.t3.tiles.virtualearth.net/tiles/a{q}.jpeg?g=1 |
| ESRI Streets | https://server.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer/tile/{z}/{y}/{x} |

Add Digital Ortho Photos (DOP) of Lower Saxony
- Open Data Source Manager
- Click WMS/WMTS .
- Layers --> New. Type a name for the new WMS connection e.g. BKG DTK250 (Digitale Topographische Karte 1:250,000, Bundesamt für Kartographie and Geodäsie, Frankfurt).
- Type the URL : http://sg.geodatenzentrum.de/wms_dtk250
- Click OK
- Click Connect
