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.

Contents

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:

  1. Open Data Source Manager QGIS 3.0 datasource.png
  2. Click WMS/WMTS Addwms.png.
  3. Type a namme for the new WMS connection e.g. BKG DTK250(Digitale Topographische Karte 1:250,000, Bundesamt für Kartographie and Geodäsie, Frankfurt).
  4. Type the URL : http://sg.geodatenzentrum.de/wms_dtk250

Qgis add dtk.png

  1. Click OK
  2. Click Connect
  3. Now a list of all downloadable layers appears.
  4. Mark one of the layers and click Add

Add Google Maps layers

  1. To add the Google Maps map service in QGIS 3 simply, go to XYZ Tiles in the Browser panel.
  2. Right-click on XYZ Tiles and choose New Connection.
  3. Enter the name for the WMS Service fo example: Google Satellite
  4. Copy and paste the URL: https://mt1.google.com/vt/lyrs=m&x={x}&y={y}&z={z}
  5. Adjust the maximum zoom level 19.
  6. To view inside QGIS simply double-click or drag the XYZ Tile service to the layers panel.
  7. 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&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}
Carto Positron https://cartodb-basemaps-a.global.ssl.fastly.net/light_all/{z}/{x}/{y}.png
