How to Add Google Map Layer on Quantum GIS Using Google Layers Plugin

In some cases, we want to add google map layer to our GIS project. We could add directly google map layer into our GIS project using Quantum GIS (QGIS) by Google Layers plugin. Using this plugin, we could add Google layer including: Road Map, Mobile Map, Terrain Map, Satellite, and Hybrid. The layer that is added by Google Layer plugin is treated as raster layer, so if we pan or zoom in or out we should add the layer manually. How to install and operate the Google Layer plugin on Quantum GIS (QGIS)? just follow some steps below:

  1. Click on Plugins menu
  2. Click Fetch Python Plugins
  3. Click Repositories
  4. Click Add 3rd parties repositories
  5. Click Plugins (beside Repositories)
  6. Click/choose Google Layers plugin
  7. Click Install plugin
  8. Close Fetch Python Plugins window
  9. Click Settings menu than click Project Properties, (on new version of Quantum GIS, Project Properties is located at File menu)
  10. Type 900913 beside Find, then click Find, so Google Mercator will be highlighted. Then click OK. On some old version of Quantum GIS, Google Mercator is not available in the list, so you should add manually Google Mercator coordinate reference system on Settings > Custom CRS, give the name of the custom CRS (Custom Reference System) what ever you like, for example give the name Google projection, and in the parameters fill with +proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids=@null +no_defs then save it by clicking floppy disc button, after that click OK. On the Project Properties you could choose Google projection CRS at User Defined Coordinate Systems
  11. Zoom to the area that we want to add Google Layers
  12. Click on Plugins menu > click Google Layers > Settings. Choose layer type that you want to view then click OK
  13. Click on Plugins menu > click Google Layers > Google Layers
  14. If you make a correct configuration, the Google Layers will appear on Quantum GIS
