= Main menu > WMS =

This menu item is only available when the wmsplugin plugin has been installed. 

The wmsplugin allows you to use various sources as a background layer in the main window.  Clicking on a green WMS menu item will automatically download the image from the server. Servers can be added and edited using the WMSplugin Preference Tab  in the [wiki:Help/Action/Preferences preferences ]. Any new servers or changes would then displayed on the main WMS menu. By default, Landsat and NPE menu items are added.

At present, the Menu has five sections: 

== Landsat ==

Downloaads Landsat image for the area.

== NPE Maps ==

Only applicable to England & Wales. Downloads a scanned and rectified image of the New Popular Edition Ordnance Survey map.

== Metacarta ==

== Rectified Image ==  
For use with Metacarta's [http://labs.metacarta.com/rectifier/ Map Rectifier]. Clicking on this opens up a dialog box requesting an id. The id is obtained from either the page url or the WMS link. (for example, 
http://labs.metacarta.com/rectifier/rectify/73 -  the id would be 73)

Note if you are using these images for editing then you need to ensure the image, and its method of rectification, are free of any copyright issues.

== Help == 
Opens up a text helpfile.
