Why can't I use google maps?

This application is designed for use with the openstreetmap project. There are legal and ethical arguments not to use Google Maps when rectifiying and processing out of copyright maps. However, in my opinion you can use Google Satellite, so you may see a way to add this later.


Grab the wms link and paste that into the relevant place using the wmsplugin. Have a look on the openstreetmap wiki for more info.

Can I get the code and help?

Yes. you can get the code here: it's currently MIT licenced
. You can contact me, Tim Waters, by mail at
