The first question which comes to mind is: why would you want/need this? We don’t have permission to copy data from Google. We are allowed to use Bing imagery and at a more local scale we have permission to use other imagery, but not Google’s.
As soon as we do get that permission (around the time hell freezes over or thereabout), you will see that it becomes a trivial option to use Google maps/imagery and whatnot.
Also, have a looksee at JOSM. It’s especially useful to be able to use the other more local imagery and that’s only one of the possibilities.
I realise the resolution is better and usually the images are also taken more recently. We’re creating a database with freely licensed data though, so it’s important to make sure it’s all done correctly, as we don’t have the funds to defend ourselves in a legal battle.
Where are you mapping, maybe there is an alternative supplier of imagery available.
The world is moving more and more towards open data, so if nothing is avalaible at the moment, it’s often only a matter of time.
The lack of free data sources does not give you permission to copy from copyrighted sources. If your edits are based on Google Maps, whether their street map or their satellite layer, then your edits will be deleted at the first opportunity. Don’t waste your time and ours.
