OT: Free Online Map Software for Net54 Card Project
 

I have an idea for a project. To pull it off I will need free online map software with the ability to add a lot of layers and hopefully sublayers.

Any recommendations?

Thanks

Try this on Google Maps?

Note, creation only available in Desktop version, not Android nor iPad/iPhone.

Sorry - should have added this: Google Maps seems not to allow more than 10 layers and does not allow any sublayers, both of which I would want.
