Today I wanted to present you, yammdb.
Which is another, different, geodatabase, based on real measurements.

You can find it here: https://github.com/Ne00n/yammdb
The Database is build weekly, on fridays.

As long the buildserver doesn't blow up.
The primary use case for me is to compare existing geo data, maybe someone of you will find it useful.

If you have any ideas and feedback, please lemme know.

Enjoy.
