This site is run by Jochen Topf and Christoph Hormann. You can contact us at email@example.com.
We love to hear from you if you have suggestions for this service or want to tell us how awesome it is. But please remember that we run this site in our spare time. We don't have the time to give you free advice on OpenStreetMap in general or how to use this data with your software. If you have questions on OpenStreetMap please use one of the many ways of getting support.
If you need advice, custom software development or visualization services and are willing to pay for it, we are available for hire. Get in touch!
