Copyright - Using Maps in Printed Publications

Hey everyone. I’m new here. I create homeschooling content for grade school students, and it’s amazing that I just found this! Such a game changer for teaching history. That being said, I don’t really understand how the copyright works. I want to be able to generate a map, say of Europe just prior to WWI. Then, I want to download the map and include it in my written material which is for sale. Can I do this?

Hi Nicholas, glad you found us! Yes, you’re more than welcome to use OHM data in your products. We offer multiple ways to access and reuse the data. Let us know if you need the data in a particular format or geared toward a particular curriculum.

OHM is dedicated to the public domain. This means you can literally do whatever you want with it, even reuse it commercially. There is one caveat: a relatively tiny number of boundaries, buildings, etc. are copyrighted but licensed for reuse with some conditions (typically a requirement to credit the original source). These exceptions are indicated by the license=* tag on each individual feature.

We kindly request, but do not legally require, that you somehow give credit to OpenHistoricalMap as a source. This helps us get the word out but could also help you establish trust with parents who want to do their due diligence.

Looking forward to seeing what you create with OHM!

Thanks! The one thing I haven’t figured out how to do is render all the country names in English…

If you’re getting the data using the Overpass API (such as through Overpass turbo, Overpass Ultra, or the QuickOSM plugin for QGIS), then many of the boundary relations have a name:en=* tag alongside the name=* tag. If you’re using the official vector tiles, unfortunately, the tiles don’t contain name:en=* tags yet.
