What's the purpose of this document?

This document sets out to answer the common questions which arise about the use of the OSGeo Trademarks and Logos. Our code is free, but we do strictly enforce our trademark rights; we must, in order to keep them valid. This means that, while you have considerable freedom to redistribute and modify our software, there are tight restrictions on your ability to use the OSGeo name and logos, even when built into binaries that we provide.

What are the OSGeo Trademarks and Logos?

The OSGeo trademarks include, among others, the names The Open Source Geospatial Foundation, OSGeo,, and the compass logo.

The OSGeo logo is displayed without the(R) symbols. TM in superscript can be added but it is not required (Thanks to Jennifer Daehler for this information).

Can I put OSGeo banners on my website? Can I link to you?

Thanks for your support -- of course you may. Please read how to put OSGeo banners on your website and how to link OSGeo.

Can I make a t-shirt/desktop wallpaper/baseball cap with the logo on?

Sure, if it's just for you, or if it's for others and no money or other consideration changes hands -- but note you are specifically precluded from producing items with the OSGeo name or logo for distribution at tradeshows, local user group meetings, etc. OSGeo operates the OSGeo store which sells a wide range of branded merchandise for exactly this purpose, with the proceeds going to support the Foundation. For more details please read Trademark Guidelines: Logos and Merchandise.

Can I modify your logos and distribute the result?
