<div dir="ltr">Hi Kathleen!<div><br></div><div>Thank you for your answer! I've read the community guidelines, but it is still not perfectly clear to me, that if I generate game worlds using OSM data, then am I forced to publish any data, or open source my game engine? Is it enough to just acknowledge that the data is from OSM?</div><div><br></div><div>I feel that this sentence applies for my project as well, but I am not really sure:<br><i>"We feel there are situations where you may be manipulating OpenStreetMap data but are not actually adding to or enhancing the core contributions made by our contributors. Therefore we feel there is no common good to be served by forcing you to publish the result of those manipulations."</i></div><div><br></div><div>It also mentions that <i>"provided that no other source of data is involved"</i></div><div>I also use heightmap and weather data from different sources, to generate the game world. But those datas are not my property, and can not be contributed back to OSM.</div><div>So I don't use any other data, which could enhance OSM, or which could be contributed back.</div><div><br></div><div>Sorry for the many questions, but legal texts are confusing for me, especially because english is not my first language.</div><div><br></div><div>Thanks,<br>Lucas<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">Kathleen Lu via legal-talk <<a href="mailto:legal-talk@openstreetmap.org">legal-talk@openstreetmap.org</a>> ezt írta (időpont: 2021. febr. 10., Sze, 22:21):<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Hi Lucas,<br>

> I would like to develop a game, which uses OpenStreetMap data to generate game maps, and game assets ( like 3D models ). The 3rd point of Legal FAQ is a bit confusing to me. Are the generated objects considered as "Derivative Database"? Is it enough to clearly acknowledge, that I use OSM data in the game? The OSM datas are not altered, but a completely new dataset is generated from it.<br>
><br>
> I've found a similar question in the wiki, about "using OSM data in a computer game together with other data sources". It states, that "OK as long as the games company also provides an offer of the open derivative DB free from technical measures in parallel. Otherwise, its explicitly disallowed."<br>
> Is the "derivative DB" the subset of openstreetmap data, that I use in the game? Or does this also include the generated game objects, and the algorithm to generate them as well?<br>
> Does "provides an offer" mean, that I can charge the development costs ( or more ) for someone, who wants to acquire the game files in an accessible format?<br>
><br>
> I do not wish to make the generated objects ( 3D models, game maps, etc...) freely available, and I also could not afford to open source the game, and the code, which generates the game objects from OSM data. It would mean, that anyone could get a free copy of my work.<br>
><br>
> What if I convert the required OSM data to a proprietary format first, and then import that in the game? In that case, the game could even work with other sources, which produce that proprietary format, not just OSM.<br>
><br>
> What if the game objects are generated on a server and sent to the players machine, when they visit a new area in the game? There is not really a constant database then, but an ever changing one.<br>
><br>
> There are some commercial games available, which use OSM data, like Pokemon Go, 911 Emergency Manager, etc... I am not able to find any website or offer, where folks could download their derived databases. How did they solve it?<br>
