Hi all, we have been exploring the possibility of adding default XYZ maps to QGIS, so to make life far easier for users. The good news is that the OSM board is quite positive about this. The not-so-good news is that their (I believe reasonable) requirements imply some more development from our side. Is anyone interested in taking this? Requirements below. All the best. ===
1. You seem to be using an user agent of "Mozilla/5.0 QGIS/2.18.3". We strongly recommend that you don't pretend to be a browser by adding the "Mozilla" bit. OpenStreetMap sees increasing traffic from "fake" user agents, and it is likely that we will penalise user agents like that at some point in the future - meaning tiles will still be served, but slower than to "honest" user agents that don't pretend to be a browser when they are not. We understand that this is difficult terrain and that other data sources might actually *require* that you pretend to be a browser - perhaps per-datasource overrides of the user agent are a possibility. 2. As you know, OpenStreetMap thrives on contributions by mappers, and one of the main reasons we make our tiles freely available is the hope of attracting new contributors. It would be nice if QGIS could do its part to help us here, by making their users aware that OSM is open for everyone to contribute. Perhaps a link to http://www.openstreetmap.org/fixthemap can be placed somewhere in the layer description or something. 3. Our data is licensed under ODbL 1.0, and our map tiles are CC-BY-SA 2.0. The latter could change at any time; the former is relatively constant. The legal consequences of this situation for your users are: * If they publish an image in which our tiles are visible, they must attribute OpenStreetMap as the source, and specify that the map image is CC-BY-SA 2.0, and specify that the data behind it is ODbL 1.0. All these requirements can be fulfilled in one go by linking to www.openstreetmap.org/copyright but there is no legal requirement to link to that page. * Everyone is allowed to create derivatives of OpenStreetMap data - for example by tracing features on the OSM tiles - and freely distribute them. Such derived datasets, unless they are "insubstantial" (https://wiki.osmfoundation.org/wiki/Licence/Community_Guidelines/Substantial_-_Guideline) inherit the ODbL license and must, when publicly used, on request be made available under ODbL. 4. If the load coming from QGIS should be unexpectedly high and impact our service performance, there might come a time where we'd have to throttle or even switch off this access. You should have some mechanism or plan that deals with that to avoid frustration among your user base - maybe a mechanism where QGIS installations request updated tile sources from a central service so you could notify them of the OSM tiles not being available (or being available elsewhere) should the need arise. -- Paolo Cavallini - www.faunalia.eu QGIS & PostGIS courses: http://www.faunalia.eu/training.html https://www.google.com/trends/explore?date=all&geo=IT&q=qgis,arcgis _______________________________________________ Qgis-developer mailing list [email protected] List info: https://lists.osgeo.org/mailman/listinfo/qgis-developer Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-developer
