It really is a concept deeply connected with our culture, that's why the Sierras are everywhere in our topographic maps [1], and that's why the spanish OSM community agrees with the importance of having all of Sierras correctly represented in OSM, at the same level as rivers, lakes, cities or regions.</div><div dir="auto"><br></div><div dir="auto">Having said that, we are going to import just two elements for each Sierra:</div><div dir="auto"><br></div><div dir="auto">A) Name</div><div dir="auto">B) Location</div><div dir="auto"><br></div><div dir="auto">Regarding the verifiability of the names, I think it's already clear that we are using the defacto standard names for our Sierras. Sierras are not temporary elements, they have been there for eons, and their names haven't changed for centuries. Our official maps reflect that names, but yes, as any other source of the world, they could contain mistakes, of course. However, that could hardly be used as an argument against the import, in my opinion. On the contrary, that's the very nature of OSM: mistakes can be corrected and incompletion can (and must) be completed.</div><div dir="auto"><br></div><div dir="auto">Regarding the verifiability of the location, again, please keep in mind that we are going to map the Sierras as nodes, and exact spacial accuracy is simply not expectable nor aplicable here. We have been discussing this aspect in the spanish community and we simply accept that, because it's true nature, it's not possible to delimitate the exact location and limits of a Sierra (or a city, for that matter). However, that doesn't mean that Sierras don't exist or that they shouldn't be represented in OSM, a map without Sierras is an incomplete map, just as a map without cities or rivers: they are essential elements on our maps and we need to represent them the best way we can.</div></div><div dir="auto"><br></div><div dir="auto"><div dir="auto" class="elided-text"><blockquote style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="auto"></div><div dir="auto">And "we copy official data, everything else<br></div><div dir="auto">will be reverted, changes are not allowed"<br></div><div dir="auto">is not a good solution.<br></div></blockquote></div></div><div dir="auto"><br></div><div dir="auto">Nobody has said that. We are not trying to provide definitive and untouchable data here, we are just trying to fill an important gap on our map with the best and more reliable data source we have at this moment. But as stated before, if someone in the future can provide better data from better and more reliable sources, the information on the database should be changed accordingly, of course.<br></div><div dir="auto"><br></div><div dir="auto">[1] <a href="https://wiki.openstreetmap.org/wiki/ES:Importaci%C3%B3n_NGBE_Alineaciones_monta%C3%B1osas#/media/File%3AEjemplo_Importaci%C3%B3n_mountain_range2.png" style="text-decoration-line:none;color:rgb(66,133,244)">https://wiki.openstreetmap.org/wiki/ES:Importaci%C3%B3n_NGBE_Alineaciones_monta%C3%B1osas#/media/File%3AEjemplo_Importaci%C3%B3n_mountain_range2.png</a></div></div></div></div></div></div><div dir="ltr" class="gmail_attr"><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div> </div>
