Dear Jeff and others Currently the default iD editor seems to have the same background layers available as OSM and I currently dont see any customization for OHM. I think it would be cool to have a few pre-set options to choose from to get people started. I know this can be configured to be region specific (for example if I go to Switzerland, Thurgau then the "Kanton Thurgau OF 2017" shows up but nowhere else since these fotos are only there for Thurgau) so it would be great to collect a bunch of background tiles one could use.
Digital Atlas of the Roman Empire (DARE): https://dh.gu.se/tiles/imperium/{z}/{x}/{y}.png (CC BY 4.0, Europe specific) Sulzberger map: http://warper.wmflabs.org/maps/tile/3271/{z}/{x}/{y}.png (CC0, location-specific) I think this could help "newbies" quite a bit and give them a cool place to start mapping. It could also help with attribution since we could store what source information was used for each object and edit. The least we could do is collect a few "interesting" layers on the wiki and help newbies to get started. Of course eventually this could be location and time-period specific and the "right" background map could just show up "magically" on the right side for mapping. I know that this functionality already exists on the Warper side (eg http://warper.wmflabs.org/maps//3271#Trace_tab) but there are more maps out there then what Warper has and some countries provide tiles for historic maps. Have you previously thought about that? Secondly, it took me some time (and struggling with the very limited PicLayer JOSM plugging that can only use 3 control points and seems to do very limited warping) to actually find the Warper and the wiki page https://wiki.openstreetmap.org/wiki/MapWarper is only mentioned once in a long list of tools. I was bold and added this workflow to the wiki page myself: https://wiki.openstreetmap.org/wiki/Open_Historical_Map#How_to_trace_a_historic_map_in_OHM for other to find more easily Thirdly, just to bother you more with my usecase: the Swiss Cantons provide access to Orthofotos layers and they have them historic! (yay!). Now that may be a cool usecase for this to play around: https://josm.openstreetmap.de/wiki/Maps/Switzerland - for example grab the Kanton Glarus Orthophoto 2013 {view} Kanton Glarus Orthophoto 2015 {view} Kanton Glarus Orthophoto 2017 {view} and you have historic 4 years of Orthophoto (Switzerland has these going back to the 70s but probably not all under suitable licence).
