<div> </div>
<div>Thanks so much for your enthusiasm, your response time is fantastic!</div>
<div> </div>
<div>I like PicLayer but using only 3 points I could never get the map to align properly (which is a defect of the map for sure). It works well for maps that are drawn more recently and dont need warping, e.g building outlines or archeological dig site maps.</div>

<div>PS: if you love these ortho layes, you will love these</div>

<div name="quoted-content">
<div>Hi Hannes -
<div> </div>
<div>I LOVE these layers. Thank you!!!</div>
<div> </div>
<div>This tweet contains diagrams that show how to add those layers (1 at a time) to iD: <a href="https://twitter.com/OpenHistMap/status/1279135482283085824" target="_blank">https://twitter.com/OpenHistMap/status/1279135482283085824</a></div>
<div> </div>
<div>The general problem you're describing (not having cool historic baselayers automatically show up in iD) could be solved by having an OHM-specific Editor Layer Index (<a href="https://github.com/osmlab/editor-layer-index" target="_blank">https://github.com/osmlab/editor-layer-index</a>) & having OHM's iD point at that. That's a brilliant idea. I've opened a ticket to do just that. It might actually be relatively easy, but "easy" things rarely are & still take work. : ) (<a href="https://github.com/OpenHistoricalMap/issues/issues/122" target="_blank">https://github.com/OpenHistoricalMap/issues/issues/122</a>) A cool side note: ELI works in JOSM with a small preference setting change. 2 for the price of 1.</div>
<div> </div>
<div>And, THANK YOU for editing the Wiki page. Fortune favors the bold, my friend!</div>
<div>(Piclayer can indeed be fussy, but with a little practice, it's pretty cool)</div>
<div> </div>
<div>Those Orthos are quite cool, as well.</div>
<div> </div>
<div>These are all awesome & exciting suggestions - I encourage others to share their thoughts and experiences and to check out Hannes' links.</div>

<br/>
Currently the default iD editor seems to have the same background<br/>
layers available as OSM and I currently dont see any customization for<br/>
OHM. I think it would be cool to have a few pre-set options to choose<br/>
from to get people started. I know this can be configured to be region<br/>
specific (for example if I go to Switzerland, Thurgau then the "Kanton<br/>
Thurgau OF 2017" shows up but nowhere else since these fotos are only<br/>
there for Thurgau) so it would be great to collect a bunch of<br/>
background tiles one could use.<br/>
<br/>
Digital Atlas of the Roman Empire (DARE):<br/>
<a href="https://dh.gu.se/tiles/imperium/%7Bz%7D/%7Bx%7D/%7By%7D.png" target="_blank">https://dh.gu.se/tiles/imperium/{z}/{x}/{y}.png</a> (CC BY 4.0, Europe<br/>
specific)<br/>
Sulzberger map:<br/>
<a href="http://warper.wmflabs.org/maps/tile/3271/%7Bz%7D/%7Bx%7D/%7By%7D.png" target="_blank">http://warper.wmflabs.org/maps/tile/3271/{z}/{x}/{y}.png</a> (CC0,<br/>
location-specific)<br/>
<br/>
I think this could help "newbies" quite a bit and give them a cool<br/>
place to start mapping. It could also help with attribution since we<br/>
could store what source information was used for each object and edit.<br/>
The least we could do is collect a few "interesting" layers on the<br/>
wiki and help newbies to get started.<br/>
<br/>
Of course eventually this could be location and time-period specific<br/>
and the "right" background map could just show up "magically" on the<br/>
right side for mapping.<br/>
<br/>
I know that this functionality already exists on the Warper side (eg<br/>
<a href="http://warper.wmflabs.org/maps//3271#Trace_tab" target="_blank">http://warper.wmflabs.org/maps//3271#Trace_tab</a>) but there are more<br/>
maps out there then what Warper has and some countries provide tiles<br/>
for historic maps. Have you previously thought about that?<br/>
<br/>
Secondly, it took me some time (and struggling with the very limited<br/>
PicLayer JOSM plugging that can only use 3 control points and seems to<br/>
do very limited warping) to actually find the Warper and the wiki page<br/>
<a href="https://wiki.openstreetmap.org/wiki/MapWarper" target="_blank">https://wiki.openstreetmap.org/wiki/MapWarper</a> is only mentioned once<br/>
in a long list of tools. I was bold and added this workflow to the<br/>
wiki page myself:<br/>
<a href="https://wiki.openstreetmap.org/wiki/Open_Historical_Map#How_to_trace_a_historic_map_in_OHM" target="_blank">https://wiki.openstreetmap.org/wiki/Open_Historical_Map#How_to_trace_a_historic_map_in_OHM</a><br/>
for other to find more easily<br/>
<br/>
Thirdly, just to bother you more with my usecase: the Swiss Cantons<br/>
provide access to Orthofotos layers and they have them historic!<br/>
(yay!). Now that may be a cool usecase for this to play around:<br/>
<a href="https://josm.openstreetmap.de/wiki/Maps/Switzerland" target="_blank">https://josm.openstreetmap.de/wiki/Maps/Switzerland</a> - for example grab<br/>
the<br/>
<br/>
Kanton Glarus Orthophoto 2013 {view}<br/>
Kanton Glarus Orthophoto 2015 {view}<br/>
Kanton Glarus Orthophoto 2017 {view}<br/>
<br/>
and you have historic 4 years of Orthophoto (Switzerland has these<br/>
going back to the 70s but probably not all under suitable licence).<br/>
<br/>
<br/>
<br/>
Best<br/>
<br/>
Hannes<br/>
