OpenStreetMap
I have been working with the JOSM plugin building_tools ( osm.wiki/JOSM/Plugins/BuildingsTools ). I only discovered it a few days but it is making my building-tracing tasks faster by a factor of 5 to 10. What a great tool!
I am noticing, however, that the resolution of Yahoo imagery using Potlatch 1.4 is much better than the Yahoo imagery available in JOSM. I'm wondering how I can get better resolution Yahoo imagery in JOSM to match what is available in Potlatch 1.4. I have created a short video ( http://youtu.be/TxRWIBd9lW4?hd=1 ) describing the problem and would love to hear feedback from others about how to accomplish this.

Good job with the video. You might want to post it on the wiki help page also. Sometimes if you zoom in first then load the wms imagery you get a better quality. Also if you are just doing buildings you can turn off the osm layer if you know you don't have anything there yet. The osm layer can add a film over the wms making it hard to add buildings. Also try the usgs wms layer which may be of higher quality.

Try zooming in, then right click "Yahoo Sat" in the layers tool on RHS of JOSM and select "Change resolution". Hope that helps.

JOSM and Potlatch do not use the same Yahoo API. Potlatch is written in Flash therefore uses the same Flash API. There is AFAIK no easy way to change this in JOSM. There is also no reason to change it, as we'll have Bing imagery in a week or two which is better resolution than Yahoo's imagery anyway.

"the Flash API", I mean, not "the same Flash API". (JOSM uses the JavaScript API.)
