Hi John, While Bing imagery is probably the most commonly used imagery for tracing. There are a variety of other sources. For example, the State Department through their MapGive initiative (http://mapgive.state.gov/) often provides recent DigitalGlobe imagery for specific tracing tasks. Also, data might come from an import (and not having been traced from imagery). Having some sort of measure of "completeness" of OSM is a difficult question. What do you use for the denominator in the equation? Mikel Maron wrote a blog post that might be of interest ( https://www.mapbox.com/blog/how-complete-is-openstreetmap/). Sounds like you're working on a cool project. All the best, Dan
