Clifford and Nathan:  Nor did I "misunderstand" or "jump to the conclusion" that "the import had already occurred."  Nothing in my post even implied that.

Not only is the data useful in OSM, it can be used to help other community members learn the policies, tools and techniques to import data properly into OSM, in a way that improves the map. There are even some smaller towns that could be import by a single individual. Certainly not California!

As somebody who has CAREFULLY done imports (both before and after our guidelines were published), the most important consideration that I have is that the data enter OSM with the utmost, highest possible quality.  This means vetting them before, making sure they go in correctly (during) and checking after that they entered as intended, among very many other quality-oriented processes.

There are a great number of tools that can be used to extract smaller chunks of data such as QGIS and PostGIS as well as python scripts from other imports, like the LA address and building import. The US Tasking Manager is a great tool to use to 1) work small chunks at a time by people with training in how to use JOSM and OSM and 2) a built in validation layer for more experienced mappers to review the work.

Thanks, Clifford, I most certainly agree.  Tools help, yet tools are not all there is.  Tools can sometimes be leaned upon too much as a crutch, and data imports are not like pulling the trigger on a machine gun, whether to vet, upload, or data-check.  Having a practiced eye towards what high quality geographic data actually look like (both before and after upload to OSM) is absolutely essential to anybody acting in a leadership capacity during an import.

Spirited discussion!
