While imports are bad for mappers, disallowing imports is
also bad for users. We had initially had a lot of enthusiasm for OSM and were
planning to integrate it into our editing workflows and applications.
When imports from our editing workflow were rejected, we
pretty much gave up. Our cartographer group hand edits just as much as a
volunteer mapper, including fieldwork, official documents, lidar, and aerial
photography in their workflow. We even have terabytes of GPS traces from our
patrol vehicles. When their contributions were disallowed, we were essentially
cut off from making any corrections to data that we knew was wrong. That
greatly decreased the value of OSM for us, and we stopped plans to use OSM for
new web applications. Obviously we completely halted plans to integrate it into
our editing workflows.
So yes, this strategy encourages new mappers, but having
to stare at bad data without being able to touch it also discourages us as a
new user. I suspect we are not the only group discouraged in this way.
