The buildings are over-generalized by either combining buildings, creating polygons much larger than the actual building, often the shapes are very crude and are not carefully formed with right angles, many buildings are skipped or overlooked, many are overlapping with other buildings or roads, and in many cases create self-intersecting polygons</div><div>8) Once a mapper starts with these bad habits the habits are picked up by others working at the same time which expands the problems</div><div>9) It appears that after a small number of edit sessions the mappers from these efforts do not continue with other HOT tasks, and presumably go a way thinking they have done their feel-good-humanitarian-service.</div><div><br></div><div>The net result of these mapathons is that rather than contributing to the completion of mapping in an area, there is actually more work required to clean up the messes than there would have been to properly trace the features from scratch.</div><div>I do not believe this is a validation issue, but is an issue with leadership. The individual organizing the event for the corporation or group may have little or no OSM experience, and have been giving the task of setting up the mapathon and do not have the skills or expertise to help newbie mappers. I also have seen people that claim to have OSM experience or skills often are very inexperienced and have very slight exposure, There is a lot to learn about OSM, and we do ourselves a disservice by saying that it's easy and anyone can do it. We should be happy to teach people, but I don't believe any of us doesn't have more to learn.</div><div>I have led several corporate mapathons in person and remotely, they are hard work.

Important to note the guidelines are suggestions not enforced requirements of the OSMF.

Data quality needs to become a primary focus of these and other mapping activities asap. Otherwise it’s not valuable experience for those present or everyone else working with OSM data.
