When you have no previous mapping experience, then starting with Thailand is a … problematic choice. Originally, it was rather a project of “farangs” mapping in Thailand, without a real local mapper community. And unfortunately, many farang mappers seem to have little experience with mapping in their - generally well mapped - home countries. I am sure that many road classification issues would not exist if many of us just looked at the classification in their home countries. I saw many an “unclassified” road in Thailand with much higher technical standards, performance, and importance in the road network than some “secondary” in Germany (a country said to have one of the best road networks in the world…).
Later on, more people without previous mapping experience added a lot of data, e.g. paid by Facebook. They learned from the bad mapping before, and - without any experience with the possible conflicts of imagery and ground truth - added really problematic data…
I am not content with the current situation. I try to get the best out of the data, by creating my own maps, rather than getting involved in edit wars. We lost a very productive mapper who drove around in the Thai province where he lives and collected enormous amounts of ground truth data after an edit war.
