So this week, there are suddenly a lot of notes popping up across the Malaysian North - South Expressway and also some other Malaysian expressways.
I usually consider anonymous note (sometimes) are good because the number of OSM mappers from Malaysia is not that big.
However, recently, I have came across a navigation application that posts a note (anonymously) where OSM database seems to contain incomplete or wrong information - most of the time it is just because OSM data is incomplete here, but also there is something wrong with the app itself e.g. speed limit in x5 km/h (the Malaysian speed limit do not use a speed limit in fives i.e. 35 km/h; usually an increment of tens i.e. 40 km/h, 70 km/h, 90 km/h, 110 km/h is in enforcement). Well, the developer already has took an action and hopefully this would improve the OSM database in a more convenient way.
Fast forward to this week, now, that weird notes. Probably in this coming few weeks, I would have to “resolve” that comments. They are really strange, because it appears that the anonymous note contributor(s?) is totally new to OSM, or, is using the OSM database on a third-party device or some unknown navigation (or map viewer) apps. I could handle probably few notes but there are, like, hundreds of them!
Some of the inputs are good (but they are not properly attributed - signs of someone new to OSM but this takes time and learning curve); furthermore, some of them is stating what is already obvious on the map. This makes me feel furious, as if, that user is copying from somewhere else (hopefully not from a proprietary, non-free database) - which leads to the assumption that the user itself is not familiar with OpenStreetMap at all! Worse, that user probably do not know about OSM - sigh.
Hopefully that user is not copying from the crowd-sourced Malfreemaps (or Malsingmaps) database as it contains proprietary data.
