In the preferences, under "advanced", there is a setting called "simplify-way.max-error". It is important to set this to a low number appropriate for the specific geometry; in the case of a very clear lake like this, sub-meter precision can be maintained, hence a value of 0.4

Also, where two roads cross, they need to share a node. Please learn about connectivity.

Maykel, you used "service" incorrectly for the roads in the village. They are "residential" roads.

Also, never name roads just "jalan". The name tag is only for the actual name of the road, e.g. "Jln Poror Pinrang-Rappang"

Albert, you damaged the main Pinrang-Rappang highway by incorrectly changing the secondary to a service road. I will fix it now, but please be careful in the future.

Hi maraf24, I believe I only removed a few tags, which were uncontroversially incorrect or extraneous. If there is a page that describes the Wroclaw building import, please direct me to it.

@SomeoneElse, it depends :) In some places the legal boundary is defined as the river, in other places the river was surveyed and that description of the course defined as legal boundary. It takes local knowledge to know the difference in different parts of the world.

I reviewed it personally. There is decimation to remove noise and redundancy, but I also go over what remains manually to compare it to the aerial; many of these wetlands are no longer here and are adjusted accordingly.

I've proceeded to clean it up now.

This looks like a building import, but there were already buildings there. Was there no attempt to integrate and check for overlaps? Is there a plan to clean this up, or should I go ahead and clean it up manually?

Also, I notice that it isn't quite consistent; in some places the parish boundaries share a way with the river, in other places they use two separate ways; perhaps someone determined that on that stretch the "official" boundary differed significantly enough from the river. Some boundaries has the natural feature _as_ the official boundary, so in that case they should always share a way, but again, if you have local knowledge otherwise, you can make them consistent.

Hi tngpoint, mostly this changeset was fixing the riverbanks and adding the islands. The centerline moved only very slightly; it had a few places where it did not appear to correspond to the river flow. I did the best I could using the aerial, but if you have better local knowledge, please feel free to adjust it.
