OpenStreetMap 開放街圖
So today I started mapping my most visited places, Luanda, Kitwe, Windhoek, and a bit of Lusaka. Luanda as of now looks like a huge twisted net with no direction - and the plan is making sure the place ends up being as precise as possible.
New areas of Windhoek, NAM and Kitwe, ZAM, are also being corrected.
Let’s see what’s going to happen. Really looking forward to seeing my updates on Maps.me.

Updates for me happen quicker on Andosm …
However .. I now don’t look for my changes so much on my device. I do look back at them to check for errors (mine!) using the main web map.
Precision. Well yes to some degree. However it is more important to convey what is on the ground with a reasonable relationship between them. For example … a road curve might be represented as a single node precisely located at the apex. The map would then be a very sharp junction of two lines. Precise - yes, representative? Probably not .. needs more points to represent the curve that is there. Even if those points are not precise, they are a better representation of what is there. So don’t be too concerned with the precision, representation is more important.
