Might have messed up st agnes

Posted by hhg1405 on 29 January 2022 in English (English).

Hey everyone, I’m a casual mapper who decided to click on the list of 952 issues with my preferred region of Sainte Agnès (Ardencia). Ever since then, the Passage de Matchicoumi body of water has disappeared, and the surrounding area experiences major flooding errors.

Here is what I think happened. Among the unconnected paths and the overlapping roads, there was also ‘outdated tags’ and ‘missing role’. Now, as I said, I am a casual mapper, meaning I have no idea what relations are or what tags do. So, determined to shorten the list of issues with the region, I upgraded the tags of the coastlines and gave the line of an island (île de Mars) the role of ‘outer’ in relation to water. I had no idea what any of this meant, but I did it hoping to cut down on that issues list. Ever since, bodies of water have disappeared and solid land becomes water on different zoom levels.

So, my point is, I think I screwed up, unless this is a bug that will go away with time or maintenance. Either way, It would be great if a more experienced mapper went and checked on the situation so I don’t end up destroy another mapper’s hard work by making their body of water disappear.

Coords approx ‘-44.7505,153.8511’.

I have fixed the various relations. Thanks for reaching out.

Two suggestions - be very wary of relations until you have built up knowledge and are more comfortable using them first off for your own mapping.

Second - I would use a list of issues (presumably from iD?) to drive your mapping!

Just for clarification:

If you make a lake containing an island:

a. you should make a multipolygon with lake characteristics.

b. the lake shoreline should be ‘outer’ limit (role) of the polygon

c. the island shoreline should be the ‘inner’ limit (role) of the polygon

happy mapping !

I missed a not from my second point…
