Re: [talk-au] Suburb boundaries
I'm making some progress fixing up Perth suburb boundaries - honestly I'm finding it painful to untangle some of the changes, but I'm getting there. Looking further South I came across the relation for Burekup which was missing some of it's boundaries. OK, I think, I'll undelete the ways and it'll be easy. That led me to changeset 3790790 where the boundary had been deleted and from there to a number of other changesets by the same user (all without any comment). Here's the ones I found that affect boundary ways: http://www.openstreetmap.org/browse/changeset/3790790 http://www.openstreetmap.org/browse/changeset/3814003 http://www.openstreetmap.org/browse/changeset/3813839 http://www.openstreetmap.org/browse/changeset/3838876 There could be others, I didn't look through everything he's done. I have sent the user a message asking what he was trying to do but I'm not hopeful. Any suggestions about what to do before trying to manually repair?

I know some care about these so I hope to have OSM files up soon for them similar to the postcode files so that we can fix things up. I've been trying to fix up some of the suburbs in Perth that are missing on the suburb display map and running into some problems: * Some of the relations seem to be completely missing. * some boundaries seem to be duplicated (and shifted) and it's not easy to tell which is the correct one. I'd like to know if the .osm files with suburb data are available somewhere. I have found the postcode files useful but they're missing some of the boundaries where a two suburbs have the same postcode and of course there aren't any relations.

Re: [talk-au] Global warming?
From what I can see it's the same area that was affected before (i.e. most of metro Perth) which was briefly fixed, but is now 'inundated' again. I did look into it briefly but it completely baffled me. However, there were some errors on the Coastline error checker[1] a few days ago (near Scarborough Beach) which seem to be fixed now.

Re: [talk-au] Blue?
Yes, the background throughout most of metro Perth is blue. At higher zoom levels any tiles that don't have blue background will become blue when submitted for rendering (by requesting the tile with /dirty added to the URL). From a brief look the coastline appears to be intact and I can't see any way located on the boundary of the blue background which might be the cause. Arie.

[talk-au] New to mapping in Perth, WA
Hello, I've just discovered osm and would like to introduce myself. I live in Stoneville[1] and work at Edith Cowan University in Joondalup[2] so travel a fair distance every day (by varying routes). It seems that there has been a lot of work getting roads mapped in Perth with a lot of it sourced from Yahoo imagery but there doesn't seem to be much detail or annotation in a lot of areas. I am interested in contributing to the map in Western Australia but I'm uncertain about tagging for a lot of things. For example, I used to live in Greenmount and drove around part of the suburb to survey road names. Most of the roads don't have a source tag and most don't have gps tracks. The odd road has source=Yahoo. So I'm wondering is it worth adding source:name=survey to the roads I've named. And in general is it worth trying to remedy the lack of source information. I've read through some pages on the wiki (in particular: Map Features, the Australian tagging guidelines and the Western Australia specific page - which seems very out of date) and I'm struggling to see a clear path. I've also read quite a few threads on this list and the main talk list and it's apparent that there isn't a consensus about consistent tagging, but I would like to know what other people on this list are doing, particularly in WA.
