[talk-au] Sturt Highway Virtual Mapping Party 09/10
Waikerie is looking good. I think that the mapping party has significantly improved the Riverland area. Ahh - Manangatang - one of my favourite town names. Other areas that really need some kick starting are the SE of both S.A and VIC. Also next christmas I must try to map Mt Barker. If it may become S.A's second city, we really need it mapped completely. ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au

[talk-au] Sturt Highway Virtual Mapping Party 09/10
My bits of this event are now edited in. I added some roads to Euston, mapped Paringa and then nearly finished Renmark. I eventually got sick of driving all those numerous dirt laneways (all alike) and left them till next time. If we do this again next year, I could finish Renmark, map Renmark North and South and Maybe Lyrup. During the holiday period, Verdun, Balhannah, Oakbank and Hahndorf all fell to the mighty Mio C230. I remember that about a year ago someone requested that Naracoorte be mapped. Well I thought that this wasn't too much of a detour so I mapped it on the way back to Canberra. I've missed a few streets so hopefully someone will add these, otherwise, I'll get them next year.

John H Missed quite a few streets in Waikerie as we managed to drive inefficiently in a circle, but when i downloaded all the gpx files from the server there was good additional information there. We did some more streets in Lameroo and a few more in Manangatang but haven't uploaded that work yet ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au

I A little redundancy can save a ton of CPU cycles calculating this every time, this is why tiles get cached rather than drawn on the fly for each request :) Since we're consolidating all the highway information 1 or 2 extra tags per relation will be less data in total than we started with. That said I finally figured out a suitable SQL query against pgsql/postgis to calculate it. select name from planet_osm_polygon where ST_Contains(way, ST_SetSRID(ST_Point(149.8422 * 20037508.34 / 180, ln(tan(((90 + -29.4642) * pi()) / 360)) / (pi() / 180) * 20037508.34 / 180), 900913)) That's for the point -29.4642, 149.8422, but you can use the same ST_Contains() function to compare relations with polygons so it's relatively straight forward to find out what state/country a line falls in. Once I convert the MySQL queries across to PostGIS queries the lookup times on searches should be less as a result. ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au

I thought the network tag was for removing the letter prefix from the number, but are we now doing network=A, ref=A1? Isn't this just the same as before but with an extra tag? The problem here is we have 2 distinct systems, things like NH, NR, MR which aren't part of the reference, and then the alphanumeric system MABC which is part of the reference. So the best I could think of in the case of MABC was to include it in both the ref and the network, I think in the UK they only have MABC so they don't have to consider anything else. I think this is why I am concerned about adding the addr: tags to the ref relations, is it not redundant data given that we have suburb boundaries, we know with reasonable certainty that a node is in what suburb/state/country? I see changes to the cycle route tagging guide says to potentially add all suburb/state/country tags. It's like adding is_in tags to all nodes/ways even though we have suburb boundaries (thanks again Franc!!). Is it some limitation of the mapnik styles that caused the US guys to create the similar tagging scheme? Ideally it could be solved with code instead of adding to the burden of tagging. I have no idea if they have boundaries in place or not, so it might have caused this to exist, then again the same could be said for most addr:* tags. Also looking at the the text for the Route section of the Au tag guide page, I think it is too verbose mixes guidelines with reasoning thoughts. Given it's a wiki, I might work on wording and make some changes (kind of similar to the OpenSource mantra of stop whinging, show me some code). The gist of it is leave: * mention old new shield system * tagging example * Highway Refs (but name it something like Network Refs or Sign Shield Refs) Go for it. Move Minor Roads sentence to the Naming Streets sections (since that is what it is). Remove the distinction between Major Minor Highways tagging, to something simple like: If a named route a numbered route follow the same ways, combine into a single relation. If they finish at different spots or take different paths, create a separate relation for the named numbered route. Example of a combined: name= Thingamajig Highway network=C ref=123 route=road type=route I've not done much with B C routes, but there is a number of mismatched A routes that chop and change names, A3 in QLD for example starts at the junction of New England and Cunningham Highways north of Warwick, then that joins the D'Agular Highway for a bit and then follows the Burnett Highway all the way to Rockhampton. The D'Agular Highway goes from S85 to NR17 to A3 and I'm not sure what happens after it stops being the A3 it wasn't tagged. On the other hand NR38 is only the Gwydir highway except for small sections that it shares with the Newell and New England Highways. I imagine some/most BC routes may be a single segment effectively, except if there is bridges and it might be just as easy to tag the way as it would to create and tag a relation. ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au

Re: [talk-au] Sturt highway
I've been marking all members in a relation as a role member not forward/backward as we don't have official designations such as east/west/north/south like they do on US interstates. I'm not saying I'm right but it is less work :) You have ref=NHA20 for NHA20 in SA, but I'm not sure what to do here, because the road is tagged as A20 in a NH shield, just so South Australia can be different I guess :) I think I'd just tag it as ref=20, network=A and then we can add a rule to show NH shields for these routes for addr:state=South Australia ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au
