Re: [talk-au] Rivers that have dams on them
Hi. I would run the main waterway=river way through the lake polygon, like you run it through a riverbank polygon. - Ben Kelley On 12/06/2013 2:32 PM, "Brett Russell" wrote: > > Hi** > > I am now starting work on rivers and streams but would like some guidance > on dealing with rivers that have dams on them.

Re: [talk-au] Alphanumerics in Northern Territory?
Hey Mark, Good question about NT alphas. I might be able to point you the right way. I'm a member of the Aussie Highways Google group… Sam Laybutt over there (admin of the group) also runs a very good website called ozroads.com.au and he has a page dedicated to the NT alphanumerics - http://www.ozroads.com.au/NT/routenumbering/alpha/alphas.htm I'm sure he'd appreciate your updated observations too. Sam's very knowledgeable and seems happy to share info with OSMers. I can ask him on your behalf if we can use that info if you like, or feel free to join the Google group yourself and participate in the discussion over there. For NSW at least it's a great way to monitor exactly when each alpha route gets commissioned - and in many cases we can pinpoint the exact date and put it into the database as a historical reference (I've been using ref:start_date for this purpose).

[talk-au] Rivers that have dams on them
Hi I am now starting work on rivers and streams but would like some guidance on dealing with rivers that have dams on them. A good example is the Forth River in Tasmania. I have started building up the river banks as it can be quite wide using the polygon tagged riverbank and had no issues as yet. But what do I do with hydro lakes? I have read that some OSM mappers do not like the river running through the lake and prefer it to stop and start it at the lake. Must admit that I struggle to know when a river stops and lake starts when working from Bing. Also, water may go a little distance in an underground pipe so you get a gap from the dam wall to the outflow from the power station. I assume we map what we see from Bing? As usual, any guidance would be appreciated to improve my mapping quality. I used OSM on a nine day Overland Track Wall and found it very good with the Garmins that I was using. Used the routable maps and found they were about a one kilometre in ten understated on distance due to fewer nodes recorded in OSM compared to the distance tracked by the GPSs. Still very impressive compared to the expensive and poor quality Garmin maps. Need to work with someone to get OSM bushwalking maps going as walking tracks, mountains and huts need to be zoomed in a long way to see thus you get “lost” in the trees finding them. Also the search feature on the Garmin can be rather “broken”, by that items do not appear in the all POI lists but can be found in sub lists. Bit more work needed by my to refine the tracks and the features but gradually working my way south to north refining the track. Mud Map 2 looks promising but sadly it does not render lakes and mountains being optimised for 4WD tracks. It is better suited to the 4WD users than bushwalkers at the moment but I do hope that they continue its development to cover bushwalkers. It would be great to combine Contour Australia 5M with OSM data into one img file rather than having both OSM and Contour Australia 5M maps enabled. Especially useful for Garmin Basecamp on the computer as you either have OSM or Contours Australia 5 showing. Also for drawing in rivers and streams it would be good in JOSM to have Contours Australia as a data layer so I can deal with rivers and streams that run under forest cover. As usual again any help greatly appeciated. Cheers Brett ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au
[talk-au] Alphanumerics in Northern Territory?
I'm just about to start my OSM edits from my recent Central Australian trip. I noticed a few signs on the Stuart Highway between Alice Springs airport and Alice Springs that had the route number "A87" (and a brief glimpse of one that looked like "A1"!), yet all the other route numbers I saw on the Stuart Highway (between the Lasseter Highway at Erldunda and Churchills Head north of Tennant Creek) were national highway 87. Does anyone know if these are mistakes, or if this route is going to be converted to alphanumeric soon? (i.e. is it too soon to change the route numbers?)

[talk-au] National Library of Australia - Mapping Exhibition
Hi, The National Library of Australia is planning an exhibition on mapping starting in November this year till March 2014 and wanted to know if we had any ideas for activities that OpenStreetMap might want to run as part of this or associated with it. There are some nice visualisations that could be used, e.g. http://osmlab.github.io/show-me-the-way/ Show me the way which shows OSM edits in real time. Is there interest for a workshop for beginners and hands on mapping party in Canberra at some point? Any suggestions, particular from local mappers?
