Re: [talk-au] new toy found by son
There's only so much gain you can get out of a GPS antenna. Basically the best you can do to cover the whole sky (ie:180 degrees x 360 degrees) is 3dBi (double the power from a perfect isotropic antenna). Certainly you could design an antenna which had a reduced coverage, such as a cone, but it will always be a compromise between satellite count and gain. But saying that most GPS antennas are pretty poor performers, particularly the small patch antennas which are surrounded by metal shielding/PCB traces etc in the unit. For reference, given that the GPS signals are ~1.3GHz (Wiki says they span from 1176.45MHz to 1575MHz) an ideal dipole antenna would be 11.5cm long. A Dipole has a peak gain of 2.7dBi (I think, it's about that). Anyway. I wonder how much use accelerometers would be on a MTB? You experience lots of impulse forces (forces which act over time scales much shorter than the sampling rate of the accelerometer, ie: beyond it's nyquist limit) and so the integration would be seriously inaccurate. Accelerometers would be an excellent solution for mapping tunnels though. Especially since you're only talking about a short-ish time span and you can potentially have 2 accurate calibration points (one at each end of the tunnel). I guess if the accelerometer could be mounted in some form of suspended cage to dampen high frequency noise it would be quite accurate. /ramble -Brent - Original Message - From: John Smith deltafoxtrot...@gmail.com Date: Thursday, October 1, 2009 9:58 pm Subject: Re: [talk-au] new toy found by son To: Liz ed...@billiau.net Cc: talk-au@openstreetmap.org 2009/10/1 Liz ed...@billiau.net: he was hoping that gps+accelerometers+gyros would provide accurate cheap mapping of mtb trails Why not just build/buy a better antenna for the GPS?

Re: [talk-au] I've been trying to fix the highway shields and came across this....
D roads certainly do exist, however at times the signs are covered over/folded up etc. The one I know for certain is a Pacific Highway detour which heads West from Nabiac and goes up to Krambach: http://osm.org/go/uaQzXe_ After that I don't know where it goes. There's a D sign at this intersection: http://osm.org/go/uaQzVoPL but I've not followed it after that. I guess it goes to Gloucester and follows the Buckets Way back to the Pacific Highway ~30km North of Raymond Terrace. The D sign linked to above was only installed after a fatal accident occured on the Pacific Highway at Buladelah which resulted in all traffic being diverted at Nabiac (and a large number of cars passing by our property on Wallanbah Road requiring directions). Prior to that accident ~2 years ago I don't think there was an official detour route, so they may only be temporary and not worth mapping.

Re: [talk-au] navit
Does the ABS have other boundaries which we can use for this? For example Sydney currently would just refer to the Sydney LGA, rather than that area which people would call Greater Sydney. Basically, do they publish boundaries such as greater sydney the newcastle region etc? If they don't then can we get LGA boundaries? That would work for basically smaller than Sydney. For instance the Lismore LGA encompasses Lismore, Goonellabah, Chilcotts Grass...Well, pretty much everything from half-way to Casino up to the Byron Shire. Otherwise could there be a way for us to define regions such as Greater Newcastle or Gympie and surrounds by forming larger multipolygon relations from a set of suburb boundaries manually? I'm just trying to brainstorm a way of achieving what you're describing while still conforming to strict boundary sources as opposed to drawing a boundary around a town by hand.

Re: [talk-au] posters/banners
What I'll probably do is just upload all versions of the banner somewhere and let whoever is paying for the print choose and tweak to their liking. That way all we need to agree upon is the OpenStreetMap name and the magnifying glass icon. In the end it's literally a 5min job to make different versions. For example, I personally believe that the Japanese banner was made for an international audience, why else would it have Japan not only written on it but in Roman characters. So, if we want a banner to be shown in a SoTM presentation then having Australia on it would be appropriate. Otherwise it may be best to have Gathering or Mapping Party or Meeting instead.

Re: [talk-au] posters/banners
Well, what information do you want it to get across? Do we want OSM Australia to become some form of semi-official name for OSM activities/groups in Australia? Or do we just want a sign which says There's an OpenStreetMap mapping party meeting here, this is what you look for to find us in which case the Australia is redundant as we're in Australia already. I certainly think that re-using other OSM logos etc is an excellent idea though as it maintains brand consistency in the online-real world transition. It's probably worth thinking about how this will be seen, too. For instance say you're driving through a town you've never been to while looking for the mapping party meeting place. If you see that poster the text in penstreetmap gets lost very easily in front of the quasi-cammo pattern background. It may work better if the same concept is used with this symbol for the O: http://svn.openstreetmap.org/misc/images/osm_withtext.svg and then penStreetMap next to it, as that way the text is much clearer to read and the form of the magnifying glass is easier to spot while trying to drive. Lastly, whatever gets written on it please try to maintain font consistency :).

Re: [talk-au] Australian Rendering
Hmm, yeah the Wiki entry shows that highway=ford can be a node or a way. Since fords tend to be in isolated places it's rare that somebody would require a zoom level which would differentiate between a node or way ford. From a rendering perspective I'd suggest thick black lines either side of the way. Like a bridge rendering but without the little extensions which stick out at either end.

Re: [talk-au] residential and unclassified in Australia WAS definition of the main highway-tag
Never been further West than Parkes, I'm afraid. I guess this comes down to tagging what exists vs tagging intended use. For instance there are parts of the Pacific Highway which are 2 lanes but are tagged as trunk because they're the Pacific Highway and are therefore the most major road in the area. The situation you're describing of a major thoroughfare which is just a gravel road should probably be tagged as unsealed primary while roads of similar construction which exist so that farmers can get home could come under rural, even if both of them are nothing more than tracks in a coastal dweller's world view.

If you feel like learning how to compile Java code then this page gives some
instructions: http://www.cs.usfca.edu/~parrt/course/601/lectures/java.tools.html
Basically the command javac is the Java compiler. You run it against .java

directory structure of source code and compiled code (.java's and .class's).
Good luck.

[talk-au] Roads that follow ABS suburb boundaries
Greetings Talk-Au, Tonight I tried to enter tertiary roads based on a GPX track I took on a drive from Newcastle to Clarence Town some months back and came to a point where one of the roads follows an ABS suburb boundary. I'm wondering what the best way to handle this is. The GPX track and the ABS boundary agree to within 3m at most points, so it's safe to say that the ABS data accurately traces the center of the road in question. Is it best to draw a 2nd way to represent the way, or some how break up the ABS boundary? So far I've just drawn in the road where the ABS boundary turns away from it. The GPX track in question is here: http://www.openstreetmap.org/user/Biogenesis_/traces/413716 The area of the map in question is here: http://www.openstreetmap.org/?lat=-32.6009lon=151.8143zoom=14layers=B000FTF You'll need to zoom in to see the Data layer to observe my changes before the rendering updates, but the road goes from Clarence Town and runs East to the Buckets way.

Re: [talk-au] Petition to MP
Lets just think about the end goals of getting MPs involved: adding more data to the map. Now basically there seems to be 2 threads of argument about how best to do this: 1) Through mass import of external datasets and 2) through contributions by users. Method 1) is often required for things that can't be easily surveyed, such as administrative borders whereas method 2) tends to yield better results for things open to rapid (ie, static for 1-2 years) changes such as POIs and new housing developments. From that basis one would then ask what is a higher priority for our part of the world. In my opinion completion of street name surveys is probably the highest priority, as once that's done OSM begins to look like a useful tool for people who aren't interested in contributing, eg tourists, small businesses etc. This is not to say that administrative borders aren't useful, but if I was in a foreign country I'm much more interested in navigation, where to eat, where the closest toilet is etc than what suburb I'm in or exactly where the border of a national park is. So anyway, what I'm trying to get to is a consensus on what would be a more efficient use of our time: marketing to the masses or petitioning for government databases. Personally I think that marketing to the masses would yield better results. Ie: organise more mapping parties where newbies are encouraged to attend and are introduced to a friendly, supportive atmosphere. Or get a few small regions finished and get some printed maps into tourist information centers and youth hostels. I dare say that small regions such as the Sydney CBD and Canberra would be excellent pilot projects which could be started right away. By getting lots of free maps out to the people it broadens our readership. Eventually I think it would be really awesome to get an OSM street directory onto bookshop shelves, starting with capital cities (or regional centers, as they're smaller goals) and eventually (in 5-10 years) publishing an OSM touring guide, complete with a Wikipedia-like database of town descriptions, free camping sites etc, kind of like a compeditor to Explore Australia. Anyway, I've seriously rambled on here. I think that both general populace marketing and MP petitioning are needed, but if somebody has some spare time and a choice, what does Talk-Au think they should concentrate on?

Re: [talk-au] Suburb boundaries - getting close
Hi hi, Firstly, having suburb boundaries will allow OSM to be even closer to a UBD replacement :). Anyway, my vote would go for relations. Yes, they're tricky and a lot of people don't understand them but given the current OSM data model they're the right choice. My main argument for relations is that suburb boundaries have a tendency to be defined in terms of roads, creeks etc and including these existing ways will greatly reduce the processing load on OSM. Also, having 3 ways in close proximity (eg, 2 suburb boundaries either side of a road) will get rather ugly when editing. Especially in the flash editor where selecting closely spaced objects can be difficult. Whichever data method is used though this will be a great boost to the OSM dataset, your effort is appreciated. - Original Message - From: Franc Carter franc.car...@gmail.com Date: Monday, February 16, 2009 10:10 pm Subject: [talk-au] Suburb boundaries - getting close To: OSM Australian Talk List talk-au@openstreetmap.org Ok, it seems my conversion script is now producing sane results so it's time to work out what the final output should look like.
