Re: [OSM-talk] turn restriction checker
I have added a check on whether the 'via' is the first/last node in the from and to ways On Sun, Sep 14, 2008 at 8:12 AM, Nic Roets [EMAIL PROTECTED] wrote: Would be great if it could also check this: * a way may not be in any from or to role if it goes *through* the junction (because in that case the information would be incomplete - you would need to know which part of the way is meant!). Just to clarify : For example A ends in a T junction where it meets B. 'to' is B and goes through so it may be unclear if the restriction applies to a left turn or a right turn into B. (Traveling forward / backwards in B). Hmm, I've been slow - I hadn't full appreciated the scope of the problem ;-( Splitting every way that is part of a turn restriction is going to lead quite a few more ways. Although I'm not sure this is a restriction problem, similar things happen with classification changes or bike routes etc Gosmore currently requires the 'restriction' tag because it uses it to distinguish between the two. (And it ignores anything with half, left_right and right_left) Specifically it measures the angles between the segments and considers turns less than 45 degrees to be straight ons and turns more than 135 degrees to be u turns. So there have been at least one case in Australia were it was mapped as no_right_turn while gosmore considered it a u turn. Of the 3 solutions (no_u_turn, only_straight_on and adding a node to give the junction a T shape), the mapper chose the latter. Ahh, I wonder if this is what is causing some of the weirdness I am seeing with route debugging. Can you send me a permalink to the case in Australia I can't see that I will have time to implement anything else before 2009. So I recommend mappers to take the 30 seconds and add the restriction tag and perhaps an extra node. (Just like I recommend always add bicycle=yes/no to trunk roads). If both roads goes through, Relation:restriction simply does not have enough info. (Relation:xrestriction will have enough info, but is not supported or used). So then you have to split at least one of the ways. I should just point out that the newbies here in Pretoria have blindly recombined ways. In the first case the one way had layer=1 and the other didn't have layer set, so the recombine did not result in a conflict resolution dialog. This may well happen in cases where ways were split to make relation:restriction unambiguous. O.T. : In the other case(s) the newbie set the layer and name of the combined way to 1; 2 and Old Pretoria Road; Old Pretoria Road respectively. Nic has said that he uses the restriction=... tag to clarify these. I don't like that idea but if it is used widely then my above rule would have to be lifted for relations with a restriction... defined. There are only 500 odd restrictions. So editing them all should not take more than a few hours. P.S. : I have a very simple proposal for encoding restrictions that never requires splitting ways, and unlike xrestriction it will keep on working if the someone adds an extra node in the final segment.The only drawback is that users will find it difficult. So the best time to adopt it will be when one of the editors gets a restriction editor function.

Re: [talk-au] should we migrate to osm forum
I think flexibility is the core thing needed from whatever is used for mass communication. Some people find email better, some forms and some rss.

Yes, having an australian section on the forum would of course be useful, and it seems to be that moving to forums would probably be the long term trend in this kind of thing.

Re: [OSM-talk] Using Osmarender to hilight Relation/Routes?
Hi Frederick, did you manage to put something together that renders turn restrictions ? I'm interested in anything you have that does that. cheers On Fri, May 16, 2008 at 6:24 PM, Frederik Ramm [EMAIL PROTECTED] wrote: Hi, Sort of like the previously feature image: http://wiki.openstreetmap.org/index.php/Image:Cyclingnodes.jpg I spent a while poking around the Wiki and trying to understand the XSL source (not my forte), but am still none the wiser. Anyone got any hints/clues for me? I was in a similar situation because I wanted to display turn restriction relations on the map; not properly understanding XSL made me then implement Osmarender in Perl (the orp directory in SVN). It more or less does everything exactly the same as Osmarender does, just without XSL. I haven't got round to do it yet but putting in some code/rules there for rendering relations should not be too difficult. (For those with XSLT knowledge it should not be too difficult to add the the Osmarender XSL but I didn't want to go there.)

Currently I am not planning to upgrade on the hardware side, but do not hesitate to suggest different makes, models or add-ons, which would suffer less from this urban canyon problem. Kind regards, IvoM IvoM, I think what you may be after is being able to predict date/times when a) there is a good number of satellites in the sky around you so that your GPS device can get as many readings as possible and choose the best, b) the satellites are well distributed over the sky to help the mathematical calculation of the GPS device and so that they are not all blocked by a tall building at the same time. If so, try typing into Google: GPS Satellite predictor I came up with https://stellarsupport.deere.com/stellar/SatellitePredictor?language=encountry=US If I remember, http://sirius.chinalake.navy.mil/satpred/, is a good one, but it is dead when I just checked it. Unfortunately, even that probably won't help that much with urban canyoning - you'll probably have to do several runs and then tie it in with Yahoo imagery if you are lucky enough to have it for your area. One tip, I've got my best results having my GPS device mounted in a bicycle saddle-bag - it provides a much more stable platform than walking. And if you are walking and your device loses satellite connection, put it on a metal surface - a man-hole cover, traffic-signal controllers, even large waste-paper bins. It seems to act as a ground-plane which improves the antenna gain. I have an external antenna, which has a magnet. When I stick it to the frame of the bus or even the toddler's stroller/buggy, reception increases dramatically. Could this be the same effect, or did I simply increase the size of the antenna?
