At this point in time there is no way possible that everyone will actually be getting 2m or better of accuracy all the time unless they have better than currently available consumer grade kit.

[talk-au] How to map out streets the most efficently
In my up an coming trip to SE QLD, I'm probably going to go through a number of largish, relatively speaking, regional towns that aren't mapped out except for a handful of streets and most if not all were from landsat imagery. Now does anyone have suggestions on how to basically drive the entire town the most efficiently with the minimal amount of overlap, or how does one plan such a feat. Towns I'm hoping to map, given enough time, include: Moree: http://www.openstreetmap.org/?lat=-29.46771lon=149.83826zoom=14 http://maps.google.com.au/maps?q=moreez=14 Goondiwindi: http://www.openstreetmap.org/?lat=-28.5381lon=150.3039zoom=14 http://maps.google.com.au/maps?q=goondiwindiz=14 Millmerran: http://www.openstreetmap.org/?lat=-27.8779lon=151.2712zoom=14 http://maps.google.com.au/maps?q=millmerranz=14 Pittsworth (which wasn't even marked till this evening at all): http://www.openstreetmap.org/?lat=-27.71lon=151.6359zoom=14 http://maps.google.com.au/maps?q=pittsworthz=14 Oakey: http://www.openstreetmap.org/?lat=-27.43068lon=151.71903zoom=14 http://maps.google.com.au/maps?q=oakeyz=14 Going the most direct way through these towns will be over 700km, normally the trip is closer to about 600km, and that figure doesn't include the extra milage doing streets. I have a bit of a time constraint as I'd prefer not to be driving after dark and bumping heads with the odd roo :) When I mapped out Inverell I was a little less prepared/experienced but even so it still took about 3hrs of driving to nail all the streets, which if I do even half the time in most towns I'm looking at a pretty hefty amount of time in the day just mapping. Is there any cheats people could suggest to speed up the process, even if the data collected isn't perfect but would allow for any blank spots to be extrapolated to fill in the rest of the picture? If I set off at first light, I'll have about 10 hours of daylight and need to travel 700km, although the closer I am to my destination by night fall the smaller the animal I'm likely to hit. Just to give you an idea, out round Goondiwindi I've seen 6' roos. Unfortunately none of the roads I'm taking are signed at anything higher than 100km/hr, so I can't make up time that way, and yes there is highway patrols along at least half the roads, if not most. If there is a remote chance of extra time the other towns I'm going through are Nanango, Goomeri and Kilkivan, all of which have pretty poor mapping as well, but are smaller than the towns I've out lined above.

You can also get into datum issues, OSM uses WGS84, which differs from DGA94 by about 1m at present (my best guess, still trying to find a surveyor to confirm), however as time goes on this increases by about 7cm per year due to the Australian continental drift. However that isn't the biggest source of error, most consumer grade GPSr units are only qualified accurate to about 10m, although this can be minimised by doing an average of location data over a 24hr period, although this is fairly time consuming obviously. Until we have dual frequency receivers to eliminate sources of error with atmospheric conditions 10m accuracy should be acceptable for most purposes, unless you are a surveyor of course. I've come to the realisation that every road (and everything that was placed in reference to the roads) in the suburb where I live is out by about 8-10m. Much of Brisbane's road system seems to have been traced off the Yahoo imagery, apparently without aligning it to fixed points before hand. 8-10m isn't that much of an error to be honest. There really isn't any such thing as perfect data if you are using consumer grade equipment of any sort, things will improve over the next 10 to 20 years with other constellations of GPS like sats starting to broadcast, but until then 10m is as good as it gets for the most part for most things unless you spend a lot of time getting very very accurate positioning. When I've been going around recently, I started noticing that POIs on the north-east corner of an intersection looked like they were on the SW corner. Obviously the best solution is to go out and capture all the roads with my GPS, but I'm wondering what to do in the mean time. That can happen at diff zoom levels because of the x,y offset position that they are plotted from also. If I leave the roads where they are, the data I'm putting in will look wrong as it's not consistent with where the roads have been placed. Moving just the intersection will make the road appear to bend in places it doesn't, and would be a fairly arbitrary thing. I could go around and move every road in the suburb the same distance, but that'd be a fair bit of work, and I'd probably screw something up. IMHO if you have a better source of information it should be used, and over time errors should be corrected by others till things do look right, since seeing mistakes motivates people to fix them and in some cases to go on and do other things too. ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au

[talk-au] GPS Shoes For Alzheimer's Patients
A shoe-maker, Aetrex Worldwide, and GTX Corp, a company that makes miniaturized Global Positioning Satellite tracking and location-transmitting devices, are teaming up to make shoes for people suffering from Alzheimer's Disease. The technology will provide the location of the individual wearing the shoes within 9m (30 feet), anywhere on the planet. Sixty per cent of individuals afflicted with Alzheimer's Disease will be involved in a 'critical wandering incident' at least once during the progression of the disease — many more than once, said Andrew Carle, an assistant professor at George Mason University who served as an advisor on the project. Not only will this technology allow a caretaker to find a loved one with a click of a mouse, but the shoes are more humanizing than a bell hung around the neck. http://www.news.com.au/technology/story/0,28348,25596210-5014239,00.html Maybe a GPS bouy isn't far fetched after all. ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au

However retreiving the bouy, especially in western rivers would be more time consuming than taking a kayak and doing it manually yourself since it would likely get caught up on branches/debris, snagged in fences across water ways, stolen/vandalised etc. Not to mention when the rivers flaten out they take forever to get anywhere. ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au
