[Hampshire] Unpicking gps data
Hi I have no idea where to start, but I'd like to display all of the roads in the UK that are deristricted, but not motorways. The simple reason is that I am a motorcyclist, and am frustrated with picking nice bendy roads on a map to find they are all 30 or 40mph. There are a few 'best roads' sites, but they tend to be for head down, ass-in-the-air performance bikes that seem to like going at 140mph along straight roads. So, the idea is to suck the data out of a gps device (not that I have one), and then ask it stuff. I assume that gps data is a database with name, class, start point, end point, speed grading, speed limit etc. Can anyone help please (suggesting I get a push-bike and stop polluting the planet is not necessarily classed as help, in case you were tempted)? Thanks Ed -- Please post to: Hampshire@mailman.lug.org.uk Web Interface: https://mailman.lug.org.uk/mailman/listinfo/hampshire LUG URL: http://www.hantslug.org.uk --

I can't help with the GPS data, but a fun ride can be found on the A4, the Old Bath road, west of Marlbrough. It's an old three lane, now marked as 2 lanes. Low traffic during the day. Hungerford to Marlbrough also can be fun, but not quite as quite or a sensuous a set of curves IMOSHO.

Thanks Ed This sounds like an ideal problem for the http://openstreetmap.org data. With a bit of work, a map could be created with the roads you want highlighted. There are even sites that let you play with the map style on-line, but you will have to search for them, as I don't have a reference to hand. -- Philip Stubbs -- Please post to: Hampshire@mailman.lug.org.uk Web Interface: https://mailman.lug.org.uk/mailman/listinfo/hampshire LUG URL: http://www.hantslug.org.uk --

Ed, OpenPilot will do bits of this for you. The steps go something like: 1) Obtain a hand-held GPS. 2) Ride the route to get a GPS track of where you've been. 3) Save it as a track file on the GPS. 4) Upload said file to Computer. 5) Use a tool that handles GPS data to load the track. and manipulate it as you wish. In step 5, the GPS data is usually stored as just a series of NMEA0183 (possibly proprietry) sentences. These are pretty easy to read, and OpenPilot has code to do this for Magellan GPS tracks. Once you've read the data you'll have a time and location. You can then plot this on a map, reference it against OpenStreetmap etc. etc. OpenPilot does a fair amount of GPS handling in the Map widget.

Re: [Hampshire] Unpicking gps data
A while ago I was creating a mapserver for a sister company, we shelved the project but I recall GIS data that had what you need. It's often freely available and road data files tend to have speed limits and road classifications. While I don't remember exactly where I go the data I had from, but it looks like there is free road data here: http://data.geocomm.com/catalog/UK/group103.html I don't know if that file contains road specs or limits, but it's definitely out there.

You seem to be confused :) To clarify things, GPS is purely a system to work out your current location. GPS navigation devices us a GPS to plot your location and route on its own internal map data. Note that this map data is normally in a proprietory format and VERY expensive to licence to use. As someone has already mentioned, there is the OpenStreetmap project to recreate the map data with an open licence that will include the information you want. Once you've had a good look around the site, you can extract suitable data using the OSMXAPI. I hope this helps :) -- Dee Earley (Creator of Whiteley on OSM :) -- Please post to: Hampshire@mailman.lug.org.uk Web Interface: https://mailman.lug.org.uk/mailman/listinfo/hampshire LUG URL: http://www.hantslug.org.uk --
