An international cycling map created from OSM data is available, provided by Andy Allan. The map rendering is still being improved, the data are updated every few days. It shows National Cycle Network cycle routes, other regional and local routes, and other cycling-specific features, such as:
  • dedicated cycle tracks and lanes
  • bicycle parking
  • contours and hill colouring
  • bike shops
  • proposed bike routes (or numbering protocols), contrasted with the Lonvia map, below, which does not show proposed routes, but actual routes only

Lonvia's Cycling Map by Sarah Hoffman is an overlay which shows marked cycle routes around the world. Updated daily, it renders actual routes without the state=proposed tag. Therefore no proposed routes (or numbering protocols) are displayed.

I don't give a flying monkey's for tag voting, automatic changebots, endless discussions, categories, or any of that crap, but prefer to get on and actually do stuff.


My priority list

Here's a list of things that I think are high priority for the project. I'll get round to them all eventually unless other people beat me to it, but that could take a while. If you see anything that's on this list and you'd like to see it happen, let me know if you can help. If you want me to stop working on other things and concentrate on this stuff - and you've got funds - get in touch!

Garmin eTrex Venture Cx

custom mkgmap highlighting cycle routes

I've got a Venture Cx, that I bought almost exclusively to use with OSM. So I'm glad it works! Here's some tips if you've got a similar model:

Linux

It works fine with linux, once you get it going. It's got a mini-usb connector on it, but doesn't come with a cable - don't worry, any old usb -> mini-usb cable will work, so you can ignore all the GPS Serial to USB stuff. For Kubuntu 6.06 Dapper (would be the same for Ubuntu) I make the changes from this page in the Fedora Core 5 section, but I'm not sure if that helped. What definitely did was installing a newer version of gpsbabel - Dapper comes with 1.2.7-1, but that doesn't support the Venture Cx. I downloaded and compiled 1.3.1 - install libusb-dev (using Adept etc) first, otherwise it won't add USB support, which is needed! It looks like Edgy will also ship with 1.2.7-1, which is a pity.

I use the "gpstransfer" script from How to get data from a Geko 201 to get the data off the GPS when it's plugged in.

Settings

I've found that setting the tracklog to 4 seconds on foot and 1 second on a bike is perfect for the comprehensive walking-up-and-down streets that I like doing. Just don't "save" the tracklogs! As I found out after a few days, thanks to this page, the unit heavily compresses the data when it saves - it strips out all the timestamps from each point, and tries to strip out as many points as it can from straight line areas. I had spent a day or two thinking the GPS reception was really shit! And OSM won't accept tracklogs without timestamps, so it ruined one afternoon's work - thankfully, JOSM didn't mind, so we got the streets sorted anyway.

Also, the gpstransfer script pulls all the tracklog data into the output file (is there a way to change this?), so if you keep any old tracklogs saved, when you pull the fresh ones you'll get the old crud too.

Maps

I use mkgmap to get OSM maps onto the GPS, since the basemap that comes with it is so rubbish! It really rocks, and it's a little bitty cheaper (and much more cool) than buying commercial maps. A 1Gb microSD card only costs 25 quid, and with about 9sq km only taking up 35Kb, there's plenty of room for more maps!

Need a map was a HUGE SUCCESS.
It's hard to overstate my satisfaction.
