OSM on my GPS
The picture says it all, or rather says most of it at least. I’ve bought a microSD memory card for my GPS, and now it can take extra maps on it. And of course, what map would I want on it, other than OpenStreetMap? Dave and I have spent ages cycling round, doing our local area, and now I get to put the results on my GPS and make up for the terrible basemap that comes with it.
For the technical amongst you, I used JOSM to download and save a .osm of the local area, and then converted that into a Garmin .img file using mkgmap. I can then transfer it to the microSD card using a card reader (thereby avoiding the non-opensource cGPSMapper and sendmap, which doesn’t work on linux for my GPS anyway). It’s interesting that the area bounded by Richmond (W), Hammersmith (N), Clapham (E) and Wimbledon (S) takes up 35K, and my 1Gb card cost £25. There plenty of room for more where that came from.
Ant, can I interest you in the .img file?

I’ve got a new toy, and a new hobby. The toy is a Garmin Venture Cx GPS, and the hobby is using it to make maps, as part of the Open Street Map project - free maps under a Creative Commons license. My flatmate Dave has also bought a GPS, and together we’ve been wandering and cycling around Putney, gathering tracklogs to make the map.
On the map above, we lay claim for the bit around Putney only so far- click on the picture to see which bit is ours. We’ve been doing it comprehensively, rather than just riding around randomly, which makes the maps look really good - I’ll post a closeup of Putney sometime. One of the trickiest bits is when someone watches me cycle down an obvious dead-end, all the way to the end, and cycle back up, while Dave takes a photo of the streetsign - the way they look at you makes you feel what we’re doing is illegal! I haven’t (yet) explained to any bystanders what we’re up to, but I don’t think it would help much anyway. It’s just a pity that everyone, everywhere is so hostile to passers by…
As you can see from the map, there’s a way to go yet, so this will probably keep me occupied for a few millennia! Let me know if you want to help out - next up is Richmond Park, Wimbledon Common, and probably around Barnes too.
