OSM on my GPS

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?

    Hi Andy,
    Is there a set of instructions somewhere for Mac OSX [Free BSD] users to get OSM maps onto a Garmin Oregon 400?
