Re: [Talk-us] Garmin OSM map for whole US
A bit of a sweeping generalization there Paul :). There are lots of people who travel frequently on business all over the US - I have been one of them, though less so these days. Often trips might be at short notice and take in multiple states. It's also very common for people to take road trips across multiple states. Given the somewhat clunky nature of getting downloads and transferring them to GPS units, combined with the ridiculously cheap cost of storage cards these days, I think that a US extract would be very useful to a lot of potential users of US OSM data.

I'm not sure it's a common need, considering that most US states are larger than most countries in terms of geography, with most of the population more or less stranded within 100mi of home largely due to high fuel prices, complete lack of railroad transport and abysmal air transport connections. ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us -- Peter Batty - President, Spatial Networking W: +1 303 339 0957 M: +1 720 346 3954 Blog: http://geothought.blogspot.com ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
[Talk-us] Garmin OSM map for whole US
For those of you that don't know, Cloudmade has some really cool ready-made maps available for download. I know they work on Garmin devices, but there are probably some others. http://downloads.cloudmade.com/north_america/united_states The problem is that they're made one state at a time. I'm lazy, so I buy large cards for my GPSes and load the whole country on them so I don't ever have to reload maps. But, with the Cloudmade maps, I have to only load a single state at a time. If I want another state, I have to take the card out (or plug the GPS in) and move another state's gmapsupp.img file in. Well, mkgmap has come to the rescue: http://www.mkgmap.org.uk/index.html It allows you to combine several gmapsupp.img files. I've downloaded all of the US states (plus a few territories), and fed them through mkgmap. The result is a single file you can put on your Garmin GPS for the whole country. I've also stuck the bash script in here so you can see how I did it: http://dev.openstreetmap.org/~daveh/garmin/ Just download, bunzip2, rename USA.$DATE.gmapsupp.img to plain 'gmapsupp.img' and move it over to your device. There are a couple of little issues with the way roads get drawn. Some little residential roads get drawn in bold red (is this from the OSM.err stuff?). So, if you know the Cloudmade people who are working on this, I'd like to get in touch with them to make a few minor tweaks. I'd also like to get this off of the dev server and put somewhere a bit better for downloading such a big file. Can anybody at Cloudmade want to share the scripts/programs that are creating these files? Does anybody else have some nice USA extracts that could be used for making garmin maps? -- Dave ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us

Re: [Talk-us] Garmin OSM map for whole US
you can run osmosis on the planet with a US boundary polygon. If you don't mind some overlaps with Canada and Mexico it is easier to clip a rectangle. this is what I use to get all of washington, oregon, california in one extract. bzcat planet | osmosis --rx pipe --bb left=-126 right=-113 bottom=32 top=49.5 clipIncompleteEntities=true --wx - | gzip -c clipped planet Osmosis can compress/decompress the files but runtime on multicore machines is better this way. Also bzip is terrible slow and I prefer gzip for compression.
