to import/convert (short of writing a converter myself). I'm assuming it's in the ESRI .E00 ancient exchange format. You actually have to go .E00->arc info->shp->osm I'm working on automating a toolchain to spit out .shp files (because those are the most useful to me) and then another bulk importing toolchain from shp->osm->api To get you started though, esri has a program called import71.exe that will convert e00 to arc info coverages I just run it from within a windows virtual machine in linux. There is also http://avce00.maptools.org/avce00/index.html which I will be attempting to use to automate it. To get from arc info coverages to shp files you need gdal [1], and proj.4 [2] and I went the python route so you need the python bindings [3] If you're on windows, Leszek from freegeographytools.com has made a GUI to gdal [4] which I've only used a few times. I suggest not getting FWTools and instead setup everything by hand seperately. Then you can use one of the various python or perl (no ruby scripts?) shp -> osm scripts (or one of the java programs).

My take on the problem with Olympic National Park (where there is pretty good data) is to just import all of the park trails (which I found the National Forest Service has but NPS doesn't) and then as I'm hiking around and working in the park I'll check the trails. From a quick look at the Yahoo! aerial photography the park data appears to be pretty much spot on (barring washouts, avalanches etc) so I'm not foreseeing any problems with a bulk upload. For areas where the USGS maps are better (they are notoriously awful here) you can always use the USGS WMS server to get in preliminary trails. I do definitely like the idea of a bunch of hikers ambling around our national parks with gps units and going to town on OSM, though. The NPS has some GIS data available at... I've just created a NPS Data Sources page on the wiki [a] with blatant plagiarism from the US NFS wiki page [b]. You may want to create a mapping parties section on there. In addition to the NPS Data Store many universities catalog US Govt. GIS data so checking for 'University of ____ GIS "data store"|clearinghouse badlands trails' in google will often turn up some data.
