Over 50,000 free maps

Free_the_maps Late this past summer, Jared Benedict posted a ransom note for maps. But he wasn't holding them hostage; on the contrary, his goal was map liberation. And now he has succeeded. The Libre Map Project  has posted over 50,000 free USGS topo maps.

I've been following this for awhile, and last weekend, all the maps  were finally made available. These are 1:24,000 scale, 7.5' digital raster graphic (DRG) quadrangles. I've posted before about free USGS topographic quad maps, and about OziExplorer, my favorite mapping software that allows you to use DRG's with (but not on) your GPS. Here is a good resource on importing DRG's into OziExplorer.

GPS for cyclists Last updated February 24, 2009 Whether you are a road biker or a mountain biker, there'€™s a GPS that will work well for you, and it can mount right on your handlebars. Either type of cyclist will have special needs, so let'€™s take a look at your options: GPS for road bikers GPS Cyclometers The Garmin Edge series is comprised of cyclometer-type GPS receivers. All of them have high-sensitivity chipsets for superior satellite reception in urban canyons and under canopy. While they are excellent cyclometers, they aren'€™t all that great as navigation devices (more on navigation options below). If you are primarily wanting to track your performance though, the Edge series is an excellent choice. The newest models are the Garmin Edge 605 and Edge 705, which add color screens and mapping capability (maps purchased separately) to the features found on previous models. The 705 adds a heart rate monitor, barometric altimeter and the ability to share data wirelessly with another Edge 705. The 705 is also compatible with an optional cadence sensor and power meter. For a detailed look at the new Edge models, be sure to check out my hands-on review of the Edge 605. The first-generation Garmin...
