We've just taken the wraps off our newest feature, our Ski Map North America
displaying every ski area in the U.S. and Canada. You can select between different types of maps, including a Google street map, satellite photos, or a hybrid of both, plus USGS topographic maps and the Daily Terra and Daily Aqua maps, which display yesterday's Landsat satellite images, updated daily. It features the ability to pan and zoom.
Known issues include slow loading time -- after all, there are literlly thousands of waypoints to plot on the initial map showing the whole continent -- and a few ski areas whose location is a little bit off, although by and large the vast majority are spot on.
