Giới Thiệu · MacTopos The USA at 250K
MacTopos The USA at 250K are USGS digital raster topo maps that cover the entire US at approximately 100 miles by 70 miles per map. They are ideal for seeing the overall topography of a large region. They do not have the close-up detail of the 24K scale maps contained in our MacTopos individual states DVDs.One DVD contains the entire United States in the 250K map scale. New technology allows the same sharp detailed images as the original Digital Raster Graphics maps from the United States Geological Survey, except they are compressed to save space without losing resolution. Install any or all of these 631 maps on your Mac using less room on your hard drive, or use the maps directly from this one DVD with no need to switch or store additional disks while traveling. And one DVD saves money in production costs - this savings is passed on to you. Use MacTopos to simplify your map life!
