Yahoo's online maps combine many small, highly detailed images into larger views with interactive feature like the ability to zoom and rotate the image. Allallsoft's Yahoo Satellite Maps Downloader is a small but capable tool that you can use to select and download Yahoo satellite images and put them together into highly accurate, highly detailed interactive maps. Multithread technology downloads large geographical information files quickly, and it saves images to your hard drive or other destination for immediate use or to be used later to create other maps. It only downloads Yahoo satellite map images. For regular Yahoo maps or other mapping sites, you'll need one of Allallsoft's related tools.

Yahoo Satellite Maps Downloader has an attractive and efficient interface that keeps things simple. You need to understand map coordinates to use it, but the program makes it easy, and there's a Help file if you need it. To create custom maps, you define the boundaries of the region, select Zoom and Thread Count levels, and press Download. Yahoo Satellite Maps Downloader quickly retrieves and assembles the parts into an interactive satellite map view. Maps on Yahoo are for personal purposes only, so if you need commercial images, a geographical information system (GIS) package or image service may be a better choice. For nearly every other use, though, it's a great choice.

Yahoo Satellite Maps Downloader is free to try, but the Zoom function is limited to a maximum level of 6. It's certified for versions of Windows up to Vista.
