MapView is the only solution to view large maps on your Palm handheld with high speed and in native resolution. Using bundled MapMaker application you can create on your desktop (Windows only) a specially formatted map file from any of your images and then view them on your Palm with MapView. No matter what the original image size is, the map file will open almost instantly and you can zoom it in to see all the details of the original image. Of course, the files displayed by the MapView do not have to be maps only - it is suitable to view any high resolution image. To make maps viewing even more useful MapView supports GPS Bluetooth devices and allows mapping coordinates received from GPS device to the currently displayed map file so you can view your current position on the map. This feature is especially useful when maps for some areas are not available for your bundled GPS software - you can simply scan the paper map you have, convert it using MapMaker software on your desktop, copy to the Palm, bind the map to the GPS coordinates and use it to get your current location.
