What Are Digital Maps?

Digital maps are computer-based representations of earth phenomena. These maps may have been paper-based prior to being scanned or digitized into their digital forms, or they might have been generated digitally using computer software. Digital maps are stand-alone products that can be provided in a number of file formats, such as PDF, JPEG, or GeoTIFF. Map viewers are platforms on the World Wide Web that are interactive, allowing you to move around and zoom in or out to view the phenomena on the viewer. Some map viewers are solely interactive, while others also allow you to download digital maps (either pre-defined or user-defined).
