Geographic Information Systems (GIS) merge the graphic features of a map with its associated data, and because of this, in-depth analyses of geographic relationships are possible. GIS is often defined by its method of storing data and features in layers, allowing users to overlay various types of information to view simultaneously. Because of the range of capabilities and limitations, the various mapping technologies currently available on the Web can be roughly separated into three categories according to user requirements, technology, and application capabilities in the library: high level, midlevel, and low level. Customized digital mapping is no longer limited solely to GIS users, since the Internet is rapidly becoming a forum for usable and simplified GIS operations. Libraries of all types may find these new technologies useful in reference, and librarians in all fields are encouraged to become acquainted with the appropriate resources applicable to their daily users.
