World Wide Web (WWW) is the most recent new medium to present and disseminate
geospatial data. In this process the map plays a key role, and has multiple
functions. Maps can play the traditional role of providing insight into
geospatial patterns and relations. Under these circumstances maps are
used as they would in e.g. an atlas or newspaper to present the structure
of a city or the location of the latest earthquakes. However, because
of the nature of the WWW the map can also function as an interface or
index to additional information. Geographic locations on the map can be
linked to for instance photographs, text, sound or other maps (multimedia).
Maps can also be used to preview geospatial data products to be acquired,
when it comes to disseminating the data.
