 The
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.The purpose
of this book is to provide information on the new opportunities and challenges
offered by the WWW for cartography and related geosciences. It describes
the developments, changes and prospects of the mapping discipline in the
framework of the WWW. In this framework a web map classification scheme
is proposed. It distinguishes between static and dynamic web maps. Each
of these categories is further subdivided into view-only and interactive
maps. The most common map found on the WWW is the static view-only map.
Often the sources for these web maps are original cartographic products,
which are scanned and put as bitmaps on the WWW. Static maps can also
be interactive. These are the so-called 'clickable' maps. The map can
function as an interface to other data. Alternatively it could allow the
user to define the contents of the web map by switching layers off or
on. The WWW has several options to display dynamic processes via animations.
The so-called animated GIF can be seen as the view-only version of the
dynamic maps. Interactive dynamics can be created by Java, JavaScript
or via virtual environments in VRML or QuicktimeVR. |
