Geographic data is about much more than electronic
pictures of
maps.
The geographic data that describes our world allows for
city planning,
flood
prediction and relief, emergency service routing, environmental
assessments, wind pattern monitoring and many other
applications.
Geographic data is processed with
Geographic information system
(GIS) software which can, as one aspect of its functioning, produce
maps.
In the
United
States
, geographic data collected by central government is
made available free of copyright for no more than the cost of
distribution. The
United States Census Bureau's
TIGER Mapsurfer provides a web
service and also offers data free for download. TIGER allows you to
build a
geocoding facility with which to
spatially locate addresses. Given the ability to geocode street
addresses and other features, one can create a lot of interesting
spatial analysis,
location-based
service,
political
campaigning apps and localised
search services.
In the
EU there is a
European Union directive (INSPIRE
directive) to establish shared
standards between the different countries,
accompanied by web viewing of rendered map data, and an as yet
unspecified license framework for geographic data.
