What is GIS mapping?

Everything you need to know about GIS and how data is used in GIS.

A Geographic Information System (GIS) is software that blends the power of a map with the power of a database to allow people to create, manage and analyse information, particularly information about location.

Mapping data reveals information about locations and populations vital for a range of sectors, across health, education, manufacturing and insurance. GIS means the latest mapping data can be communicated and used most effectively.
