What is GIS?

A geographic Information System is a collection of tools to build, maintain, and use electronic maps and associated databases.

What does GIS DO?

it Locates:

  • Assets, (power stations, pipes, oils fields,,,,)
  • Areas, (land use)
  • Incidents, (crime and health statistics)
  • Characteristics, (disease mortality rates)

GIS allows questions to be asked from the map side or from the database side. Questions can be asked by either side because the map graphics and database are linked via a unique number.  It allows questions to be framed geographically.

GIS is a way of organizing database records by tying them to
geographically synchronized slices of the world so that “where”
questions can be answered.
