What is GIS?

• A GIS is a computer application with the capacity
  to assemble, store, manipulate, analyze, and
  display geographically referenced information
  (geospatial data)

5
What are Geospatial data?

• Data must fit with other data
• Geospatial data are georeferenced data
• (ie. they have a geographic field)
• postal codes
• Province
• City
• longitude and latitude
• lot numbers
• concession numbers
• census tract
• wards
• etc.
