2. Objectives ► Understand the basic premises of GIS  Cartography / Map Making  Geographic Analysis ► By Learning the basics of  GIS software and databases  Different geographic datasets  Basic map creation

3. Objectives ► What is GIS? ► Examples of GIS ► Issues and problems/obstacles to using GIS ► GIS software and Data ► Hands-on

4. 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 postal codes Province Province City City longitude and latitude longitude and latitude lot numbers lot numbers concession numbers concession numbers census tract census tract wards wards etc. etc.
