What is GIS?
2
Geography and Technology Geography affects us in many ways: Our natural environment Our human environment Geography has become a high tech discipline: Earth Observation Global Positioning Systems (GPS) Geographic Information Systems (GIS)
3
What is a GIS? GIS= Geographic Information System A method of organizing data Geographic Data (Maps) Descriptive Data (Databases) Images A method of distributing data A method of analyzing data A method of visualizing data
4
How does a GIS Work? In a GIS, different types of information are represented as separate map layers Each layer is linked to descriptive information Layers are combined to make a map
5
Describing Our World We can describe any element of our world in two ways: Attribute Information: >What is it? Location Information: >Where is it? Building Type: Office Height: 100 ft. Condition: Good
6
Linking Datasets GIS software links the location data and the attribute data:
7
Analysis GIS can analyze data in many ways GIS software can answer our questions about the world: Spatial Questions >What provinces border Saskatchewan? Attribute Questions >What provinces have more than 1.5 million people?

Summary GIS is about using data to describe our world in two ways: Location Data - Where is it? Attribute Data - What is it? GIS software maintains a link between layers of location and attribute data With the link, we can ask questions about our world… GIS is a multi-disciplinary tool in education GIS is used in real world applications across various industries
