Geographic Information Systems

GIS (Geographic Information System) • A system of information and analysis with the elements of geographical science. • A system that uses maps and images to analyze and sort the information.

What can we create with a help of GIS? • Topological maps • Historical maps • Hydrological modelling • Cartographic modelling • GPS in cars • Geostatistics Etc.

Which tools can we use to create GIS? • Sextant (gives latitude) • Clock (gives longitude) • Compass • Tables • Maps New technologies: • GPS and laser rangefinder • Depicted hardware (field-map technology) http: //www. flickr. com/photos/library_of_congress/2179864672/

Where do people use GIS? • • • GPS in car for navigation Google maps Any map (electronic or paper) Class projects Geocaching Detection of geolocation in modern applications Genealogy – trace the routes of your ancestors Crime by location in a city Weather and climate Demographics and human interest Districts and neighborhoods

Some examples… • Weather prediction

• Migration map

• Some interesting statistics

William Rankin • GIS can be used to visualize complex or abstract correlations between any type of information with a geographic component. • “Deciding to learn GIS to make a single map would be kind of like saying you want to learn Excel to make one graph”William Rankin, history professor
