angle, shape, distance, direction projection, coordinate systems

• Gives a reference for size, distance so the user can
• tell what is going on within the map 
• Resolution-High resolution means we're looking at things close-up. Low resolution

– What are some examples that you can think of where space and time may need to be considered within a GIS to conduct an analysis. 

• Computer Cartography 
• Global Positioning System (GPS)
• Geographic Information System (GIS)

• System designed to capture, store, manipulate, analyze, manage, and present all types of geographically referenced data.
• Components: Hardware, software, data, people, methods.
• Power lies in ability of the system itself to overlay multiple layers of both manually and in an automated fashion to assess patterns across the landscape.

Uses a constellation of between 24 and 32 Medium Earth Orbit satellites

 Originally developed by the United States Department of Defense 

Number of satellites in view from a given point on the Earth's surface changes with time

• Ground stations monitor satellite position and monitor error
• Information transmitted back to satellites from ground stations

• Areas
• Angles
• Shape
• Distances
• Directions
