I bet you have a stack of roadmaps in your car that you use when you go on a road trip. Just kidding. You open up Google Maps on your phone . What are the geospatial technologies we have access to? 

  • Global Positioning System (GPS): used for navigation, provides your precise location in relation to surrounding areas and your destination

  • Remote sensing: satellites orbit Earth and send the data back to Earth

  • Geographic Information System (GIS): a computer system that stores information about locations in “layers”


A layer represents a different piece of human or environmental information (such as cities, highways, landforms, fast food restaurants)
