• remote sensing - gathers info from satellites that orbit earth or other craft above the atmosphere
• aerial photography - a photograph taken from an aircraft, especially one that is flown at a high altitude
• landscape analysis - defining and describing landscapes
• field observation - a method of gathering data by observing

  people the natural environment
• spatial data - info that can be tied to specific locations
• global positioning system (gps) - a satellite navigation system that uses a network of satellites to determine the location of a receiver
• geographic information systems (GIS) - a computer system that allows users to analyze and display geographic data
• geovisualization - 2D and 3D interactive maps
• spatial approach - the arrangement of the phenomena being studied across the surface of the earth
• site - the characteristics at the immediate location of a structure, such as the location of a building or the location of a road
• situation - the location of a place relative to its surroundings and its connectivity to other places
• toponyms- place names
• time space compression - shrinking “time-distance”, or relative distance, between locations because of improved methods of transportation and communication
• friction of distance - when things are farther apart, they tend to be less connected
• distance decay - the further away from the source, the weaker the signal gets
• spatial association - matching patterns of distribution
