Choropleth Map
Thematic map that uses shading or coloring to show statistical data; e.g. population
Cartogram

Graduated symbols map (proportional symbols map)
Thematic map that indicates relative magnitude of some value for a geographic region in which the symbol varies in proportion to data; e.g. population
Absolute Distance
measurement using a standard unit of length; e.g.mile, kilometer
Relative Distance
measurement of the social, cultural, and/or economic connectivity between places (how connected or disconnected); e.g. USA and Iran vs USA and China

Geospatial Technologies
Technology that provides geographic data that us used for personal (navigation), business (marketing, and governmental (environmental planning) purposes
GIS (Geographic Information Systen)
-Map created by a computer that can combine layers of spatial data
- Data is displayed and analyzed to gain insights into geographical patterns/relationships; e.g. vulnerability of the Florida Aquifer, school boundaries, crime rates

Types of Remote Sensors: Satellites, planes, aircraft, spacecraft, ships, buoys
Uses of remote sensing:
- Track storm systems
- Search for natural resources
- Military surveillance
-Monitor Volcanoes
-Monitor deforestation/glacier melting
Census Data
Systematically acquiring and recording information about the members of a given population.
Satellite Imagery
Images of earth collected by satellites operated by governments and businesses around the world.
