How we interact with each other in places and across spaces
How we make sense of others and ourselves in our localities, regions, & the world
Types of maps
Reference maps
Thematic maps
Reference maps
Maps used to show landforms and/or places
Types of reference maps
Physical map
Political map
Physical map
Reference map that shows identifiable natural landmarks such as mountains, rivers, oceans, elevation
Political map
Reference map that shows political boundaries e.g. countries, cities, capitals, etc.
Thematic maps
Maps used to display specific types of information (theme) pertaining to an area
Types of thematic maps
Cartogram
Choropleth map
Dot density map
Graduated symbols map (proportional symbols map)
Cartogram
Thematic map that shows statistical data by transforming space
Choropleth map
Thematic map that uses shading or coloring to show statistical data
Dot density map
Thematic map that uses dots to indicate a feature or occurrence
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
Types of spatial patterns represented on maps
Absolute distance
Relative distance
Absolute direction
Relative direction
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)
Absolute direction
Finding a location using compass direction e.g. north, south, east, west
Relative direction
Finding a location not using compass direction e.g. left, right, forward, backward, up, down
Spatial pattern
The way things are laid out and organized on the surface of the Earth
Types of spatial patterns
Clustering
Dispersal
Elevation
Clustering
Objects that form a group e.g. coastal population
Dispersal
Objects that are scattered e.g. rural population
Elevation
Height above sea level
Spatial scale
Hierarchy of spaces
Spatial scale example
Global: in the world
Regional: in North America
National: in Canada
Local: in Quebec
Map projections inevitably distort spatial relationships in shape, area, distance, and direction
Map distortion
All maps are distorted as a result of projecting a 3-dimensional surface onto a 2-dimensional surface in area, distance, shape, and/or direction
Map projection
A way to transfer the 3-dimensional earth onto a 2-dimensional map to reduce distortion in area, distance, shape, and/or direction
Data may be gathered in the field by organizations or by individuals
Geographic data
Information that identifies the geographic location of features and boundaries on earth (natural and constructed)
Geospatial technologies
Technology that provides geographic data that is used for personal (navigation), business (marketing), and governmental (environmental planning) purposes
GIS (Geographic Information System)
Map created by a computer that can combine layers of spatial data
Data is displayed and analyzed to gain insights into geographical patterns/relationships
GIS examples
Vulnerability of the Florida Aquifer
School boundaries
Crime rates
Satellite navigation systems
System of satellites that provide geo-spatial positioning
Satellite navigation system example
GPS
Remote sensing
Collecting data with instruments that are distant from the area of study
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
Online mapping and visualization
Compilation and publication of web sites that provide graphical and text information in the form of maps/visuals
Online mapping and visualization example
Homicide statistics
Spatial information can come from written accounts
