Vocab Unit 1 Flashcards
maps used to show land forms and/or places
reference map
maps used to display specific types of information (theme) pertaining to an area
thematic map
thematic map that shows statistical data by transforming space e.g. population
cartogram
thematic map that uses shading or coloring to show statistical data e.g. population
choropleth map
thematic map that uses dots to indicate a feature or occurrence e.g. population
dot density 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
graduated symbols map (proportional symbols map)
the way things are laid out and organized on the surface of the Earth
Spatial pattern
hierarchy of spaces
e. g. location of French speakers
global: in the world
regional: in North America
national: in Canada
local: in Quebec
Spatial scale
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 distortion
a way to transfer the 3-dimensional earth onto a 2-dimensional map to reduce distortion in area, distance, shape, and/or direction
map projection
information that identifies the geographic location of features and boundaries on earth (natural and constructed)
geographic data
technology that provides geographic data that is used for personal (navigation), business (marketing), and governmental (environmental planning) purposes
geospatial technologies
- 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
- data is displayed and analyzed to gain insights into geographical patterns/relationships
GIS
Geographic Information system
system of satellites that provide geo-spatial positioning
e.g. GPS
Satellite navigation systems:
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
remote sensing
