Unit 1 Flashcards
Reference Maps
Reference maps are designed for people to get specific information about places, typically natural features or the location of cities, towns, etc.
Thematic Maps
These maps describe different spatial patterns (clustered, dispersed, random) of attributes and statistics. The types of maps include, Isoline/Topographic, Cartograms, Choropleth, Dot Density, Graduated Symbol.
Chloropleth Map
A map that uses shading, coloring, or even symbols to represent different data values. For example population and unemployment rates.
Dot Density Map
A map that uses dots the density of dots to symbolize the number of features in an area.
Isoline Map
An isoline map uses lines to connect data of the same values.
Graduated Symbol Map
A map with symbols that vary in size according to the density of the feature they represent. Proportional symbol maps are another name for graduated as it’s used interchangeably.
Cartogram Map
Cartograms use color or distortion to represent different data values as well. The distortion separates itself from other maps.
Absolute Location
Exact location of the Earth using longitude and latitude.
Absolute Distance
The exact distance of 2 different places. Uses a determined unit of measurement. The distance can be determined using a scale.
Absolute Direction
Correlates to the direction of a compass. Combinations of North, East, South, and West
Relative Location
A description of how location is related to the places that are near it.
Relative Direction
Describes a place based off its direction.
Relative Distance
Measure of cultural, social, and economic connectivity between 2 places.
Elevation
The height above a certain level or to which something is raised.
Distortion
Altering the original shape of something.
Census Data
The population totaled of a certain area at a certain time.
Satellite Imagery
Photos of the Earth’s surface collected from sensors on orbiting satellites. The sensors record portions of the electromagnetic system allowing humans to view patterns + processes.
GPS
Satellites that orbit the earth send radio signals to help map-based apps give directions.
GIS
Software application meant to store/check data related to the Earth’s positioning.
Quantitative Data
Data that is usually associated with a measurement of some sort. It expresses a certain amount of something. Considered factual
Qualitative Data
Data that describes attributes/properties of something.
Space
Area of the Earth’s surface.
Place
Physical/human characteristics of a place anywhere on earth. The place gives space meaning.
Distance Decay
The idea the further you go from an idea/topic the harder it is to fully comprehend said idea/topic.
Patterns
Arrangement of something in an area. For example, linear patterns are straight patterns like chairs lined up, centralized patterns are patterns concentrated in one place, and random patterns are patterns with no specific order.
Expansion Diffusion
When ideas spread among regions but still stay rooted and strong in the original region.
Relocation Diffusion
The idea that when people move they spread ideas along with them. Stimulus, contagious, and hierarchical diffusion are types of relocation diffusion.
Sustainability
The ability to stay maintained at a certain level.
Natural resources
Materials/resources that are drawn from nature.
Possibilism
The belief that humans can overcome the limitations that the environment gives.
Global Scale of Analysis
The entire level of the earth. It identifies patterns that are relevant to the whole world.
Regional Scale of Analysis
Comparing two nations or provinces within’s data/ideas.
National Scale of Analysis
The level of a region. also identifies patterns that are relevant to that region.
Local Scale of Analysis
The data of a city or country of a certain state/province
Formal/Uniform Region
A geographical area that is occupied by people with similar traits.
Functional/Nodal Region
A self-sufficient region tends to be near an area that surrounds a focal point (node). Organized to be one unit.
