Key Geographical Concepts
Primary Data
Data sourced by yourself (i.e a drawing made by you)
Secondary Data
Data that someone else has made and is used for personal research (i.e reading a journal).
Relative Distance
Measure of distance between two points; measures approx. time of travel.
Absolute/Linear Distance
Measure of distance between two points; measures total distance and direction.
Place
A specified area within a country, land or in the world.
Absolute Location
Precise record of place, involving geographical coordinates.
Relative Location
Description of location of place by using another location respective to it, measuring total distance and direction.
Region
Distinguishable area in the earth’s surface due to characteristics from any other area.
Movement
The direction of something/phenomena of changing of location.
Described by arrows, thin means less, thick means more in density
Map Scale
Describes relationship of map measurements and actual measurements on the ground.
Two kinds;
- Linear (described by arrows, thin means less, thick means more in density)
- Ratio (i.e 1:100,000. Every 1cm = 100,000cm on earth (1km))
Observational Scale
Conceptual measurement of scale, determined/studied by size of region. Separated into different levels;
- Local
- Regional
- National
- International
- Global
Can be disasters, distribution of product, etc.
Distribution
Patterns, features, and objects that can be assessed through PQE and Spatial Association (if making comparison).
PQE: (Pattern (distribution of something), Quantification (how it can be measured/evidence of such distribution), Exception (outliers within map))
Spatial Association: Assessing the strength of relationship/association (strong, moderate, or weak).
Change
Changes that can be found overtime in different places, scales etc.
Interconnection
Relationships between factors related to each other in a variety of ways (i.e. people and organizations).
