Unit 1.1 Introduction to Maps Flashcards
Remote Sensing
The process of capturing images of Earth’s surface from airborne platforms such as satellites or airplanes
Global Positioning System (GPS)
The system that accurately determines the precise position of something on Earth via satellites and recievers
Geographic Information System (GIS)
A computer system that captures, stores, analyzses and displays georgaphic data
Layers
Types of information (countries, bodies of water, names of places etc.) displayed in a map
Mashups
The practice of combining layers on a map
Qualitative Data
Data associated with a humanistic approach to geography
Quantitative Data
Data associated with mathematical models and statistical techniques
Latitude
The distance north or south of the equator
Equator
An imaginary line that circles the globe exactly halfway
Longitude
The distance east or west of the Prime Meridian
Prime Meridian
An imaginary line that runs from pole to pole through Greenwich, England
Map Key/Legend
An inset on a map that explains what the colors or symbols used means and what the scale of the maps is
Map Scale
The ratio between the size of things in the real world and the size of things on a map
Toponym
The name given to a place on Earth
Relative Location
The description of where something is in relation to other things
Absolute Location
The precise place where something is found
Relative Distance
The distance between two points, measured using metrics like time effort or cost
Absolute Distance
The distance between two points, communicated using precise quantative units of measurements
Relative Direction
The direction based on people’s surrounding and perception
Absolute Direction
Directions according to a compas (NSEW)
Density
How often or how much something occurs within a place
Distribution
Where something occurs within a place
Clustered
When there is a high level of density and a low level of distribution
Dispersed
When there is a low level of density due to a high level of distribution
Distance Decay
The theory that the interaction (flow of goods, people) between two places decreases as the distance between them increases
Time-Space Compression
The reducation in the time it takes to diffuse something to a distant place, as the result of improved communication and transportational technologies
Physical Geography
The study of the spatial characteristics of various elements of the physical environment (landforms, bodies of water, climate, ecosystems etc.)
