Unit 1 and stuff Flashcards
Choropleth Map
A map that shows the average values of property through shading
Isoline Maps
Connection of data points of the same value through lines
Dot Distribution Map
A map that uses dots or other symbols to represent the presence, quantity, or value of a phenomenon or thing in a specific area.
Proportional Symbol Map (Graduated symbol map)
Proportional symbol maps scale the size of simple symbols (usually a circle or square) proportionally to the data value found at that location.
Catogram
Distorting the geometry of regions in-order to convey the information of an alternate variable
Absolute Distance
Absolute distance in geography is a measure of the physical space between two locations.
relative distance
Relative distance is a measure of the social, cultural and economic relatedness or connectivity between two places
Mercator projection
The Mercator Projection was an attempt to create a two-dimensional map that maintained accurate and reliable compass points, and in this it succeeded, but, unfortunately, in doing so it distorted the area of continents and landmasses relative to each other.
map projection (map distortion)
On a map or image, the misrepresentation of shape, area, distance, or direction of or between geographic features when compared to their true measurements on the curved surface of the earth.
time-space compression
Space Time Compression- The reduction in the time it takes to diffuse something to a distant place, as a result of improved communications and transportation system.
Robinson Projection (compromise projection)
The Robinson Projection is something of a compromise in that it attempts to minimize errors in distance, relative size, and compass direction but does not accurately depict any one of these factors wholly.
GIS
A geographic information system (GIS) is a computer system for capturing, storing, checking, and displaying data related to positions on Earth’s surface.
GPS
Global Positioning System. Explanation: Global Positioning System, or GPS, is commonly used to determine an individual’s exact location on Earth.
remote sensing
Remote sensing refers to the process of taking pictures of the Earth’s surface from satellites (or, earlier, airplanes) to provide a greater understanding of the Earth’s geography over large distances.
distance-decay
Distance decay is the name of the theory that states that as the distance between two places increases, the interaction between those two places decreases.
