| cartogram | a map on which statistical info is shown in diagrammatic form |
| cartographer | a person who makes maps |
| spatial patterns | ways in which people, places, and characteristics are organized on the Earth's surface |
| reference maps | Maps that show the absolute location of places and geographic features determined by a frame of reference, typically latitude and longitude |
| thematic maps | maps that tell stories, typically showing the degree of some attribute or the movement of a geographic phenomenon |
| absolute location | exact location of a place on the earth described by global coordinates |
| relative location | the position of a place in relation to another place |
| map projection | a way of representing the spherical earth on a flat surface |
| Mercator Projection | a true conformal cylindrical map projection map projection, this projection is particularly useful for navigation because it maintains accurate direction. This projections are famous for their distortion in area that makes landmasses at the poles appear oversized. |
| Robinson Projection | projection that attempts to balance several possible projection errors. It does maintain completely accurate area shape, distance, or direction, but it minimizes errors in each. |
| Galls-Peters Projection | a projection that is politically correct because Africa and South America are the correct relative size. Accurate area, inaccurate shape |
| Winkel Tripel Projection | most common for world maps today. Balances size and shape while reducing distortion |
| distortion | a change in the shape, size, or position of a place when it is shown on a map. |
| clustering | the tendency to put similar or related items in groups |
| dispersal | movement of individuals away from centers of high population density or their area of origin |
| elevation | height above sea level |
| absolute distance | the distance that can be measured with a standard unit length, such as a mile or kilometre |
| relative distance | approximate measurement of the physical space between two places |
| choropleth maps | A thematic map that uses tones or colors to represent spatial data as average values per unit area. |
| dot distribution map | A map where dots are used to demonstrate the frequency or intensity of a particular phenomena |
| graduated symbol map | A map with symbols that change in size according to the value of the attribute they represent. |
| isoline map | A type of thematic map that transforms space such that the political unit with the greatest value for some type of data is represented by the largest relative area. ... Maps that use lines to represent quantities of equal value. Lines spaced close together indicate a rapidly changing value. |
| mental map | A map which represents the perceptions and knowledge a person has of an area |
