GR 100 Lecture Notes - Lecture 1: International Date Line, Azimuthal Equidistant Projection, Gangnido
Document Summary
Spatial analysis: distribution (density, concentration, and pattern, movement (distance, distance decay, diffusion) Systems analysis: earth systems (lithosphere, biosphere, atmosphere, etc. , city systems (sewer, street, water, etc. ) The kangnido (korean map made in 1492) Coordinate system: latitude: horizontal lines (north vs south, longitude: vertical lines (east vs west) Mercato map: preserves angles, but not area. Mollweide map: preserves area, but not angles. Cylindrical map: squashes the north and south to try to preserve area. Azimuthal equidistant projection map: things close to center of map are accurate in area, but things towards the edges are distorted. Robinson projection map: appears to be realistic, but is not actually accurate. Map scale: relates distance on the map to the real world: verbal scale: 1 inch to 1 mile , fraction scale: 1/62500, graphic scale: ruler-like measure on the bottom of the map. Map types: location, general purpose, reference, topographic: mainly shows elevation, thematic: can show population, population change, languages, political parties, etc.
