GEOG 131 Lecture Notes - Lecture 2: Antarctic Circle, Hurricane Harvey, Spatial Analysis
Document Summary
Problems with hurricane harvey: catastrophic ooding due to it being slow moving, power outages > high winds, tornadoes, storm surge > affects sea walls. Latitude=parallels: concentric circles parallel to one another- same distance from pole, 0 degrees is the equator, each latitude approximately 69 miles apart, measured in north and south, important latitudes to know. Longitude=meridians: pole to pole- not parallel- converge at poles, 0 degrees is the prime meridian, each longitude approximately 15 degrees apart which equal 1 hour, measured in east and west. It was 1773 when they could correctly determine longitude and time. Sea level= 1013 millibars: increase in atmosphere, pressure decreases. Map scales- represent scale with a ratio of distance on map to same distance on the ground : representative fraction: large scale= small area, more detail, small scale= large area, less detail. Gps (global positioning system: three parts.
