Document Summary
The blue and orange map from 1482 by ptolemy shown in lecture slide is special because it was the first map with coordinates first map ever with grid system. However, this map was completely and totally wrong. Lines going from left to right/side to side (cid:1118) Lines that cut down from top to bottom (cid:1119) Equator: cuts right across the centre of earth-->0 latitude. Arctic circle: the highest you can go when the sun never sets (in summer) or where the sun never rises (in winter) Tropic of cancer, and tropic of capricorn: they are both latitudes. Latitudes go straight across lines i. e. horizontal lines. i. e. equator is a latitude (it cuts right across from left to side) (cid:1118) Parallel: these are the lines that go horizontally. It has the widest girth because it is around the widest part of the earth. Known as the place where the sun never sets in the summer.
