Earth’s shape = Geoid Figure 1.11

Maps, Scales, and Projections Cartography- the part of geography which embodies map making Map- a generalized view of an area, usually some portion of the Earth’s surface, as seen from above and greatly reduced in size
7
The Geographic Grid b) Longitude (Meridians) 1 degree of longitude = 111 km at the equator and 0 at the poles a) Latitude (Parallels) 1 degree latitude = a constant 111 km

Latitude is the angle between a point on a parallel and the center of the Earth and a point on the equator Figure 1.13
