Latitude The angle of the North star in the sky is equal to one’s latitude.
Longitude
Coordinates
Projections The Earth is a three-dimensional sphere. In order to map it onto a two-dimensional map certain features must be distorted. Mercator Projection Equal Area Projection Conic Projection
Projections Lines of Longitude are parallel Poles become distorted
Projections The area of each section is the same Distortion near edges
Projections Longitudinal lines are parallel, while latitudinal lines are curved. Size and shape of land is accurate Only works for small areas.
Topographical Maps Topographical maps show the change in elevation over a landscape.
