Looking at the World: Map Projections. When mapmakers create maps, they have to present the round Earth on a flat surface -- this creates some distortions.

Charting Our World

Warmup On your warmup sheet, please put today’s date in the Date column Please write “persuasive writing” as your warmup Answer the following question on a separate sheet of paper: How long does something/someone have to be gone/dead for research to be considered “anthropology/archaeology” versus “grave robbing”?

Cartography Cartographer: The creation of maps including projection and design A person who draws or produces maps Cartographer:

Map Projection Definition: representing the spherical earth on a plane (flat) surface It is impossible to transform a sphere into something flat without creating distortions in the 2-D image. Geographers use numerous mathematical equations to produce map projections.

Mercator Projection Most common map projection since 1569 Distorts the size & shape of the continents (especially Greenland & Antarctica) Meridians do not converge

Conic Projection Not geometrically accurate. Better for regional or hemispheric maps

Interrupted Projection Show’s true size and shape Distances are inaccurate and map is broken in many places

Robinson’s Projection Scales vary throughout the map More distortion at the poles World map used by National Geographic since 1988

Azimuthal Projection Size & distances distorted the further away you get from the starting point Distances between two places are accurate on a straight line through the starting point only Used for aviation
