Unit I: Ways to Show Earth’s Surface

Objective I will understand how globes, photographs, computer images, and maps show the surface of the Earth

Globes The major difference between the Earth and globe is a scale What is a scale? The area a given space on a map corresponds (matches) to in the real world

Photographs Aerial Photographs: Photographic images of the Earth’s surface take from the air Satellite images: Pictures of the Earth’s surface taken from a satellite in orbit

Geographic Information Systems (GIS) GIS: Computer based systems that store and use information linked to geogrpahic locations. Why is GIS useful? Helps geographers, mapmakers, government agencies, and businesses collect information on places

Map Projections What is a major problem with showing the globe on a map? The Earth is round Distortion: Loss of accuracy in the size or position of objects on a map Projections: Ways to map Earth on a flat surface

Mercator Shows correct shapes and directions but not true distances; Used by sailors; Mercator the Navigator

ROBINSON Nearly correct size and shape of most land areas but the edges are distorted; Robinson is rounded

POLAR Shows the pole, north or south; used by airline pilots
