Globes and Map Projections

Globes and Map ProjectionsGoode’s Interrupted ProjectionGoode’s projection is called an equal area projection.It accurately presents the size and shape of continents.Distances in the ocean are less accurate.Mercator projection The Mercator projection shows land and shapes fairly accurately, but does not correctly calculate size or distance. It is use for sea travel because it shows true direction.http://www.socialstudiesforkids.com/articles/geography/mercatorprojection.htm What continent appears the largest on the Mercator projection? Robinson ProjectionThe Robinson projection shows both size and shape of oceans and continents accurately. These are the projections usually found in textbooks and Atlas publications.Vocabulary for Lesson One:projectiongrid systemhemisphereabsolute locationlatitudegreat circle routelongitudeWinkle Triple Map Projection – The standard map projection used by the National Geographic Society. The lines of latitude curve gently around the “poles” and the lines of longitude do not meet in a tight knot at the poles. The land areas are less distorted than that of the Robinson projection. http://www.mapcomaps.com/catalog/wallmaps/world/natlgeoworldphysocean.html Hemisphereshttp://www.worldatlas.com/aatlas/newart/hemispheres.gif Longitude and LatitudeThe latitude lines are shown for every 10 degrees, starting at the equator; the longitude lines are shown for every 15 degrees, starting at the prime meridian. Both longitude and latitude are expressed as a certain number of degrees plus a direction - N, S, E or W!"Example:The North Pole is at 90° North (N) latitude, and the South Pole is at 90° South (S) latitude.*The letters N or S that follow the degree symbol tells you if the location is north or south of the Equator. Longitude is measured going East and West of the Prime Meridian. Question?What is the International Date Line?
