GOODE’S INTERRUPTED PROJECTION
- An equal-area projection.
- The projection quite accurately presents the
size and shape of the continents.
- Distances- especially in the oceans- are less
accurate.
GOODE’S INTERRUPTED PROJECTION
DRAWING MAPS
- A Map Projection is a way of drawing the
earth on a flat piece of paper.
MERCATOR PROJECTION
- One of the earliest types of maps drawn.
- Created by Gerardus Mercator in 1569.
- This type of projection shows land shapes fairly
accurately, but not size or distance.
MERCATOR PROJECTION
ROBINSON PROJECTION
-
The Robinson projection shows both the size
and shape of oceans and continents quite
accurately.
-
Textbook and atlas maps are often Robinson
projections.
ROBINSON PROJECTION
HEMISPHERES
-One-half of the globe.
- The Equator divides the earth into Northern
and Southern Hemispheres.
- - The Prime Meridian divides the earth into
Eastern and Western Hemispheres.
HEMISPHERES
LATITUDE AND LONGITUDE
Latitude- Distances measured in degrees North and
South of the Equator at 0 degrees latitude.
- The Letters N or S following the degree symbol tells
you if the location is north or south of the Equator.
- The North and South poles are at 90 degrees North
(N) and South (S) Latitude.
LATITUDE AND LONGITUDE
Longitude is distance measured in degrees East (E) or
West (W) of the Prime Meridian at 0 degrees
longitude.
Lines of latitude and longitude cross each other in the
form of a grid system.
- Knowing a place’s latitude and longitude allows you to
locate it exactly on a map or globe.
- You can name an absolute location by naming the
latitude and longitude lines nearest to that location.
