Geography terms
azimuth
a compass direction expressed as an arc area clockwise from the north through 360 degrees
DMS Coordinates
divided the circle into 360 degree with each degree subdivided into 60 minutes (60'). and each minute further subdivided into (60")
GMT Greenwich Mean Time
former world standard time, now known as Coordinated Universal Time (CUT)
Parallel
A line connecting all points at the same latitudinal angle is called a parallel.
isogonal map
A map showing isogons
isogon
An isoline connecting points of equal magnetic declination.
Another parallel
Arctic circle
Local Sun Time
OR SOLAR TIME IS BASED ON THE ACTUAL LONGITUDINAL ARC DISTANCE ( IN DEGREE, MINUTES, AND SECONDS) BETWEEN A LOCATIOON AND THE PRIME MERIDIAN.
Other parallel
Tropic of Capricorn
scale
a map is a scale model of the ground. The scale tells the distances and sizes of things on the ground
Small Circles
are circles whose centers do not coincide with earth's center.
Antipodes
are points on the globe that are diametrically opposite each other that would be at either end of a line drawn through the center of the earth like the north and south Pole.
Prime Meridian
both the longitude is the name of the angle, meridian names the line and both indicate distance east or west of an arbitrary prime meridian.
Longitude
is an angular or arc distance east or west of a point on earth's surface measured from the center of earth.
Latitude
is an angular or arc distance north or south of the equator ( the line running east and west halfway between the poles, measured from the center of Earth.
Great Circle
is any circle of Earth's circumference whose center coincides with the center of Earth. An infinite number of great circles can be drawn on Earth.
Corresponding parallel
is the Tropic of Cancer
Meridian
names the line that connects all points at the same longitude.
Linear distance
spanned by a degree of longitude is greatest at the equator where meridians separate to their widest distance apart and diminishes to zero at the poles where they converge.
IDL International Date Line
the starting point for each new day. Since the Date Line is the standard (controlling) meridian for a time zone, no change in time occurs when crossing the line, only the date. (p10).
