science of map making
map projections in which the meridian converges at the poles; the parallel appears as equally spaced, concentric circles
conic projection
line on a map connecting points with the same elevation
contour line
contour line with short, straight lines drawn along the inside of the loop pointing toward its center that indicates a depression
depression contour
height above sea level
point on the earth’s surface above a pole of the earth’s imaginary internal magnet
geomagnetic pole
map projections in which the parallels appear as unevenly spaced, concentric circles, the meridians appear as straight lines radiating from a central point, and all other circles appear as straight lines
gnomonic projection
every fifth contour line on a topographic map that is printed bold for reference
index contour
any circle that divides the globe in half
great circle
angular distance north or south of the equator
list of map symbols and their meaning
angular distance east or west of the prime meridian
angle between the direction of the earth’s geographic pole and the direction in which a compass needle points
magnetic declination
flat map that represents a three-dimensional curved surface
map projection
mean sea level
point midway between the highest and lowest tide levels of the ocean
map projection in which the meridians appear as straight, parallel evenly spaced lines and form a grid with the parallels which appear as straight, parallel, and unevenly spaced lines
Mercator projection
semicircle on the earth that runs from pole to pole
any circle that runs east and west around the earth parallel to the equator
map made by fitting together a series of conic projections of adjoining areas
polyconic projection
the meridian that passes through Greenwich, England, designated as 0 degrees
Prime meridian
differences in elevation between the highest and lowest points of an area
relationship between distance shown on a map and actual distance
map that shows the surface features of the earth
topographic map
surface features of the earth
direction of the geographic North Pole
true north
