a map line connecting points of equal or very similar values
large scale
a relatively small ratio between map units and ground units. large-scale maps usually have higher resolution and cover much smaller regions than small-scale maps.
the angular distance north or south of the equator, defined by lines of latitude (parallels) - from 0 to 90 degrees
law of retail gravitation
a law stating that people will be drawn to larger cities to conduct business since larger cities have wider influence on the surrounding hinterlands

mathematically transferring Earth's sphere onto a flat surface. also describes the resulting type of map. always has distortions in area/direction/distance/shape
map scale
the ratio between the size of an area on a map and the actual size of that area on Earth's surface
