| Term | Definition |
|---|---|
| contour | A contour is a line on a topographic map that represents locations that have the same altitude. |
| azimuth | An azimuth is the angle that a line makes with a meridian (a line of longitude), going clockwise from north. |
| archipelago | An archipelago is a group or chain of islands clustered together in a sea or ocean. |
| sinusoidal projection | A sinusoidal projection is a type of map projection in which lines of latitude are parallel to the equator, and lines of longitude are curved around the prime meridian. |
| quadrangle | A quadrangle is a four-sided area bounded by two lines (parallels) of latitude and two lines of longitude (meridians) on a map. |
| planar projection | A planar projection is a type of map in which the details of the globe are projected onto a plane (a flat surface) yielding a rectangular-shaped map. Cylindrical maps have a lot of distortion towards the edges. |
| planimetric map | A planimetric map is a map that represents only the horizontal positions of features (and not the vertical positions, like heights, which a topographic map shows). |
| Orthographic projection | An Orthographic projection is a type of map which is essentially a drawing of (one side of) a globe. There is a lot of distortion of area in this type of map, but one gets the idea that the globe is being represented. |
| geomorphology | Geomorphology is the scientific field that investigates how landforms are formed on the Earth (and other planets). |
| geographical coordinate system | A geographical coordinate system is a system that uses latitude and longitude to describe points on the spherical surface of the globe. |
