What Is Neogeography? > Basic Terminology

Basic Terminology

Several useful terms are essential to discussing neogeography. Some are familiar, while others have specific contexts within a broader meaning. They are presented here for later referral as you progress through the book and are listed in a logical order so that terms build upon one another:

Coordinates

The geographic coordinates are the absolute position on the Earth (or any body). Typically these are Latitude and Longitude referenced to the WGS84 ellipsoid. Sometimes they will be referred to as "lat" and "lon." Latitude varies North-South, with 0 degrees at the Equator, varies from 90 to −90 degrees towards the poles, and is positive North. Longitude varies East-West, with 0 degrees at the Prime Meridian, varies from 180 to −180 degrees and is positive to East.
