The document discusses the essential element of geography known as the World in Spatial Terms. It explains that spatial relations refers to how locations are connected due to their position on Earth's surface. There are two types of location: relative location, which is a location's position in relation to other places, and absolute location, which uses lines of latitude and longitude to precisely locate any place on Earth without referring to other objects. Absolute location was originally needed for navigation at sea using a grid system of latitude and longitude lines that crosses the entire globe.
