Geografical location

Print So far, we have learned why geographic data are unique, how information differs from data, and how various forms of geographic information can be represented in computers and communicated to human beings. Let us now consider the types of questions we can ask, now that we are equipped with this knowledge. The simplest geographic questions pertain to individual entities Such questions include:

Geografical location

What Does "Geographic Location" Mean? Your absolute geographic location is defined by two coordinates, longitude and latitude. These two coordinates can be used to give specific locations independent of an outside reference point.

Geografical location

Relative location, on the other hand, defines a location in terms of another. For example, Lille is north of Paris.

These two types of geographic location are useful in different circumstances. Longitude lines run north and south across the Earth, between the two poles. The prime meridian is the zero line for longitude. It runs between the North and South poles, through Greenwich, England. The prime meridian splits the Earth into the Eastern and Western hemispheres; the International Date Line divides the Earth opposite the prime meridian.

The International Date Line is not straight due to social reasons, but all other longitude lines are parallel to the prime meridian.

Latitude lines run across the Earth, perpendicular to longitude. The equator divides the Earth into its Northern and Southern hemispheres. All other latitude lines are parallel to the equator. Lines that are below the equator are southern latitudes, whereas lines that are above the equator are northern latitudes.


Sciencing Video Vault Units of Measurement The units of measurement for longitude and latitude are degrees, minutes and seconds. The Eastern and Western hemispheres each contain degrees of longitude, totaling degrees.

The Northern and Southern hemispheres each contain 90 degrees of latitude, totaling degrees. The minute and second components of these coordinates correspond to more precise divisions between degree lines. Each degree contains 60 minutes, and each minute contains 60 seconds.

Uses of Absolute Geographic Location The coordinate system of geographic location is used to represent specific locations on the globe.

Because longitude and latitude lines form a grid on the Earth, you can pinpoint precise locations with just two coordinates. Hence, these coordinates are extremely useful whenever global navigation is concerned: Global positioning devices, maps and other navigational services benefit from such an accurate way of noting position.

Uses of Relative Geographic Location Relative geographic location is useful for unassisted human navigation. With no instruments, you must rely on natural landmarks and other points of interest to gauge your position. For example, it is probably easier to drive north to Colorado Springs, Colorado, knowing that it is roughly References University of Nebraska-Lincoln: His concerns include such things as categories, language, descriptions, representation, criticism and labor.

He has been writing professionally since Unlike arctic tundra the alpine tundra regions are spread out all over the place on earth.

These are a few areas where alpine tundra is located: Rockies, Sierra, and Cascade Mountains in North America, the Andes in South America, the Himalayas in Asia, the Alps .

St. Martin is a three-and-a-half-hour flight from New York, a two-and-a-half-hour flight from Miami (Florida), an hour and a half away from Caracas (Venezuela), and 45 minutes from the islands of Guadeloupe and Puerto Rico. What is Mahāyāna Buddhism geographical location? It originated in India, but spread to Tibet, China and Central Asia from there.

Today, Mahayana Buddhism is found predominantly in China, Vietnam. A map is the greatest of all epic poems.

A location is the place where a particular point or object exists. Location is an important term in geography, and is usually considered more precise than "place." A locality is a human settlement: city, town, village, or even archaeological site.
