Geographical distance or geodetic distance is the distance measured along the surface of the Earth, or the shortest arch length. The formulae in this article calculate distances between points which are defined by geographical coordinates in terms of latitude and longitude.
Lines of latitude (also called parallels) are imaginary lines that circle Earth’s surface, running east and west parallel to the Equator. Lines of longitude (also called meridians) run between the geographic North Pole and the geographic South Pole and are used to measure distances from the prime meridian.
Location, Distance, and Direction on Maps. Most maps allow us to specify the location of points on the Earth's surface using a coordinate system. For a two-dimensional map, this coordinate system can use simple geometric relationships between the perpendicular axes on a grid system to define spatial location.
19 paź 2023 · distance north or south of the Equator, measured in degrees. longitude. noun. distance east or west of the prime meridian, measured in degrees. minute of latitude. noun. measurement of about 1.8 kilometers of latitude north or south of the equator. parallel. adjective.
EMPLOYING THE GEOGRAPHIC sense of the term, distance can be defined as the amount of separation between two points or objects on the surface of the Earth. Geographic distance is usually expressed as a linear measurement between locations using one of several commonly accepted metrics (a metric is a standard of measurement using associated units).
27 kwi 2024 · One degree of longitude corresponds to a specific distance on Earth’s surface, but unlike latitude, the exact distance varies depending on where it is measured. At the equator, where the Earth is widest, one degree of longitude is approximately 69.172 miles (111.321 kilometers).
19 paź 2023 · Longitude is measured by imaginary lines that run around Earth vertically (up and down) and meet at the North and South Poles. These lines are known as meridians. Each meridian measures one arc degree of longitude. The distance around Earth measures 360 degrees.
