Learn how to measure and communicate positions on Earth using latitude and longitude, and how different geodetic datums affect the coordinates. Explore the history and standards of the geographic coordinate system and its applications in cartography and geodesy.
Local coordinates are used in a local coordinate system or a local coordinate space, such as houses, addresses, or computer graphics. They are different from global coordinates, which are based on a global system of reference, such as geographic coordinate system or geodetic datum.
Movement is one of the five themes of geography, along with location, place, human-environment interaction, and region. Movement is the travel of people, goods, and ideas from one location to another, and it connects places and regions.
Economic geography is the subfield of human geography that studies economic activity and factors affecting it. It has diverse methodological approaches, theoretical backgrounds, and thematic branches, such as geography of agriculture, trade, development, and globalization.
Learn how to obtain and add geographic coordinates to Wikipedia articles from various sources, such as maps, online services, directories, databases and calculators. Find out the preferred geotagging templates and the licensing information for different tools.
Learn how astronomers, cartographers and navigators discovered a means of determining the longitude of any place on Earth. The invention of the chronometer by John Harrison in the 18th century was a major breakthrough for accurate navigation at sea.
UTM is a map projection system that assigns coordinates to locations on the Earth's surface, ignoring altitude and treating the Earth as a perfect ellipsoid. It divides the Earth into 60 zones, each 6 degrees of longitude wide, and uses a transverse Mercator projection with a standard scale factor of 0.9996.
Geopositioning is the process of determining or estimating the geographic position of an object using various methods and systems. Learn about the principles, techniques, and applications of geopositioning, such as GPS, celestial navigation, and visual fixes.
