A set of numbers that represents a specific location on the Earth's surface. Geographic coordinates can be in latitude and longitude, or in another coordinate system such as Universal Transverse Mercator.
A system for storing, manipulating, and analyzing geospatial data. GIS software can be used to create maps, perform spatial analysis, and manage geographic data.
An XML-based language for encoding geospatial data. GML can be used to represent points, lines, polygons, and other types of features.
The imaginary surface of the Earth that best fits its gravity field. The geoid is used as a reference surface for measuring elevation and for mapping the Earth's surface.
A JSON-based format for encoding geospatial data. GeoJSON can be used to represent points, lines, polygons, and other types of features.
The process of determining a location, typically using GPS or other similar technology. Geolocation can be used to find the coordinates of a specific location, or to find the location of a given set of coordinates.
The study of the Earth's physical features, including its rocks, minerals, and fossils. Geology can be used to understand the Earth's history and the processes that have shaped its surface.
The science of measuring and managing the Earth's physical features. Geomatics is used to collect, analyze, and store geospatial data.
The branch of mathematics that deals with the properties and relations of points, lines, surfaces, solids, and higher dimensional analogues.
The process of extracting geographic information from text, typically in order to create geographic features or extract coordinates.
