A geodetic coordinate system is a three-dimensional coordinate system that is used to precisely locate points on the Earth's surface. It is based on the principles of geodesy, which is the science of measuring and understanding the Earth's shape, size, and gravity field.
In a geodetic coordinate system, a point on the Earth's surface is defined by its latitude, longitude, and height above a reference ellipsoid. Latitude measures the angular distance north or south of the Equator, while longitude measures the angular distance east or west of a prime meridian (usually the Greenwich Meridian).
The height component of a geodetic coordinate system is typically measured as an elevation above or below mean sea level. This height is often referred to as the orthometric height.
Geodetic coordinate systems are widely used in various applications, such as surveying, mapping, navigation, and geodesy. They provide a standardized and accurate framework for depicting and analyzing spatial data on the Earth's surface.
Geodetic surveying is a branch of surveying that involves the measurement and mapping of the Earth's surface, specifically for the purpose of determining the exact positions of points on the Earth's surface. Geodetic surveying considers the Earth as a three-dimensional object and takes into account factors such as the Earth's curvature, the shape of the Earth, and the Earth's gravitational field. This type of surveying uses highly accurate and precise techniques to determine the precise coordinates of points on the Earth's surface, which are essential for activities such as mapping, construction, and navigation. Geodetic surveys are often conducted using advanced instruments such as GPS receivers, total stations, and satellite-based positioning systems.
Geodetic latitude is a concept in geography and geodesy that refers to the angle between the equatorial plane and a line perpendicular to the reference ellipsoid at a specific location on the Earth's surface. It is used to describe the precise position of a point on the Earth, taking into account the shape of the planet as an oblate spheroid, rather than assuming it to be a perfect sphere. Geodetic latitude is measured in degrees and ranges from -90° (south pole) to +90° (north pole).
