A geodetic reference datum is a known and constant surface which is used to describe the location of unknown points on Earth. Since reference datums can have different radii and different center points, a specific point on Earth can have substantially different coordinates depending on the datum used to make the measurement. There are hundreds of locally developed reference datums around the world, usually referenced to some convenient local reference point. Contemp… WebA sphere is based on a circle, while a spheroid (or ellipsoid) is based on an ellipse. A spheroid, or ellipsoid, is a sphere flattened at the poles. The shape of an ellipse is defined by two radii. The longer radius is called the semimajor axis, and the shorter radius is called the semiminor axis. landhaus ottulahttp://ecoursesonline.iasri.res.in/mod/page/view.php?id=124960 assen 2007

Web23.1 Projection System. A projected coordinate system is defined on a flat, two-dimensional surface. Unlike a geographic coordinate system, a projected coordinate system has constant lengths, angles, and areas across the two dimensions.

WebThe resulting datums were typically limited in extent and were tied to an origin point on the earth's surface. The North American Datum of 1927 (NAD27) is a classic example of an early, local earth-surface-based datum. The spheroid NAD27 uses Clarke 1866 that originates at a surface point at Meades Ranch, Kansas.
