Geodetic Point

Geodetic Point

 

a point on the earth’s surface, the location of which is fixed in a certain system of coordinates and altitudes on the basis of geodetic measurements.

The coordinates of a geodetic point are determined mainly by the method of triangulation. In this case, a geodetic point is called a point of triangulation or a trigonometric point. If the coordinates of a geodetic point are fixed by the method of polygonometry, then it is called a polygonometric point. The altitudes of geodetic points are determined by the method of leveling. In general, points of triangulation and polygonometric points do not coincide with points of leveling. Points of triangulation, polygonometric points, and leveling points are designated and secured at the site by means of special markers set up for the purpose. The system of mutually connected geodetic points forms the geodetic network, which serves as a basis for the topographical study of the earth’s surface and for all sorts of geodetic measurements for various needs of engineering and the national economy.

As well as allowing the mapping of India, it was also very important from a geodetic point of view.
The app is functionally focused on displaying and working interactively with digital data from the real estate registry, ZBGIS data, the address registry, referential geodetic points, raster maps from the archive as well as the digital terrain model and geographic names.This data is integrated into one unit, allowing users to obtain more comprehensive information about a particular territory not only from the point of view of current ownership but also from the point of view of topography, said UGKK chair Maacuteria Frindrichovaacute.
Triangular geodetic rosettes constructed on the network of the existing geodetic points were applied to the definition of the state of the surface deformation of two landslides varying in the degree of the activity and the origin.
