The establishment of both local and national geodetic networks belongs to the field of higher geodesy. Geodetic equipment and methods intended for high-precision measurements are used to perform work in the field of higher geodesy.
The Estonian national geodetic main network is in good condition and its supplementation and reconstruction are carried out only for specific special needs (for example, when geodetic points are destroyed). Local geodetic main networks are not in such good condition. Despite this, reconstruction of local networks is also carried out mainly only when geodetic points are destroyed.
The multi-level geodetic network being built for the construction of Rail Baltic can also be classified as geodetic main networks. With its number of geodetic points reaching hundreds and probably even thousands, this geodetic network will probably be the biggest challenge for geodetic works in Estonia during the entire construction period of Rail Baltic. A significant part of the Rail Baltic geodetic network will be built by Inseneribüroo REIB OÜ.
In addition to the construction of geodetic main networks, high-precision geodetic measurements are also used in some measurements within the field of engineering geodetic work (for example, subsidence observations, deformation measurements, geodetic monitoring).
