Supervisor:

Department of Geomatics

Synopsis:

Landsurveying in terrain is intended for the practice of measurement methods of geodesy and data processing work in the creation of a point field.

Includes tasks:

Long Range Triangulation and Trilateration (TRG)

Determining the course of the quasi-geoid (GEO)

Remeasurement and adjustment of height points with very precise leveling (VPN)

Azimuth determination using the gyrotheodolite, gravimetric measurements

Requirements:

Active participation in the measurement and processing of all tasks.

Processing of technical reports in designated groups.

Syllabus of lectures:

Long Range Triangulation and Trilateration (TRG)

- determining of the coordinates of four points in the JTSK system using classical geodesy methods (triangulation, trilateration, astronomical azimuth determination)

GNSS calculation:-determining the coordinates of four points in the ETRS89 system by a fast static GNSS method.

Determining the course of the quasi-geoid (GEO)

- determination of the course of the quasi-geoid in the profile along the leveling program of the II order Z7ab Žleb-Kunčice using GNSS leveling. The achieved results will be used to test the CR2005 quasigeoid model in the given area.

Recovery and alignment of the leveling program with very precise leveling (VPN)

- within the framework of the task, the restoration of part of the leveling program of the II order Z7ab Žleb-Kunčice in the section Nová Seninka - Kladské sedlo will be carried out

Determination of direction by gyrotheodolite - determination of the azimuth of the side of the triangular network by the method of azimuth measurement using a gyrotheodolite

Gravimetric measurements - determination of gravitational acceleration using a static spring gravimeter measurement method as a basis for calculating normal heights

GNSS fast static method

- GNSS measurement and determination of the coordinates of the specified point in the S-JTSK system

Calculation in LGO - phase measurement calculation in the Leica Geo Office program
