Synopsis:

Altitude system of the Czech Republic. Methods of stabilization of altitude points. Geometric levelling from the centre, technology of precision and technical levelling including errors and accuracy characteristics. Method of trigonometric determination of height differences. Methods of suppressing the effect of refraction on the measured zenith angle. Centering and mathematical reduction of measured quantities. Detailed altimetry measurements include older and newer technologies of the tachymetric method according to the available instrumentation up to the production of the altimetry plan.

Requirements:

no

Syllabus of lectures:

1. Introduction to height measurements. Basic concepts, types of heights,

Methods of height measurements, height system of the Czech Republic, stabilisation and signalling of height points.
