The aim of the article is to present selected experience with updating the digital technical map (DTM) dataset in the Czech Republic after 2 years of its widespread introduction into operation. The subject of the analyses was the methods of initial filling of the basic spatial situation (ZPS) data with new mapping of land roads and defined territories of technical infrastructure administrators. When updating the ZPS, accuracy problems of vectorization from LIDAR mobile mapping data and problems of the results of p...

The paper deals with the experience of engineering geological surveys of problematic sections of motorways D47 and D2 in the Czech Republic. Into selected sections of the D47 motorway near Ostrava waste material of blast furnace slag was deposited, which proved to be very problematic. Another problem solved was the solution of surface and embankment defects of the D2 highway near the town of Hustopece, located in Moravia, where in some places there have been surface drops of up to several centimeters. In the emban...

Safety monitoring is of particular importance for building structures at the end of their lifetime what could endanger the health and lives of people. The use of geodetic robotic measuring stations enables the automated acquisition of coordinate data on the spatial position in the key locations of the monitored building construction and from them to evaluate geometric deformations in real time. This concerns the monitoring of large roof structures of sporting arenas, particularly in winter under snowfall impact, o...

This paper describes the optimized algorithm for searching Hamiltonian path in graph. Formerly a similar algorithm was developed for the finding of the optimized path in terrain for finding of the precise positioning of Global Navigation Satellite Systems (GNSS) via Real Time Kinematics (RTK) method. The aim of this method is to achieve quality GNSS observation on all the points in question, so that the total length of the path within all these points can be minimized. There are nodes of two types in the graph: 1)...

The article presents our own solution of a monitoring information system developed on base of experience learned from completed projects. Information system integrates automated data collection by geodetic and non-geodetic sensors, and presentation of data through a web interface. The measuring part of the system supports data collection by multiple types of sensors. At present are pluggable leveling sensors (Leica DNA03, Leica Sprinter), GNSS sensors (Leica System 1200), 3D sensors (robotic total station Topcon G...
