Civil aircraft navigation uses specific procedures for the continuous determination of the aircraft position using the path and distance traveled in the considered time interval as calculation elements. Throughout the route, errors must be estimated that are generated by a series of parameters such as: hydrometeorological conditions, air current direction, declination, geoid parameters, the ship's nautical qualities and the response mode of the navigation equipment. The indications of the magnetic compass must be ...

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 aim of the article is to present modern geodetic methods used for surveying sacral buildings. These are terrestrial surveying, photogrammetry and drone images. When surveying the building, the digital sketch method was used, which, in addition to the geometry, also captures the topology of the resulting drawing of the surveyed object. The benefit of this method is the automated drawing of a wireframe model of the building in a CAD application. The platform used is QGIS with Python language support. The advanta...
