This paper investigates the potential of Global Navigation Satellite System (GNSS) technology for monitoring vertical displacements in areas affected by underground mining and evaluates its combination with precise geometric leveling. The study is based on repeated measurements carried out in the Stonava locality (Czech Republic), where intensive deep coal mining induces significant surface subsidence reaching up to several decimeters per year. The main objective is to assess the accuracy of GNSS-derived heights, ...

Mobile handheld laser scanning is already an established technology in today's surveying practice. Mobile handheld scanners are mostly used for surveying and 3D rendering of indoor spaces. However, the subject of this paper will be the area of real estate cadastre. The aim of this paper is to verify the capabilities of mobile handheld laser scanning technology for cadastre of real estate purposes. The paper will focus specifically on surveying activities related to the production of a survey sketch for designation...
