Abstract
The author analyzes current methods of 3D documentation of historical tunnels in Skorkov village, which lies at the Jizera river, approximately 30 km away from Prague. The area is known as a former military camp from Thirty Years’ War in 17th Century. There is an extensive underground compound with one entrance corridor and two transverse, situated approximately 2 to 5 m under the local development. The object has been partly documented by geodetic polar method, intersection photogrammetry, image-based modelling and laser scanning. Data have been analyzed and methods have been compared. Then the 3D model of object has been created and compound with cadastral data, orthophoto, historical maps and digital surface model which was made by photogrammetric method using remotely piloted aircraft system. Then the measuring has been realized with ground penetrating radar. Data have been analyzed and the result compared with real status. All the data have been combined and visualized into one 3D model. Finally, the discussion about advantages and disadvantages of used measuring methods has been livened up. The tested methodology has been also used for other documentation of historical objects in this area. This project has been created as a part of research at EuroGV. s.r.o. Company lead by Ing. Karel Vach CSc. in cooperation with prof. Dr. Ing. Karel Pavelka from Czech Technical University in Prague and Miloš Gavenda, the renovator.
Highlights
1.1 The Skorkov townSkorkov with its 583 inhabitants (CSO, 2015) is a town lies approximately 30 km north-east from Prague, the capital of the Czech Republic
The aim of the research was to check the current situation of the underground object with using many geodetic and photogrammetric methods, laser scanning, RPAS and ground penetrating radar (GPR), to collect surveying data with measuring under the surface and above surface and analyse those data
In Skorkov village the underground object was measured by several methods
Summary
Skorkov with its 583 inhabitants (CSO, 2015) is a town lies approximately 30 km north-east from Prague, the capital of the Czech Republic. The main sight in Strokov is the St. Jan Křtitel Church (the first record in 1359) with ossuary and the altar in the Renaissance style and the adjacent parish from 1910, (joined together with near village Sojovice). The town is very popular and often visited by cyclists and thanks to the magnificent river Jizera it is a paradise for fish men. According to the locals, during The Thirty Years' War were two military camps divided by Jizera river – the Emperor’s Army and Swedish Army. That is why during the local football matches could be the flags of these countries seen still today
