This paper presents current research done under the GEMINI (Geospatial monitoring of green infrastructure using terrestrial, airborne and satellite imagery) project. GEMINI is a scientific project of the Faculty of Geodesy, University of Zagreb and Croatian Forest Research Institute funded by the Croatian science foundation. The project aims to explore new knowledge about the green infrastructure (GI) monitoring. The study area of the research is the capital of Croatia, the city of Zagreb. One of the main goals of...

This paper presents an application of photogrammetrical methods for called IBMR (image based modeling and rendering) in comparison with using of several laser scanning techniques. At the CTU (Czech Technical University) in Prague, Laboratory of Photogrammetry, new methods of 3D objects documentation is tested as the long term project. There are two main approaches in documentation: precise documentation by several techniques as precise close range stereo ? fotogrammetry and laser scanning or simple documentation b...

An open source tool?s popularity has increased considerably, as well as micro aerial vehicles (MAV) technologies based on open source hardware. An open source software and hardware delivers a wide variety of applications and technology. The world?s most successful open source projects have their roots in the academy, and now its participation includes a wide variety of academic programs and research. Based on open source technology, a case study has been designed and performed, in order to prove this technology me...

The wide availability of unmanned aerial vehicles (UAVs) equipped with GPS, inertial system and a digital camera makes them very affordable for many geospatial applications. Just about a decade, such applications were reserved exclusively for aerial photogrammetry. With the development and popularization of UAVs, the software was developed, that allows a very high degree of automation in the preparation of standard photogrammetric products, such as digital orthophoto (DOF) and digital terrain model (DTM). However,...

Our research deals with the possibilities of finding and documenting the historical field fortifications of the Thirty Years' War (1618-1648) in the Czech Republic. The archaeological site that was investigated is located in the western part of the Czech Republic, between T?ebel and Vysok? Sedli?t? villages in Tachov district. Terrestrial laser scanning, winged RPAS (Remotely Piloted Aircraft System) and geophysical instruments GPR (Ground Penetrating Radar) and a magnetometer were used to prospect and document th...

The scope of this paper encompasses the comparison of photogrammetric measurement techniques with satellite RTK measurements. The aim of the research is to compare and combine the measurements taken by using three different techniques as well as to determine which of them is the most precise compared to the results of satellite RTK surveying. To convey the research, four measuring sets were used: a GPS receiver, a mobile laser scanner, UAV (unmanned aerial vehicles) as well as so-called ?photo bus? (a mobile mappi...

Modelling studies continue to play an important role. One of such study is stress determination in the reinforcement bars of reinforced columns and determine column's axis deformation. The article presents measurements results of control points located on the model of reinforced concrete column. The column was compressed in few series till it's destruction. In this studies, photogrammetric method and total station measurements were used. The main goal was to use photo points located around column with known coordi...

This paper has been written in conjunction with a public contract for the restoration of the partially lost and destroyed building documentation of the Church of the Assumption of the Virgin Mary at Hlu??n-Darkovi?ky in the territory of the Czech Republic, the contracting authority of which was the Roman Catholic Church. The requirement was the complete provision of measurement in the field and the collection of data, their subsequent processing and the interpretation of the results with the subsequent development...
