The methodology of applying the modern digital cameras (SLR-type) and terrestrial laser scanning for surveying of mining objects (dimension stone blocks), reception of the information on a camp of rock mass, recognition of cracks in rock massif with following definition of their geometrical parameters, quality control of dimension stone blocks on quarry are considered. The m...

A rise of a mean global sea level recorded during the 20th and 21st century is one of the most important indicators of climate change, which induces the thermal expansion of the oceans (steric effect) and ice melting. The mean rates of global sea level rise are estimated at around 3.1 mm a year. Those rates are routinely calculated from tide gauge measurements and satellite altimetry. However, regional rates that are driven by local geophysical processes can vary significantly. Thus, the impact of sea level change...

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 пїЅphoto busпїЅ (a mobile m...

In the process of documenting cultural heritage, traditional techniques have left their place to digital techniques, as their efforts to acquire the right data in the shortest time have developed in technology in recent years.The most common of these techniques is the terrestrial laser scanning technique and the terrestrial photogrammetry technique. In the documentation of cultural heritage, the level at which these methods are used today is quite pleasing. The greatest advantage of these methods is that it enable...

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,...

The uncontrolled water flooding in an abandoned open pit mine modifies the rock mass stability, causing rock wall falls and surface erosion that may affect great volumes of material. As regards Sardinia quarries, most of the open pit excavations need a recovery plan. The last mostly depends upon knowledge of the relationship between the geomorphological asset and the nature of weathering and related erosion processes. The aim of this paper is to evaluate the land degradation with a detailed photogrammetric survey ...

There are a lot of traces of wars or military activities throughout the Czech Republic. You can find fortifications from Roman times to the Cold War. In 2009, a big project started in the Czech Republic пїЅ aerial laser scanning of the whole national territory. It was finished in 2013; since this year there has been a possibility to use very precise digital terrain models (DTM), a new face of the landscape mainly in forested areas, derived from aerial laser scanners and INS instruments. For archaeology, the use of...

Remotely Piloted Aircraft Systems (RPAS), which have become more popular in recent years, can obtain data on demand in a short time with a resolution within centimeters. Data collection is environmentally friendly and low-cost from an economical point of view; of course it is best for small areas, such as square kmпїЅs, only by using winged drones or in a few hectares by use of multi-copters. Both types have their advantages and disadvantages. Our laboratory of photogrammetry has, since 2012, focused on using RPAS...

Historical artifacts are not inherited to us, but are the most precious works we will pass on to future generations.Documentation and preservation of historical works is one of the common tasks of human being. Historical artifacts are constantly eroded and worn over time in natural and unnatural ways. The restoration and consolidation of these structures should be taken as a whole in their work. Measurements and modeling of the work should be made from technological developments. The terrestrial photogrammetry tec...

Orthorectification is main and specific photogrammetric task. Digital technologies allow generation of precise orthoimages, whic h are obtaining the pixel accuracy. The realization of this process requires usage of precise and adequate object model that is generated by usage of different data sources. They include irregular set of points created by survey measurements, digitized cartographic data, raster DEM obtained from stereo pairs, or from points’ cloud gathered by laser scanning. The main steps of orthorect...

The data used in this st udy were optical remote sensing satellite images Landsat TM (22-08-1986) and Landsat ETM+ (23-06-2002). These images were pro...

The present study has been carried out with the use of Remote Sensing techniques in combination with Geographical Information Systems/GIS for monitoring and protection of the environment, in the surroundings of mining areas, as well as for developing new techniques for searching for new Mn-ore deposits, in Drama area, Northern Greece. Various digital processing techniques were applied on LANDSAT-TM imagery. These techniques included differe nt methodologies, such as the “Principal Component Analysis” (PCA), вЂ...

A various range of remote sensors are currently available to help to explore a landscape and other natural components. The mainly part of this field is based on a small format aerial photographs (SFAP) taken from a small aircraft. The scienti fic benefit arises from the combination of knowledge achieved by conventional field work and the visual information gleaned from SFAP. In monitoring studies, temporal changes of forms and patterns give additional clues. The coupling of field data and interpretation of SFAP...

System FOTOM 2009 on NetBeans platform. On the Department of Informatics FEI V\vSB TU Ostrava FOTOM is developer syst\'em FOTOM, which serves the digital image processing. The program is created in the programming language C++. Originally the system was developed as a purpose-built program with no public API for other future modules. For this mason we decided to create a whole new generation system based on modern language and built on a suitable platform, enabling full modularity of the system. This calls for a r...

Being located in mountain region, Rawa Danau Nature Reserve is the only one wetland area in the mountain region in Indonesis which formed very important component of its biophysical and physical environment. With the decreasing control of the local government and private agencies over the years, and rapid urban sprawl of the city, many of the water bodies have been totally lost. This has been converted to wet rice field cultivation and also expansion of illegal logging. One of our greatest environmental challenges...

Recent advances in remote sensing have changed conventional ways of collecting and processing elevation data. Especially Light Detection and Ranging (LiDAR) has become one of the leading technologies for rapid acquisition of elevation data. In this paper we present a system for digital elevation model (DEM) construction from LiDAR data. First, we present a visualization technique that allows efficient representation for LiDAR data processing. This makes the data segmentation, which is the key step in DEM generatio...
