The objective of the study is to reconstruct the bathymetry of a shallow river using the Structure-from-Motion algorithm and to evaluate the robustness of the approach by exploring its repeatability and reproducibility. To address this issue, the multi-UAV experimental campaign was organized in SW Poland/N Czechia, and focused on the smoothly flowi...

This article focuses on the need to improve current knowledge of sedimentation and erosion processes in small reservoirs on the example of the Pocheň reservoir (Czech Republic). We combined data from sediment cores, with unmanned aerial vehicle imaging and ground-penetrating radar survey. The results show the distinct sediment distribution and the...

This paper describes the process of very high-resolution thermal mosaic acquisition using low-altitude airborne remote sensing and the basic analysis of data regarding urban climate research. The process of data acquisition from flight planning to final mosaicking is described. A broadband thermal camera was mounted to a Cessna aeroplane for two fl...

One-decade long observations of post-cut-off channel development and oxbow lake formation are presented to offer insight into the morphological response of the Morava River to neck cut-off (during spring flood, 2006). The main objectives were: calculation of the amount of sediment released to the channel by collapse of meander neck; comparison of f...

This paper explores the potential of the joint application of unmanned aerial vehicle (UAV)-based photogrammetry and an automated sensor network for building a hydrodynamic flood model of a montane stream. UAV-based imagery was used for three-dimensional (3D) photogrammetric reconstruction of the stream channel, achieving a resolution of 1.5 cm/pix...

This paper presents a new non-invasive technique of granulometric analysis based on the fusion of two imaging techniques, Unmanned Aerial Vehicles (UAV)-based photogrammetry and optical digital granulometry. This newly proposed technique produces seamless coverage of a study site in order to analyze the granulometric properties of alluvium and obse...

The main aim of presented paper is to find the most realistic and preferred color settings for four different types of surfaces on the aerial images. This will be achieved through user study with the use of eye-movement recording. Aerial images taken by the unmanned aerial system were used as stimuli. From each image, squared crop area containing o...

In this paper authors processed five satellite image of five different Middle-European cities taken by five different sensors. The aim of the paper was to find methods and approaches leading to evaluation and spatial data extraction from areas of interest. For this reason, data were firstly pre-processed using image fusion, mosaicking and segmentat...

Rivers are naturally dynamic over time and space and respond to the variability of water and sediment inputs and to anthropogenic pressures that cause changes to the river’s shape and form. The present form of river channels is influenced by past events. It is impossible to perform landscape studies without quality aerial or satellite images. UAVs...

The central part of Bohemian Forest represents important headwater region in central Europe, which plays important role in runoff generation. The area that is recently preserved at both Czech and German side as the National Park (Šumava National Park and Nationalpark Bayerischer Wald, respectively) has in past decades undergone extensive forest dis...

This paper explores the potential of Unmanned Aerial Systems (UASs) for the analysis of variations in the fluvial dynamics of a mid-mountain stream. The UAS photogrammetry was employed to acquire a multitemporal set of high-precision digital terrain models (DTMs) and orthoimages, thereby enabling the reconstruction of variations in riverbed and qua...

Rivers are naturally dynamic over time and space and respond to the variability of water and sediment inputs and to anthropogenic pressures that cause changes to the river's behaviour and form. This study describes the evolution of part of the Morava River and the Kenický meander in the Litovelské Pomoraví protected area near the city of Olomouc. T...

Geodetic measurements and monitoring are traditional methods of the observation of landslides, and slope movements processes in general. The precision of measurements is usually an important task, as well as the expended amount of time and money are important. It is not necessary to reach sub-centimetre precision in case of the regular monitoring o...

This paper discusses a proposition of the landslide monitoring system within the framework of the project on modeling of the relation of landslide displacement and rainfall in the Czech flysch Carpathians, using wireless, remote sensing and GIS techniques. Its main objective is to develop a model which would reveal this relation, and to that end, a...

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 scientific benefit arises from the combination of knowledge achieved by conventional field work and the visual info...

Příspěvek se zabývá projevem zvýšené míry intenzity osobní automobilové dopravy na suburbanizaci mezi územím města Olomouce a jeho zázemím. Cílem výzkumu bylo na základě dat intenzit dopravy (Celostátní sčítání dopravy v letech 2000 a 2005) a autory provedeného měření v roce 2010 provést temporální analýzu intenzit dopravy a výsledné změny porovnat...

Visualization of geospatial data: chaos in the dimensions. - Geografie-Sborník CGS, 114, 3, pp. 169-178 (2009). - 2D maps, 2.5D terrain models and 3D visualization are examples of terms which are widely used in computer science, geography, cartography and also in geoinformatics. What do they, however, really mean? The paper tries to clarify the com...
