Thermal infrared (TIR) satellite imagery collected by multispectral scanners is important to map land surface temperature on a global scale. However, the TIR spectral bands are typically available in coarser spatial resolution than other of shorter wavelengths. Therefore, derived (LST) limited around 100 m. This constrains applications such thermal sensors which finer detail LST pattern relevant, especially an urban environment where cover structure complex. Among missions deployed Earth’s...

Mapping and modelling the complicated geometry of caves is a challenging task that has traditionally been undertaken by tacheometric surveying methods. These methods are excellent for capturing general shape cave system but they not suitable high-speed, high-resolution mapping complex surfaces found in this environment. Terrestrial laser scanning (TLS) technologies can acquire millions points represented 3-D coordinates, at very high spatial densities on multifaceted within minutes. In last...

Airborne and terrestrial laser scanning close-range photogrammetry are frequently used for very high-resolution mapping of land surface. These techniques require a good strategy to provide full visibility all areas otherwise the resulting data will contain with no (data shadows). Especially, deglaciated rugged alpine terrain abundant large boulders, vertical rock faces polished roche-moutones surfaces complicated by poor accessibility still challenge. In this paper, we present novel...

Abstract. The change of hydrological conditions during the evolution caves in carbonate rocks often results a complex subterranean geomorphology, which comprises specific landforms such as ceiling channels, anastomosing half tubes, or speleothems organized vertically different levels. Studying environments traditionally requires tedious mapping; however, this is being replaced with terrestrial laser scanning technology. Laser overcomes problem reaching high ceilings, providing new options to...

By interpretations related to energy, elementary land surface segmentation can be treated as a physical problem. Many pieces of such view found in the literature combined into synthetic comprehensive approach. The has preceded by defining character and size searched units result from segmentation. A high-resolution digital elevation model (DEM) is key input for this task; it should generalized resolution best expressing information about units. Elementary characterized various parts...

Abstract Over the last few years, many European countries experienced a rapid growth of photovoltaic (PV) power plants. For example, more than 20, 000 new PV plants were built in Czech Republic. The high spatial and temporal variability solar resource subsequent plant production, poses challenges for reliability predictability grid system. In this paper, we analyse most recent data on Republic Slovakia, with focus distribution these installations. We have found that scarcely follow potential...

Abstract. Ice caves can be considered an indicator of the long-term changes in landscape. volume is dynamic throughout year, but inter-seasonal comparison ice dynamics might indicate change hydrological–climatic regime However, evaluating cave a challenging task that requires continuous monitoring based on detailed mapping. Today, laser scanning technology used for cryomorphology mapping to record status with ultra-high resolution. Point clouds from individual campaigns need localised...

The presented study uses the recent colour aerial photographs, historical black and white detailed digital elevation model to assess spatial distribution long-term temporal dynamics of soil loss in agriculturally intensively exploited loess hilly land with a subcontinental temperate climate. strongly eroded soils appear studied area as bright patterns, surrounded by darker soils, they are well visible on photos. Three approaches interpretation photographs were tested: visual interpretation,...

Abstract Caves are unique sedimentary archives that may record the evolution of surrounding landscape. In this study, we applied combination mineralogical data on allochthonous sediments with digital modelling isobase surfaces to reconstruct multi‐phased geomorphological development karst Harmanecká dolina Valley. The cave contain quartz and translucent heavy minerals (HMs) such as tourmaline, garnet, rutile, apatite, zircon, pyroxene, amphibole, staurolite, spinel, monazite, corundum,...

Abstract. Urban greenery has various positive micro-climate effects including mitigation of heat islands. The primary root islands in cities is absorption solar radiation by the mass building structures, roads and other solid materials. absorbed subsequently re-radiated into surroundings increases ambient temperatures. vegetation can stop absorb most incoming mostly via photosynthesis evapotranspiration process. However, mild climate Europe manifests considerable annual seasonality which...

Abstract. High-resolution solar radiation modelling requires the three-dimensional geometric structure of landscape to be respected. Currently, remote sensing methods such as laser scanning and close-range photogrammetry are most commonly used for detailed mapping. The output is 3D models containing buildings, trees, relief other features. raster approach allows modeling energy relief, but it unsuitable objects buildings trees. polygonal features vector mainly designed buildings. Our goal...

Incorporation of a physically-based general geomorphological theory directly into the segmentation algorithm is fundamental to land surface segmentation. Topographical steady state for morphostructural segmentations with five types elementary forms defined by principle equilibrium provides basis definition input variables. Examples application introduce two new geomorphometric variables: Index Steady State (ISS) quantifying closeness regions topographic state; and Slope Disequilibrium (ISD),...
