Opis:
The true digital terrain map (DTM) is needed to calculate so-called terrain gravity potential. It is one of the fundamental factors in earth geoid shape determination. There are many methods of calculation of the gravity potential. The gravity integral should cover all Earth area. There is no possibility to establish digital terrain map for whole planet. So it must be numerically proved, if the gravity integral converges to its extreme value for some limited part of the earth area. The model of DTM was established mathematically for testing a different way of gravity potential calculation. It contains all features of real DTM and has been build up in two steps processing.

Opis:
Airborne Laser Scanning (ALS) products are now often used to study the terrain due to their numerous advantages such as relatively low cost and ease of data collection. The ISOK project (pl: Informatyczny System Osłony Kraju – national hazard protection information system) developed elevation data for about 65% of the Polish territory. Parallel to the airborne laser scanning point cloud collection, additional products, such as orthophotomaps, digital terrain models (DTM), and digital surface models (DSM) were created. This resource is not only a reference material for the project, but also a valuable source of the analysis used in various fields of economy and science. Important features of the ISOK-data are the availability and their standardized format based on uniform technical conditions. The article presents the results of an experiment in which an attempt was made to use the digital elevation model with a resolution of 1 m based on airborne laser scanning data to determine concave terrain features using GIS tools. The ISOK-DTM has a height accuracy of 0.15 m for the outdoor areas, which makes it a better representation of small terrain forms than previous products. The research area is located at an undeveloped open ground with comparatively little variation of its shape for a long period. Several methods were tested to classify the terrain shape based of topographic attributes. Those methods led to similar locations of the concave features and further on coincide with results of the pre-analysis. Also, attention was drawn to the selection of the analysis parameters and their influence on the result. The results show the usefulness of ISOK’s DTM for locating field concave terrain shapes.

Opis:
This paper describes a computationally inexpensive approach to learning and identification of maneuverable terrain to aid autonomous navigation. We adopt a monocular vision based framework, using a single consumer grade camera as the primary sensor, and model the terrain as a Mixture of Gaussians. Self-supervised learning is used to identify navigable terrain in the perception space. Training data is obtained using pre-filtered pixels, which correspond to near-range traversable terrain. The scheme allows for on-line, and in-motion update of the terrain model. The pipeline architecture used in the proposed algorithm is made amenable to real-time implementation by restricting computations to bit-shifts and accumulate operations. Color based clustering using dominant terrain texture is then performed in perception sub-space. Model initialization and update follows at the coarse scale of an octave image pyramid, and is back projected onto the original fine scale. We present results of terrain learning, tested in heterogeneous environments, including urban road, suburban parks, and indoors. Our scheme provides orders of magnitude improvement in time complexity, when compared to existing approaches reported in literature.

Opis:
The aim of this study is to examine and evaluate the effects of long-term stress on muscle and heart biomarkers after completing a 100 km ultramarathon. Material and Methods: Venous blood samples of nine runners (average age 38.8±10.2 years), who successfully finished a 100 km ultramarathon at an elevation of 3130 m, were examined before the start, at the finish line immediately after the run, one day after the run and then after 5 and 10 days. Clinical, laboratory, and somatometric data were obtained from all measurements, and biomarkers: aspartate aminotransferase (AST), cortisol (COR), troponin T (cTnT), creatine kinase (CK) and C-reactive protein (CRP). Also, their training experience and ultramarathon experience was monitored. Discovered values were further analyzed with the use of t-test a ω2 (ω2≥0.1), and Spearman's rank correlation coefficient (r) at the significance level of p<0.05. Results: The average finish time of the runners was 13:55:40 (min: 12:12:35, max: 16:52:02). After finishing the ultramarathon, runners showed an average weight loss of 2.4 kg (p<0.05). The results show that hematological changes were caused by physiological stress and long-term physical load. The values of all monitored biomarkers showed a significant exceeding of the normal values immediately after the race in 8 competitors out of 9. The values of cTnT showed an increase of more than 50 % (pre -race: 8.2±2.3, post-race: 34.22±25.9 ng/l, max=98 ng/l). After 24 hours, however, this condition had returned to the normal values for all participants. The results show that the AST hepatic enzymes significantly correlated with the training experience (r=-0.41, p=0.043), the total number of kilometers run per year (r=-0.45, p=0.04) and the achieved finish time (r=0.67, p=0.001). At the same time, athletes who had the best finish time achieved lower CRP values (r=0.74, p=0.023) and cTnT values (r=0.49, p=0.040). The study found that the competitors who had the longest experience with ultramaraton had the lowest cTnT (r=0.44, p=0.050). Conclusion: Long-term physical stress is associated with metabolic and cardiovascular changes. Blood abnormalities found in our study suggest that due to long-lasting extreme stress, heart exhaustion may occur. However, these changes did not last long and after a few days they returned to the normal values for all runners.

Opis:
This paper presents the results of determining slope values using seven different methods for different resolutions: 1, 5, 10, 30, 90 meters for the Bystra catchment area. After calculating the slopes using different methods for different resolutions, the following slope ranges were created: 0.00o–2.99o, 3.00o–5.99o, 6.00o–9.99o, 10.00o–14.99o and ≥15o into which the corresponding pixels were included. The results of slope calculations were compared with geodetic field measurements of slopes in the vicinity of Esterka castle in Bochotnica, which is located in the Bystra catchment area. It was found that the good reproduction of the actual terrain relief, represented by the 1 m resolution Digital Terrain Model (DTM), deteriorates significantly starting from 30 m resolution. The method for determining terrain slopes that most accurately represents the true relief variability is the 2nd Degree Polynomial Adjustment method (Zevenbergen et al., 1987). The results of the analyses are crucial for determining the minimum quality of DTM data.In this study, high resolution data (1 m, 5 m, 10 m) were found to be suitable for analysis and interpretation of terrain slopes in a small catchment. The results of the study show what resolution of DTM should be used for other studies: morphometric, geomorphological or hydrological of small catchments, where the quality of results is important e.g. in accurate water balance analysis of catchments or soil erosion analysis in agriculture.

Opis:
Underwater terrain aided navigation is applicable to underwater vehicles during long missions. It relies on a prior known ocean bathymetric map and collected in-situ sonar data to determine the position of the vehicle. The performance of the navigation system depends on the sea floor characteristics and algorithms that are used to match those two sets of data. In this paper, a novel idea was proposed to treat bathymetric maps and in-situ sonar data as images. A variety of existing algorithms developed for image processing can be applied to obtain position fixes. Textual features extraction, image interpolation and image registration were tested using available bathymetric data and synthesized sonar data as collected in-situ. Simulation results indicate that the chosen image analysis methods are capable of providing robust position fixes. The image characteristics extracted from the underwater terrain data are shown to be rotation and scale invariant. As the resolution of multi-beam bathymetry sonars keeps improving with technology advances, the use of image analysis techniques facilitates underwater terrain aided navigation for a wide range of new applications.

The overall objective of the research is to summarize tactical considerations, resulting from terrain and weather analysis, to support the preparation, planning and execution of subterranean operations. The study used the Grounded Theory for collection, analysis, and systematic treatment of data. The main data sources for the study consisted of purposive sampling from operations in subterranean systems and lessons learned from them. Two new sub-variables are now proposed to be included in terrain and weather variable from mission analysis model for subterranean operations: Subterranean system’s location and accesses and subterranean system features. The key to finding subterranean systems is through terrain analysis, physical ground search, operational indicators, and intelligence products. The analysis of the features of the subterranean system and its mapping is critical for developing courses of action. Forces must be trained and equipped to manoeuvre and combat at short distances and poor visibility conditions. Surface access points and command and control bunkers usually are assessed as key terrain. Obstacles placed at intersections are excellent ambush sites. Accessing sophisticated structures requires specific techniques and equipment. Inside the subterranean systems, existing angles, barriers, walls, cavities, stairwells and other objects provide cover and concealment. Water can make it impossible to build subterranean systems, place obstacles, or even use them; droughts can “create” new avenues of approach. Clouds and fog difficult the detection of subterranean systems. The terrain and weather analysis model, the characteristics, and the tactical considerations presented, all combined, support the preparation, planning, and execution of operations in subterranean systems.

Świadomy dobór parametrów skanowania oraz strategii przetwarzania obrazu na tym etapie technologicznym zadecyduje o jakości danych cyfrowych, a w konsekwencji również o jakości produktu końcowego. W artykule zostanie przeanalizowany wpływ wybranych param etrów skanowania na jakość automatycznie wygenerowanego numerycznego modelu terenu przy użyciu fotogram etrycznej stacji cyfrowej. Do najistotniejszych parametrów procesu, w kontekście niniejszego zadania, zaliczono wybór sposobu skanowania (kanału), rozdzielczość oraz przyjęty stopień kompresji. Doświadczenia prowadzono na stacji cyfrowej ImageStation 2000, w programie ISAE (ImageStation Automatic Elevation) wykorzystując zdjęcia kolorowe w skali 1:26000 co pozwoli na zastosowanie uzyskanych wyników badań w produkcji krajowej. Wyniki przeprowadzonych eksperymentów zostaną ukazane na tle dotychczasowych doświadczeń innych autorów.

Opis:
Digital photogrammetry is one of the intensively developing areas of technical sciences. Increasing participation in the surveying works have digital devices and solutions giving new possibilities in creation of the appropriate map elements and models as well. A particular role to play has the laser scanning technology allowing to present surveyed space or area in the 3D form. Digital Terrain Models for agricultural areas obtained on its basis may be presented in different ways using professional software. Due to the fact, that in recent years almost the entire Poland was covered with laser scanning, collecting information about the Earth’s surface in the form of a cloud of points with high accuracy is a relatively fast process and the results of their elaboration are widely used in many fields. The paper presents the methods of Digital Terrain Models visualization of agriculture areas for three different objects created on the basis of data derived from airborne laser scanning. The study included agricultural locations - two of them (Strzelce Wielkie and Kamionka Wielka) located in the Malopolskie Voivodship, the third - Mątowy Wielkie in Pomorskie Voivodship, in Żuławy. DTM visualizations were prepared in Macrostation, Terrasolid and Surfer 10 software. For the Mątowy Wielkie object the Digital Surface Model (DSM) was created additionally.
