Opis:
Should an oil spill of tier III magnitude occur in the Northern Adriatic, there is a high probability that the oil will reach and pollute the surrounding coastline. Therefore, it is vital to conduct coastal vulnerability studies to develop priority plans and coastal vulnerability maps to help first responders protect the coastline. As there is no common contingency plan for oil spills in the Northern Adriatic, three countries, Italy, Slovenia, and Croatia, which share the area, decided to participate in the North Adriatic Incident Response System (NAMIRS) project. Part of the project was to conduct a coastal vulnerability study in the area. One of the three pillars for determining vulnerability, in addition to the ecological and geomorphological factors, is the socioeconomic aspect, which was studied as part of the research. As there are no clear scientific methods to determine the vulnerability of the socio‐economic factors, a survey was conducted where the participants gave their subjective opinion on its value. This was done through three workshops organised in each participating country, where professional stakeholders familiar with the state of socio‐economic activities assessed their vulnerability. The values obtained were combined with the assessments of the geomorphological and environmental factors and gathered in a coastal vulnerability layer, which was incorporated into a GIS as a standard coastal vulnerability map that will help first responders prioritise coastal protection. The research results will also be useful globally and not just in the area studied by NAMIRS, since the method used is readily applicable to any part of the world.

Opis:
This paper studies the assessment of sensitivity to land degradation of Deliblato sands (the northern part of Serbia), as a special nature reserve. Sandy soils of Deliblato sands are highly sensitive to degradation (given their fragility), while the system of land use is regulated according to the law, consisting of three zones under protection. Based on the MEDALUS approach and the characteristics of the study area, four main factors were considered for evaluation: soil, climate, vegetation and management. Several indicators affecting the quality of each factor were identified. Each indicator was quantified according to its quality and given a weighting of between 1.0 and 2.0. ArcGIS 9 was utilized to analyze and prepare the layers of quality maps, using the geometric mean to integrate the individual indicator map. In turn, the geometric mean of all four quality indices was used to generate sensitivity of land degradation status map. Results showed that 56.26% of the area is classified as critical; 43.18% as fragile; 0.55% as potentially affected and 0.01% as not affected by degradation. The values of vegetation quality index, expressed as coverage, diversity of vegetation functions and management policy during the protection regime are clearly represented through correlation coefficient (0.87 and 0.47).

Opis:
Zasady czułości sensora pojedynczego fotonu są w proponowanym referacie przedstawione i porównane z najnowocześniejszym zgodnym ze sztuką skanerem typu full waveform (pełny kształt fali) W referacie wyjaśniono różnice teoretyczne obydwu rozwiązań, a dane dotyczące obu technologii są oceniane na podstawie danych pozyskanych dla miasta Wiednia w 2018 r. odpowiednio za pomocą sensorów: SPL100 (Leica) i VQ-1560i (Riegl). Chociaż SPL ma wyższą wydajność powierzchniową, dane pełnego kształtu fali okazują się bardziej precyzyjne, szczególnie w złożonych sytuacjach docelowych, takich jak naturalne lub strome powierzchnie. Ponadto, artykuł podsumowuje aktualne działania w ramach EuroSDR dotyczące potencjalnego testu porównawczego LIDAR dla danych pojedynczego fotonu i trybu liniowego.
In this short paper, the principles of single photon sensitive LiDAR are presented and compared against state-of-the-art full waveform, linear-mode LiDAR. The differences are explained in theory, and data of either technology are evaluated based on the City of Vienna dataset, captured in 2018 with the SPL100 (Leica) and VQ-1560i (Riegl), respectively. While SPL features a higher areal performance, waveform LiDAR turns out to be more precise, especially in complex target situations like natural or steep surfaces. Furthermore, the article summarizes current activities within EuroSDR concerning a potential Single Photon and linear-mode LiDAR benchmark.
