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:
The article presents the generalized results obtained from the analysis of oil pollution of surface waters in the fields of the Far North. The research considered the administrative territorial division of the Russian Federation, the territory of the Khanty-Mansi Autonomous Okrug – Yugra (KhMAO). The results of the study performed on the basis of field data on sampling for the year were presented. The influence of the hydrocarbon content in surface waters and snow cover was assessed. The aim of the work was to consider the snow cover as a natural source of pollutants, affecting the accumulation in surface waters and snow cover. The results obtained can be used for subsequent observations of snow cover and surface waters. The data obtained can serve as a basis for planning further research and developing the solutions for environmental protection in the Far North. The analysis of the dependencies between the indicators of hydrocarbon pollution in surface waters and snow cover was carried out using the methods of correlation and parametric multivariate regression analysis. The methods of geoinformation analysis and GIS technologies were also used in the work. It was revealed that the problem of the state of snow cover and its role as an indicator of atmospheric and soil pollution require further research. On the one hand, the snow cover detains metals, and polluted soil areas are formed locally, on the other hand, after the snow melts, the pollutants remaining on the surface with surface runoff enter rivers and are carried by the wind for quite long distances.

Opis:
Bluetooth beacons are becoming increasingly popular for various applications such as marketing or indoor navigation. However, designing a proper beacon installation requires knowledge of the possible sources of interference in the target environment. While theoretically beacon signal strength should decay linearly with log distance, on-site measurements usually reveal that noise from objects such as Wi-Fi networks operating in the vicinity significantly alters the expected signal range. The paper presents a novel mobile Geographic Information System for measurement, mapping and local as well as online storage of Bluetooth beacon signal strength in semireal time. For the purpose of on-site geovisual analysis of the signal, the application integrates a dedicated interpolation algorithm optimized for low-power devices. The paper discusses the performance and quality of the mapping algorithms in several different test environments.

Opis:
This article analyzes topographical and geological settings in the Japan Archipelago for comparative raster data processing using GRASS GIS. Data include bathymetric and geological grids in NetCDF format: GEBCO, EMAG2, GlobSed, marine free-air gravity anomaly and EGM96. Data were imported to GRASS by gdalwarp utility of GDAL and projected via PROJ library. Methodology includes data processing (projecting and import), mapping and spatial analysis. Visualization was done by shell scripting using a sequence of GRASS modules: ‘d.shade’ for relief mapping, ‘r.slope.aspect’; for modelling based on DEM, ‘r.contour’ for plotting isolines, ‘r.mapcalc’ for classification, ‘r.category’ for associating labels, and auxiliary modules (d.vect, d.rast, d.grid, d.legend). The results of the geophysical visualization show that marine free-air gravitational anomalies vary in the Sea of Japan (–30 to above 40 mGal) reflecting density inhomogeneities of the tectonic structure, and correlating with the geological structure of the seafloor. Dominating values of geoid model are 30–45 m reflecting West Pacific rise, determined by deep density inhomogeneities associated with the mantle convention. Sediment thickness varies across the sea reflecting its geological development with density of 2 km in its deepest part and thinner in central part (Yamato Rise). The aspect map and reclassified map express gradient of the steepest descent.

Opis:
The security environment is evolving dynamically and analysis of is the task of work security managers. To analyse the security environment we need different data. There are currently online databases published on the publicly accessible data warehouse, as well as web map servers, often in the form of eg. Underlying topographical data used for analysing. Another source of data is the Statistical Office and other authorities or police. Spatial analyses often provide a different view of the monitored phenomenon. Crime mapping is a valuable source of data for the analysis of the security environment. An advantage can be considered the identification of risk areas as well as the monitoring of changes in the extent and location of risk places. The second advantage is the ability to focus only on the analysis of selected offenses that can help, for example, in the monitoring of selected social groups. Crime mapping results are important sources of data for comprehensive analysis of the security environment at the city level. This is confirmed by the results of mapping crime in Kosice for the years 2010 to 2015 presented in this article.

Semantic analysis, outlined in previous paper (W. Pomianowski 2005), has been applied to three GIS packages. ArcGIS and Maplnfo are commercially successful and popular mapping tools, Aviso was conceived by author and is not yet available to the public. The analysis revealed that common set of terms is used in three systems, but the meaning beyond them is different. Graphics style metaphor is most uniform in three systems. ArcGIS and Aviso seem to be closely related in the way they build upon map and layer metaphors, while Maplnfo suffers from inconsistencies, terminological confusion and lazy coding. The strength and high abstraction level of metaphors is not crucial for casual cartography, however it becomes important for advanced cartographic projects, where map long term maintenance is a major factor.

Opis:
Noise mapping is a well-established practice among the European nations, and it has been follow for almost two decades. Recently, as per guidelines of the Directorate General of Mines Safety (DGMS), India, noise mapping has been made mandatory in the mining expanses. This study is an effort to map the noise levels in nearby areas of mines in the northern Keonjhar district. The motive of this study is to quantify the existing A-weighted time-average sound level (LAeq, T) in the study area to probe its effects on the human dwellings and noise sensitive areas with the probability of future development of the mines, roads, and industrial and commercial zone. The LAeq, T was measured at 39 identified locations, including industrial, commercial, residential, and sensitive zones, 15 open cast mines, 3 major highways, and 3 haulage roads. With the utilisation of Predictor LimA Software and other GIS tools, the worked out data is mapped and noise contours are developed for the visualisation and identification of the extent and distribution of sound levels across the study area. This investigation discloses that the present noise level at 60% of the locations in silence and residential zone exposed to significantly high noise levels surpasses the prescribed limit of Central Pollution Control Board (CPCB), India. The observed day and night time LAeq, T level of both zones ranged between 43.2–62.2 dB(A) and 30.5–53.4 dB(A), respectively, whereas, the average Ldn values vary between 32.7 and 51.2 dB(A). The extensive mobility of heavy vehicles adjoining the sensitive areas and a nearby plethora of open cast mines is the leading cause of exceeded noise levels. The study divulges that the delicate establishments like schools and hospitals are susceptible to high noise levels throughout the day and night. A correlation between observed and software predicted values gives R2 of 0.605 for Ld, 0.217 for Ln, and 0.524 for Ldn. Finally, the mitigation measure is proposed and demonstrated using a contour map showing a significant reduction in the noise levels by 0–5.3 dB(A).

The authors of the review aim to understand and assess cartographic Heat Maps' (HM) designs, tools, and applications. The paper consists of two parts. First describes HM in the context of neocartography and map design by tackling such issues as denfiition, input data, methods of density determination and generalization, colour schemes, legend construction, and base maps. The second part assesses the range of 17 tools used for creating HM. Tools are divided into non-GIS tools (visualization tools and programming libraries) and GIS applications (desktop and webGIS). GIS desktop software has been selected due to its popularity and wide application. Paper presents an expert assessment of this software with the use of a research questionnaire. The analysis made it possible to develop a division of tools based on their embedding in computer programs and applications and taking into account the types of visualization. It also made it possible to indicate tools that can be used by both professional GIS users (e.g. analysts, cartographers) and the general public, including teachers using HM to visualize geo data for geography lessons. The limitation of the review was the analysis from the expert's point of view. It would be desirable to include novices perspectives in future studies due to the wide demand for visualization.

Efforts on the management of water resources, especially irrigation and drainage, in arid-semiarid areas are extremely important for the sustainability of irrigated agriculture. Groundwater level should be constantly monitored and kept at the desired level in the project which is achieve the expected benefits from investments made for this goal. The research was done in right bank irrigation area which is located in Southeast Turkey, Suruc Plain in 2017. The spatial and temporal fluctuations of the groundwater table depth and groundwater salinity were measured in the course of five-month-periods; from July to October. The results of depth (m) and salinity (µmhos cm-1) of the groundwater observation wells were mapped using geographical information system (GIS). The results showed that groundwater was not found in many observation wells, while groundwater depth reached to a critical threshold level (2 m (risk free for drainage) from July to October in the study area. The groundwater salinity was found to be less than 2250 µmhos cm-1 at the research area. Depending on the research findings, it was noted that there were not any waterlogging, drainage and salinity problems stemming from the rise of groundwater table due to short-term irrigated agriculture in the plain.

The gully erosion is the most serious environmental problem in Agulu-Nanka, Southeastern Nigeria. Present study focused on characterization of geo-environmental factor in the gully affected areas to prevent future problems. The study investigates geotechnical analysis and catchment management of gully erosion in Agulu - Nanka, Anambra State, Nigeria. The major objectives were: to provide geotechnical parameters and data (permeability, liquidity, plasticity, consistency, moisture content and compaction) of the soils available in Agulu Nanka, Anambra State. The method of data collection employed was through field work which involves the use of GPS to capture the coordinates of the gully sites and tape rule to measure the width, depth, and length of the gullies. GIS techniques were used in data analysis. A total of 14 gully sites were coordinated and mapped, the result reveals the gully erosion were dispersed with areas of Nanka/Oko having the highest concentration of gullies. The generation of gully characteristic map reveals that the gullies vary from area to area in relation to their lithology. The characteristic map (in meters) was classified into three parameters with 2.00-6.06 as Low, 6.06-8.89 as Medium, and 8.89-13.77 as High. The gullies with the highest depths were within the coordinates of N6220.9364, E7458.5948; N6228.6836, E7459.4048; N6311.6208, E74333.6612 with 52.96m, 47.32m and 45.18m respectively. The length of the gullies at the concentrated region stretched as far as 4.37km while the gully with the largest width covered a large space of 397.20m. The result indicate the need for incorporation of gully vulnerability, the areas require dire attention to arrest the menace of the erosion threats.

Opis:
W ostatnich latach coraz częściej do kartowania używa się odbiorników GPS. Oprócz odbiorników geodezyjnych, o dużej dokładności, wyodrębnić można odbiorniki klasy GIS charakteryzujące się pracą tylko na częstotliwości L1 w trybie kodowym, umożliwiające jednak wykonanie post-processingu danych w celu zwiększenia dokładności pomiaru. Dokładność pomiaru z post-processingiem maleje wraz ze wzrostem odległości od stacji referencyjnej. Autor na podstawie obserwacji z 50 stacji systemu ASG-EUPOS zbadał tę zależność wykorzystując obserwacje kodowe na częstotliwości L1. Stację LODZ potraktowano jako odbiornik ruchomy, natomiast pozostałe stacje jako referencyjne. Wykonano post-processing w oparciu o każdą stację osobno. Do obliczeń użyto bezpłatnego oprogramowania RTKlib. Wyniki potwierdzają spadek dokładności wraz ze wzrostem odległości, jednak nie jest to zależność liniowa. Generalnie badania dowodzą, że uśredniony błąd w najdalszym miejscu od stacji LODZ, oddalonym o ok. 350 km nie przekroczył 100 cm w poziomie i 170 cm w pionie.
There has been a significant increase in using GPS receivers in mapping during the last few years. Aside from high precision GPS receivers there are also GIS class receivers that work on L1 frequency in the code mode and enable performing post-processing of data. The post-processing accuracy decreases as the distance to the reference station increases. Based on observations from 50 ASG-EUPOS stations the author analyzed this phenomenon using code mode observations on L1 frequency. The LODZ station was considered to be a rover while the rest of stations were treated as reference stations. The post-processing was performed separately for every single station using freeware software RTKlib. The results confirmed the initial assumption: the accuracy decreases as the distances increase without being a linear relationship, though. In general, the survey proves that average error in the furthest spot (350km from LODZ station) is no greater than 100 cm horizontally and 170 cm vertically.

Upsurges of desert locusts can cause heavy economic and agricultural losses and threaten the food security of millions of people over dozens of countries. Therefore, monitoring and spatial delimitation of their habitats are necessary for biological control studies and sampling, especially on large surfaces. This study aimed to assess and map suitable biotopes for desert locusts in southern Algeria, through a GIS tool, by integrating multicriteria analysis (Analytical Hierarchy Process) as a decision-making tool for preventive methods, biological control and research. The result is a resolution map, classified into four different zones according to pixel values. The results revealed that 28.51% of the study area is an unsuitable biotope for desert locusts, 35.92% is a survival biotope, 19.5% is a suitable biotope mainly for breeding and eggs lying and 16.05% is highly suitable for desert locust gregarization and concentration. This study offers a simplified mapping procedure to assess locust habitats for decision-making and studies in large areas.

The aim of the paper is to contrast existing protected areas which are environmentally valuable according to traditional preservation rules with the areas where provision of the selected ecosystem services is the greatest according to the current research standards on ecosystem service hotspot mapping. In order to achieve that we developed the comprehensive method for mapping ecosystem services which could be applied in the national ecosystem assessment process. We selected four ecosystem services, each of which is spatially presented and evaluated using appropriate indicators. The services we consider are global climate regulation, moderation of extreme events, erosion control, and fresh water provision. According to the Common International Classification of Ecosystem Services vol. 4.3 these ES could be divided into two section: provisioning and regulating.
Niezbędna jest poprawa wiedzy na temat ekosystemów i oferowanych przez nie usług w krajach należących do Unii Europejskiej, aby osiągnąć główne cele zapisane w Strategii ochrony różnorodności biologicznej do 2020 roku. Z tego powodu państwa członkowskie, we współpracy z Komisją Europejską, są zobowiązane zidentyfikować i ocenić stan ekosystemów i ich usług. Istnieją różne podejścia do mapowania usług ekosystemów, z których jednym jest analiza hot spot. Jest ona dobrym narzędziem do identyfikacji obszarów, które nie są chronione, lecz są ekologicznie cenne i dostarczają wielu usług ekosystemów. W badaniu przeprowadzono analizę czterech potencjałów usług ekosystemów: globalnej regulacji klimatu, kontroli erozji, moderacji ekstremalnych zjawisk i dostarczania wody pitnej. Większość z punktów hot spot dla wybranych usług ekosystemów województwa dolnośląskiego była zlokalizowana w obrębie obszarów chronionych, zwłaszcza tych objętych ochroną w formie Natura 2000.
