Opis:: Praca podejmuje zagadnienia związane z możliwościami, jakie daje wykorzystanie systemów informacji przestrzennej (z ang. GIS - Geographic Information Systems) w rolnictwie, zarówno w ujęciu mikro, jak i makro gospodarczym. Połączenie informacji dotyczących szeroko rozumianej produkcji rolnej z konkretną sytuacją przestrzenną daje praktycznie nieograniczone możliwości analityczne, służące optymalizacji cyklu wytwórczego, łącznie z etapem dystrybucji płodów rolnych. Dzięki temu otrzymujemy narzędzie wpływające na poprawę jakości i efektywności pracy, a co za tym idzie maksymalizację dochodów. Dodatkowo autorzy pracy zwracają uwagę na uniwersalność metod stosowanych w ramach rozwiązań GIS, dzięki czemu mogą z niej korzystać zarówno organy centralne, odpowiadające za realizację polityki rolnej Państwa, jak i indywidualni producenci rolni.
The paper takes up issues related to possibilities resulting from the use of spatial information systems (GIS - Geographic Information Systems) in agriculture, both from micro- and macroeconomic perspective. Linking of information concerning widely understood agricultural production with specific spatial situation gives practically unlimited analytical capabilities, used to optimize manufacturing cycle, including farm produce distribution stage. Owing to this, we obtain a tool that improves quality and efficiency of work, and consequently guarantees income maximisation. Additionally, the authors of this paper draw attention to versatility of methods employed as part of GIS solutions. This makes them useful both for central authorities responsible for implementation of the State agricultural policy, and individual agricultural manufacturers.

Opis:: Municipal solid waste collection points (MSWCPs) are places where residents of municipalities can leave their waste free of charge. MSWCPs should operate in every municipality in Poland. The Geographic Information System (GIS) and analytical hierarchy process (AHP) were used in conjunction as tools to determine potential locations of MSWCPs. Due to possible social conflicts related to the location of MSWCPs, three variants of buffer zones for a residential area were adopted. As a result of the spatial analysis carried out using the GIS software, 247 potential locations were identified in variant no. 1 (which accounted for 7.1% of commune area), 167 for variant no. 2 (6.3% of commune area), and 88 for variant no. 3 (3.8% of commune area). The most favourable locations for MSWCPs were determined using the AHP method with additional criteria for which weights were calculated as follows: the area of a designated plot (0.045), actual designation of a plot in the local spatial development plan (0.397), distance from the centre of the village (0.096) and the commune (0.231), and population density of a village (0.231). The highest weights (over 50%) in the AHP analysis were obtained for 12 locations in variant no. 3, two of which had an area over 3 ha. The adopted methodology enabled to identify quasi-optimal solutions for MSWCP locations in the analysed rural commune. This research has the potential to influence future waste management policies by assisting stakeholders In the MSWCP location.

Opis:: Soil erosion is an important factor that should be considered when planning renewable natural resource projects, effects of which can be measured by modelling techniques. Therefore, disintegration models determine soil loss intensity and support soil conservation practices. This study estimates soil loss rates by water erosion using the Erosion Potential Method (EPM) in the Kebir Rhumel Watershed located in Northeast Algeria. The area is north to south sub-humid to semi-arid, receives irregular rainfall, and has steep slopes and low vegetation cover which makes it very vulnerable to erosion. The main factors in the EPM (soil erodibility, soil protection, slope, temperature, and rainfall) were evaluated using the Geographical Information System (GIS) and data provided by remote sensing technologies. The erosion intensity coefficient Z was 0.60, which indicates medium erosion intensity. While the results showed the average annual soil erosion of 17.92 Mg∙ha-1∙y -1, maximum and minimum losses are 190.50 Mg∙ha-1∙y-1 and 0.21 Mg∙ha-1∙y-1, respectively. The EPM model shows satisfactory results compared to some studies done in the basin, where the obtained results can be used for more appropriate management of land and water resources, sustainable planning, and environmental protection.

Tytuł:: Using GIS to obtain Celestial fix under the framework of an ECDIS System

Opis:: This study proposes a simple method for obtaining a celestial fix, developed within a Geographic Information System (GIS) under the framework of an ECDIS system. The underlying principle is dependent on the most fundamental theory in celestial navigation; the circle of position (COP) of the celestial bodies is plotted to find the fix. Through the spatial data processing, analysis, and visualization capabilities available in GIS, a celestial fix may be obtained directly from plotting. This eliminates the limitations associated with finding the fix manually using a paper map, but also avoids the cumbersome work and inaccuracy of the traditional Intercept Method (IM) or the complicated, and often obscured, computation involved in numerical methods. The proposed method is simple and accurate, and it applies to problems involving two or more celestial bodies and high-altitude observations. It provides a reference for the development of a celestial positioning module in an ECDIS system, and could also be integrated into an educational program on electronic celestial navigation.

Opis:: Scarcity of freshwater is one of the major issues which hinders nourishment in large portion of the countries like Ethiopia. The communities in the Dawe River watershed are facing acute water shortage where water harvesting is vital means of survival. The purpose of this study was to identify optimal water harvesting areas by considering socioeconomic and biophysical factors. This was performed through the integration of soil and water assessment tool (SWAT) model, remote sensing (RS) and Geographic Information System (GIS) technique based on multi-criteria evaluation (MCE). The parameters used for the selection of optimal sites for rainwater harvesting were surface runoff, soil texture, land use land cover, slope gradient and stakeholders’ priority. Rainfall data was acquired from the neighbouring weather stations while information about the soil was attained from laboratory analysis using pipette method. Runoff depth was estimated using SWAT model. The statistical performance of the model in estimating the runoff was revealed with coefficient of determination (R2) of 0.81 and Nash–Sutcliffe Efficiency (NSE) of 0.76 for monthly calibration and R2 of 0.79 and NSE of 0.72 for monthly validation periods. The result implied that there's adequate runoff water to be conserved. Combination of hydrological model with GIS and RS was found to be a vital tool in estimating rainfall runoff and mapping suitable water harvest home sites.
