Opis:: This study discusses cartographic presentation options for determining the worth of undeveloped land zoned for single-family housing development. Three spatial interpolation methods have been analyzed: inverse distance weighting, local polynomial interpolation and ordinary kriging. The obtained results indicate that the above methods can be applied to develop cartographic maps illustrating land worth where value at a given point in space is determined based on the prices of property in the immediate vicinity, thus satisfying the location-based similarity condition. The study relied on property transactions registered in Olsztyn in 2007–2009.
W pracy przedstawiono możliwości kartograficznej prezentacji cenności gruntów niezabudowanych przeznaczonych pod zabudowę jednorodzinną. Przeanalizowano trzy metody interpolacji przestrzennej: średniej ruchomej ważonej odległością, interpolacji wielomianowej oraz krigingu zwyczajnego. Wykazano, że dzięki zastosowaniu tych metod możliwe jest opracowanie kartograficzne w postaci mapy cennosci gruntów, gdzie cenność w danym punkcie przestrzeni określona jest z wykorzystaniem informacji o cenach nieruchomości w najbliższym otoczeniu, a więc spełniających warunek podobieństwa lokalizacji. Badania przeprowadzono z wykorzystaniem danych o transakcjach nieruchomościami gruntowymi, które miały miejsce w latach 2007–2009 na terenie Olsztyna.

Opis:: In Indonesia, there are underground mines for mineral metal such copper (Cu) and gold (Au), built by tunneling towards the mineral location. The purpose of this study was to determine the mapping a concentration of diesel particulate matter (DPM) and assess the impact on health by severity measurement of airflow obstruction of the miners experiencing chronic obstructive pulmonary disease (COPD). The data of DPM were measured with NIOSH method no. 5040 and applied a geostatistical method in mapping concentration at the area of underground mining. A spirometric measurement was conducted to diagnose COPD that is done to the 314 miners. The results showed that the concentrations exceeding the permissible exposure limit (PEL) and spirometric measurement were found for 26 miners (8.3%) who experience COPD (post bronchodilator <0.70). The severity measurement of airflow obstruction of the miners experiencing COPD, severity of airflow limitation for moderate (GOLD 2) was obtained for 14 miners (54%); severe (GOLD 3) for 10 miners (38%) and very severe (GOLD 4) for 2 miners (8%). It can be concluded that the amount of DPM exposure against the severity of airflow limitation with COPD by 0.03, in which the other factors also affect the severity.

Opis:: Understanding the spatial variability of soil organic matter (SOM) is critical for studying and assessing soil fertility and quality. This knowledge is important for soil management, which results in high crop yields at a reduced cost of crop production and helps to protect the environment. The benefits of an accurate interpolation of SOM spatial distribution are well known at the agricultural, economic, and ecological levels. It has been conducted this study for comparing and analyze different spatial interpolation methods to evaluate the spatial distribution of SOM in Sidi Bennour District, which is a semi-arid area in the irrigated scheme of the Doukkala Plain, Morocco. For conding this study, it was collected 368 representative soil samples at a depth of 0–30 cm. A portable global positioning system was used to obtain the location coordinates of soil sampling sites. The SOM spatial distribution was performed using four interpolation methods: inverse distance weighted and local polynomial interpolation as deterministic methods, and ordinary kriging and empirical Bayesian kriging as geostatistical methods. High SOM levels were concentrated in vertisols, and low SOM levels were observed in immature soils. The average SOM value was 1.346%, with moderate to high variability (CV = 35.720%). A low SOM concentration indicates a continuous possibility of soil degradation in the future. Ordinary kriging yielded better results than the other interpolation methods (RMSE = 0.395) with a semivariogram fitted by an exponential model, followed by inverse distance weighted (RMSE = 0.397), empirical Bayesian kriging (RMSE = 0.400), and local polynomial interpolation (RMSE = 0.412). Soil genetics and the strong influence of human activity are the major sources of SOM spatial dependence, which is moderate to low. Low SOM content levels (< 1.15%) were present in the southwestern and eastern parts of the digital map. This situation calls for the implementation of specific soil recovery measures.
