Demographic data are commonly represented by using a choropleth map, which aggregates the data to arbitrary areal units, causing inaccuracies associated with spatial analysis and distribution. In contrast, dasymetric mapping takes quantitative areal data and attempts to show the underlying statistical surface by breaking up the areal units into zones of relative homogeneity. This thesis applies...

The two ways of theoretical determination and modeling of the elastic properties of geological or modern technological materials are discussed. Such samples are characterized by a whole string of parameters or distributions (volume parts of the phases, sizes, shapes of the grains, or voids and their orientations etc.). The direct way uses first principles, averaging the strain field calculated ...

The use of digital information in geological fields is becoming very important. Thus, informatization in geological surveys should not stagnate as a result of the level of data accumulation. The integration and sharing of distributed, multi-source, heterogeneous geological information is an open problem in geological domains. Applications and services use geological spatial data with many featu...

Stochastic simulation of facies or geologic units is important before the assignment of continuous rock properties. Sequential indicator simulation (SIS) remains a reasonable approach when there are no clear genetic shapes that could be put into object-based modeling. Constraining SIS to soft secondary data coming from geological interpretation or geophysical measurements is important. There ar...

The paper presents an analysis of the LiDAR-based landslide inventory for area near Samobor, in northwestern Croatia with two main objectives: i) to define geological units (obtained from Basic Geological Map Croatia) most susceptible landslides, and ii) analyse limitations its applicability susceptibility map design. Within study 63.8 km2, 874 polygons were manually outlined, covering 2.15 km2...

Generally, alluvial basins of arid and semiarid zones are the places with excessive groundwater withdrawal, and also they have a high potential for land subsidence. Excessive groundwater withdrawals have caused severe land subsidence in Tehran, Iran. At present, the maximum land subsidence rate is 36 cm/year, covering an area of nearly 530 km2. In the 2000s, as a result of economic and populati...

The Dehaj area, located in the southern part of the Urumieh-Dokhtar magmatic belt, is a well-endowed terrain hosting a number of world-class porphyry copper deposits. These deposits are all hosted in an acidic to intermediate volcano-plutonic sequence greatly affected by various types of the hydrothermal alterations, whether argillic, phyllic or propylitic. Although there are a handful of hithe...

Reservoir characterization This paper gives an overview of the activities in geostatistics for the Petroleum industry in the domain of reservoir characterization. This description has been simplified in order to emphasize the original techniques involved. The main steps of a study consist in successively building: • the reservoir architecture where the geometry of the units is established, • th...

Castanea sativa Mill. is thought to be originated from Turkey. It is an important deciduous angiosperm with edible fruits and valuable wood. It has a wide distribution from east Black sea to Marmara and Aegean Regions. Because of its wide distribution, C. sativa grows on different ecological, geological, climatic and edaphic condition and these results in different associations with different c...
