Просторна интерполација падавина у зависности од надморске висине у сливу Скрапежа

Author(s): Dragoljub Štrbac,Jelena Kovačević-Majkić / Language(s): Serbian Issue: 1/2008

In order to make an adequate basic dataset for a subsequent hydrological research, the study of interpolation of precipitation values from measurement stations (points) to large areas (areas) was done. Among many statistical interpolation methods that estimate precipitation values in unsampled areas (where there are no measurements or they are sparse), spatial interpolation method which includes relief (elevation) was chosen for the study. Inclusion of elevation parameter was done in order to minimize the extent of interpolation errors. Research was done in the catchments area of the Srkapež River (Western Serbia). Precipitation data were collected from 19 measurement stations for the period from 1961 to 2000. The reduction method was used for filling the missing data in the data set. The best framework for managing spatial (georeferred) data is Geographical Information System, enabling easier calculation and improved precision. Therefore, raster GIS was used for spatial interpolation of precipitation and for calculating mean annual precipitation value. Concerning the fact that the observed area is a mountainous region, where precipitation may change over short spatial scales, a DEM with a grid resolution of 100 m was used.

Regioninės archeologijos link: archeologinių tyrimų geoduomenų bazė

Author(s): Rokas Vengalis / Language(s): Lithuanian Issue: 43/2017

The article discusses the need for comprehensive regional geodatabases in Lithuanian archaeology. It asserts that the existing databases, which are based on the idea of archaeological sites, are insufficient for the analysis of many of the questions raised by regional and landscape archaeology and that it is therefore necessary to support an off-site conception. Because such database should be more complex and composed of many separate parts, the article presents only one of them, the part devoted to archaeological research conducted in one region (Kernavė in eastern Lithuania). The article discusses its structure and highlights the problems that arise in classifying data with very differing information levels. This database also does an excellent job of showing the representation level of the archaeological map of Lithuania: the scale of all of the investigations that have been conducted up until now, the unevenness of the territorial distribution, and the diversity of the applied methods. After mapping all of the conducted investigations, it was discovered that they have been concentrated in only several intensively investigated locations while large regions which are essentially unknown to archaeological science to this day exist around them.

The use of Terrestrial Laser Scanning for the purposes of preparing technical documentation in BIM technology

Author(s): Łukasz Uchański,Krzysztof Karsznia / Language(s): English Issue: 3/2018

Building Information Modelling (BIM) is becoming an increasingly popular solution used both for investment and for reverse engineering aimed at restoring of the original documentation of existing facilities. The reconstruction of an object including its full design properties in an interactive 3D environment makes it possible to carry out structural (including SMH – structural health monitoring) and strength analyses, as well as to provide the effi cient facility management (setting out essential parameters and conducting necessary repairs). This paper aims to assess the laser scanning performed by using an advanced pulse data-capturing device for the development of complex BIM documentation in the Water Centre Laboratory of Warsaw University of Life Sciences – SGGW. Obtained point clouds have been used to build the model for the needs of reverse engineering. Moreover, the authors evaluated the possibility of using a particular type of laser scanner to develop and update complex BIM documentation in the process of facility management.

TUZGÖLÜ FAYI ve CİVARININ DEPREM RİSKİ

Author(s): Tekin Yeken,Ahmet Cem Yoğurtçuoğlu / Language(s): Turkish Issue: 40/2018

Since the 1960s, there have been important instrumental developments in seismology. Intensive studies are carried out to learn the tectonic earthquakes and their seismic risks. The information obtained from these studies has been important in the development of plate tectonics theory and other plate models. Elastic deformation energy has accumulated in the lithosphere as a result of the long-lasting movements between the plates. The purpose of seismological studies was to determine the faulting of the power system and the geometry of the force system. In this study, it is aimed to determine a time period where an earthquake with destructive and destructive magnitude can be repeated in the region by statistical calculations. This is also an important element of the earthquake risk concept. Faults controlling the seismic activity in the region play an important role in their seismic movements. The aim of the study is to analyze seismic risk in the fault zone and its vicinity by using TFZ seismic activity data. All earthquake data from the instrumental period to the current records were taken. According to the results, although the earthquake in the region is not common, the magnitude of the earthquakes of M≥5 magnitude has been determined. It is expected that the tectonic development of the region will contribute to the determination of deformations and tectonic modeling.

Method of Topographic Inventarization and GPS Technology in Geospatial Modeling

Author(s): Boban Milojković,Jasmina Jovanović / Language(s): English Issue: 2/2018

By the use of digital cartographic visualization, a wide range of relevant data can be systematically integrated, presented and analyzed. In particular, this refers to the connection between thematic and topographic maps and their application in the study of the environment. The specific purpose of the map implies that in certain situations there is no clear difference between the thematic and topographic maps, that is, there is no clear boundary between the thematic and the topographic content of the representation. The paper points to the importance of modeling geoenvironmental data (topographic and thematic) for different scientific and practical research needs. Bearing in mind the global size of orienteering, the heterogeneity of the geoenvironment in which competitions and ways of orientation are organized, it is necessary to standardize this topic at the international level. The conducted experiment of cartographic modeling in the orienteering function has examined the possibilities of application of topographic inventory methods of geoenvironment for this purpose, the importance of using GPS devices for collecting geoenvironmental data and CAD software for cartographic visualization of the issues in question.

Stocktaking methods of facilities in a state of ruin

Author(s): Katarzyna Drobek,Bartosz Szostak,Wojciech Królikowski / Language(s): English Issue: 4/2018

The stocktaking is the basic form of presenting and protecting the object of the historic ruin. It also allows to monitor the behavior state and the degradation progress of an object. Objects in ruin are very specifi c because they usually do not have elements typical for an existing building. This means that in the case of ruins, methods of stocktaking taken in the same way as in the case of traditional facilities will be insuffi cient. Elements of objects in ruin often have complicated and diverse geometry, diffi cult and not completely secure access to all elements. The article presents methods that can be helpful in the stocktaking of such objects. Each method describes the necessary equipment and instruments, the method of taking measurements, accuracy, advantages, and limitations. The paper also presents examples of application for selected methods.

The analysis of spatial and functional modifi cations of the palace in Krzesimów in Mełgiew commune aiming at adaptation of the building to the requirements of a social welfare home

Author(s): Karol Krupa,Piotr Gleń / Language(s): English Issue: 4/2018

The palace in Krzesimów was built in the classicist style at the beginning of 19th century. The building is the part of the palace-park complex entered into the register of monuments because of its historical, aesthetical and landscape values. From 1970s, it is the headquarters of a social welfare home. Over the years, this function enforced many changes in the functional layout of the building to adapt it to the needs of people with various types and levels of disability. Despite many minor renovations and modifi cations, the palace didn’t undergo complete overhaul, which would greatly improve the technical condition of the original fabric. This aim of article is to analyse introduced functional changes, which were supposed to facilitate the use of the building by the handicapped, and to consider what actions must be undertaken in order to improve its technical condition. The authors of the paper underline the need to start renovation works on the basis of the archive documentation, as well as conducted survey and research of its current technical condition.

Modyfikacja składu granulometrycznego i właściwości geotechnicznych gruntu niespoistego za pomocą dodatku pyłu

Author(s): Agnieszka Lal / Language(s): Polish Issue: 4/2018

Frequent issue in the practice of soil engineering is the fi ll soil compactibility. The uniformity coeffi cient Cu of the Sand, Sand-Gravel and Gravel, that are the most common fi ll soil, is relatively low and usually is in the range of 2.5 – 4.0. These values allow to describe Sand, Sand-Gravel and Gravel as uniformly graded. The aim of the paper was to determine the impact of modifi cation of the grain size distribution of the non-cohesive soil – Medium Sand (MSa) on its compactibility. The loess silt, sampled in the territory of the Lublin city was used to modifi ed the Sand particle size distribution. Loess silt cover the considerable area of the Lublin, frequently in the surface zone. This ensures that loess silt could be reckoned as the easily accessible material. Laboratory tests were conducted on prepared samples of three kinds of soils – Medium Sand, Medium Sand combined with loess silt in the volume proportion of 1:1 and Medium Sand combined with loess silt in the volume proportion of 2:1. There were sieve and hydrometer analysis performed to quantify the percent fi ner by weight of grain size of prepared samples of the soils. As the result of grain size analysis particle size distribution curves were obtained. Estimated effective size D10 and D60 were used to determine the uniformity coeffi cient. The value of coeffi cient Cu for the Medium Sand was equal to 1.71 and it rose up to 21.8 (in case of Medium Sand combined with loess silt in the volume proportion of 1:1) and 13.3 (for the Medium Sand combined with loess silt in the volume proportion of 2:1). Obtained values suggest, that modifi cation of Sand grain size distribution with use of loess silt allows to classify received probes as soils with high compactibility. In order to prove this thesis Proctor tests were conducted. There were the same three kinds of the soil tested according to procedure I. Results indicate that Medium Sand with natural grain size distribution reached the maximum dry density of 1.751 g/cm3 at the optimum water content of 11.96 %. The maximum dry density of Medium Sand combined with loess silt in the volume proportion of 2:1 and 1:1 reached accordingly 2.079 and 2.076 g/cm3 at the optimum water content of about 7%. During Proctor test, there were plasticity of Medium Sand combined with loess silt in the volume proportion of 1:1 remarked, for the samples of water content greater than 14.25%. Increased plasticity prevents compaction of the examined soil with humidity above 14.25%, due to the deformations and cohesion. As the results of conducted laboratory tests, there were ascertained that modifi cation of the grain size distribution of Medium Sand with loess silt with volume proportion of 2:1 allows to reached the maximum compactibility. Therefore, combination of the Sand and relatively easily accessible loess could be used in soil engineering as the fi ll soil.

Author(s): Radosław Cellmer / Language(s): Polish Issue: 1/2012

One of the most important factors influencing price and its effect on the value of real estate is location, which can be considered on both global and local scales. The result is that prices in a given location should be similar and they should show spatial auto-correlation. This paper deals with the essence of spatial autocorrelation and introduces a methodology of measuring spatial dependences. The results of the research concern housing prices in the vicinity of Olsztyn. For research purposes, global and local Morans and Getis-Ord indexes were used along with an analysis of semi-variograms. In this way, both the spatial autocorrelation and spatial differentiation of dependencies between housing prices were determined.

Analiza dokładności określenia jednostkowej wartości nieruchomości metod korygowania ceny średniej

Author(s): Edward Sawiłow / Language(s): Polish Issue: 1-2/2006

The dissertation presents the basic rules of estimating the real estate using the method of correcting the average price. The pattern for estimating the real estate value by the method of correcting the average price into the lineal function of many variables has been transformed. The analysis of the precision of the method in relation to the precision achieved due to the lineal model of regression of multiple variables has been shown. The results confirm the smaller accuracy of estimating the real estate value using the method of correcting the average price in relation to the results from the model of linear regression of variables.

Author(s): Zigmas Kairaitis,Aušra Birgelytė / Language(s): Lithuanian Issue: -/2014

The article analyses the geographic world-view of Lithuanian geographer, traveller, Associate Professor Rimantas Krupickas (1945–2009). The scientific theories of the second half of the 20th century (general systems theories, theories of synergetics, chaos and nonlinear dynamics), principles of systematic thinking and the significance of the rational and irrational origin on the scientific cognition are discussed. All of this is related to the influence of the post-modern science on the scientific attitudes of the Professor. The postulates of the systems theory and systematic thinking that mostly conditioned the Professor’s attitude towards the geography are discussed in more detail. It is reflected in one of his main works – the monograph Systems Theory and Geography (2010). It is accentuated that the Professor associated systems theory and systematic thinking with the perspective of geography as the science.
