Technical aspects of geothermal energy utilization in Małopolska Region
(2009) Barbacki, Antoni
The paper discusses the technical aspects of geothermal energy utilization in Małopolska and provides a brief description of the technological solutions available to exploit the thermal aquifers typical of this region, for heating and recreation. It includes some technological solutions for the recovery and management of heat in this area, together with examples of how heat pumps and combined heat and power units are used in Poland.
Analysis of legal regulations concerning the division of a building lot, with a building on it, in view of geodesic and building regulations
(2009) Buśko, Małgorzata; Przewięźlikowska, Anna
Przedmiotem artykułu jest analiza przepisów prawnych związanych z podziałem nieruchomości zabudowanej budynkiem w aspekcie występujących w nich rozbieżności. Szczególna uwaga została poświęcona definicjom nieruchomości, działki ewidencyjnej, budynku i obiektu budowlanego. Przytoczone przepisy prawne, normy techniczne i standardy geodezyjne skłaniają do wyprowadzenia wniosku, że zapisy dotyczące podziałów nieruchomości są nieprecyzyjne, niespójne, a niejednokrotnie sprzeczne.
Preliminary study of the possibility to use a mobile measurement rosette for testing horizontal distortions
(2009) Ćwiąkała, Paweł; Skulich, Mikołaj; Frukacz, Mariusz
The structure and characteristics of a measuring system referred to as the 'mobile measurement rosette' have been presented and the subject of the study using the rosette has been discussed. The system in question allows measurement of horizontal distortion of land subjected to the impacts of mining exploitation. It has to be stressed that horizontal distortions of land in mining areas are among the major indices of deformation describing the impact of mining exploitation on the surface and building structures there on, and studies are still underway as to the problem of continuous measurement and interpretation of results obtained. One of the keys to proper operation of the system is to consider the effect of thermal expansion of the rosette material. The results of laboratory and field tests presented here in indicate the possibility to use the system for measurement of horizontal distortion in areas affected by mining exploitation.
Application of Landsat imagery based vegetation indices to imperviousness index mapping
(2009) Drzewiecki, Wojciech; Osak, Agnieszka
W publikacji przedstawiono zastosowanie teledetekcyjnej metody opartej na wskaźnikach wegetacji do sporządzania map współczynnika nieprzepuszczalności. Mapy te przedstawiają w odniesieniu do każdego piksela obrazu satelitarnego procentowy udział powierzchni o charakterze nieprzepuszczalnym, takich jak np. dachy budynków, drogi asfaltowe, parkingi itp. Wykorzystanie obrazów satelitarnych Landsat TM pozwala na uzyskanie porównywalnych map dla okresu od połowy lat 80. XX. wieku do chwili obecnej. Opracowanie wykonano dla obszaru Krakowa w roku 1996. Uzyskana dokładność oszacowania współczynnika nieprzepuszczalności wyniosła 20 procent.
Photogrammetric and laser scanning data integration
(2009) Mikrut, Sławomir
The subject of research included integration of laser scanning data with photogrammetric data, and an attempt at identifying the 'bottlenecks' in available technologies, and offering proposals for solving them. The research was conducted based on an exemplary facility, located in the Ethnographic Park of the Village Museum at Tokarnia, Poland. One of the museum exhibits, a windmill, was utilised as a test field, as there was a good access to it, as well as because of certain, expected complications related to processing parts of the windmill, such as e.g. penthouses. The research employed a Z-F Zoller-Fröhlich, model IMAGER 5006 laser scanner, a Rollei 6008 digital photogrammetric camera, a TCR 405 POWER prismless total station, RealWorks Survey Advanced, Photomodeler and Dephos software, as well as own algorithms, collected in the authorial feature extraction software (FES). In this paper, a certain pattern of integration of photogrammetric data with a point cloud was proposed. It was based on that pattern, that the exemplary project was developed. Also, an attempt was made at improving the quality of integration though the use of algorithms of sub-pixel edging of data, both in the digital image, and in the point cloud. The so-developed methodology is useful, not only when surveying historic buildings and structures. It can also be applied in the course of works related to the surveys of buildings, industrial facilities, boring towers, etc. Also known are non-typical applications of the method, which include e.g. the survey of a post- accident condition conducted by the police on the accident spot, as well as a whole array of applications of the air scanning, which (due to their extensive scope) have not been included in this paper. The completed experiments as well as data from the literature on the subject make it possible to declare that the results of the use of photogrammetry combined with laser scanning are promising. This is a quick and an efficient technology. Owing to scanning, we can obtain a very large amount of data, while photogrammetry provides radiometric data of a high quality. That combination seems to be indispensable in near future, and one may expect it will quickly be developing.
