Przedmiotem badań niniejszej rozprawy jest opracowanie zasad konwersji dwuwymiarowych obiektów Bazy Danych Topograficznych (TBD) do postaci 3D oraz sposobów jej graficznej prezentacji w Internecie. Podczas prac badawczych nad tym zagadnieniem stworzono model konceptualny trójwymiarowej wielorozdzielczej bazy danych topograficznych (TBD3D), który ma stanowić dodatkowy moduł TBD umożliwiający wizualizację 3D oraz analizy przestrzenne. Opracowano nową systematykę obiektów TBD3D na trzech poziomach szczegółowości oraz katalog symboli 3D. Określono formę i szczegółowość przedstawiania poszczególnych obiektów, jak również warunki jakie powinien spełniać system zarządzania TBD3D oraz jakim zasadom powinna podlegać wizualizacja 3D. Zgodnie z proponowaną koncepcją TBD3D dla poszczególnych poziomów szczegółowości, po uprzedniej analizie dokładności i przydatności poszczególnych metod, wskazano odpowiednie źródła danych (m.in. dane fotogrametryczne i lidarowe) wraz z algorytmami działań wykorzystujących i rozbudowujących funkcjonalność programów fotogrametrycznych i CAD. Następnie, stosując się do proponowanych w ramach niniejszej pracy zasad pozyskiwania danych 3D, stworzono przykładowe bazy TBD3D dla wybranego fragmentu miasta. Na koniec opracowano nowy schemat GML3 (TBD3DGML) służący do przesyłania danych TBD3D pomiędzy różnymi systemami geoinformacyjnymi oraz udostępniania ich przez Internet.

This dissertation presents the main concept and execution of geoinformatic subsystem, that will be used to support real estate market analysis and real estate appraisal. Attributes’ inputting into the database takes place by means of special designed dialog windows. Values of particular attributes’ are calculated on the basis of five degrees attributes’ scales. This work presents also the ‘subbase creator’ algorithm which was worked out by the author. The main stage of this algorithm is the calculation of the price creative indicator for each real estate, using their attributes’ values. The subsystem can make more efficient real estate market analysis and real estate appraisal process thanks to this implemented algorithm. Geographical Information System software was used for realization this project, therefore the subbase, chosen in this way, can be visualized on the map. The geoinformatic subsystem will be used for the un-built real estates and living premises.

Thesis constitutes an attempt to develop method of using mobile agent system for searching and acqire imagery data, from sparse database over Internet, for the purpose of photogrammetry. It includes description of current network protocols and methods of sharing geodata used so far. Furthermore aplied mobile agent system and set of complementary written programs were presented, as well as photogrammetry basics for algorighms of those programs. Last part of thesis was dedicated to critilcal evaluation of correctness, efficiency and uniqueness of designed method. All stages of project were made with open source software. Research has proved that agent system in connection with other network transmission methods can be sucessfully used as means to obtain imagery data. Sparse database may contain aerial photos, but due to modular architecture of system its easy to expand it to support other kind of images. It's been estabilished, that thanks to designed method, time of aquiring data has reduced and realibility of data access has improved, when compared to traditional methods.

System geodezyjnego i diagnostycznego monitorowania stanu infrastruktury transportu szynowego
(Data obrony: 2012) Kampczyk, Arkadiusz
Wydział Geodezji Górniczej i Inżynierii Środowiska
The doctoral thesis concerns a geodetic and diagnostic system for monitoring of state of rail transport infrastructure. Railways are the most important representative of rail transport in Poland. The thesis contains an analysis and assessment with conclusions of both the legal state and value of already collected data, and these of their features, which should necessarily be included in the monitoring system. The system is equipped with a common information flow between regional databases of the PKP PLK S.A. company, and its central database. The doctoral thesis sets forth a management strategy for the Company. The author's invention included in the thesis pertains to „a method of identification of rail transport infrastructure elements", Polish Patent Office submission number RP P - 393 050, while pertinent data collection method has signature CTT/251/2010 of the Technology Transfer Centre of the AGH-University of Science and Technology in Cracow, Poland. Within the monitoring system it is proposed to divide railway lines into so called measurement sections, which in turn should be divided into measurement sectors maximum 4 km long. Beginning and end of each measurement sector should be marked with an identifier invented by the Author.

Wykorzystanie wysokorozdzielczych obrazów radarowych dla potrzeb tworzenia map pokrycia obszarów miejskich

The subject of the presented work is analysis and evaluation of usefulness of high resolution radar data in the context of creating land cover maps for urban areas and checking the suitability of the proposed method of classification. The potential of mapping and interpretation of high resolution TerraSAR-X data was examined and an optimal way of processing this data from the point of view of obtaining information about land use and land cover for urban areas was presented. The attempt of developing guidelines for the selection of appropriate data set was also made to carry out the correct classification and suitable analysis. For this purpose, data sets of six, single-polarized TerraSAR-X images were analyzed in detail. The images acquired with different parameters and from different types of orbits (descending and ascending), for an area of Cracow were used. On their basis, an automatic classification scheme of high resolution radar images was developed, in objectoriented approach using parametric method, based on a hierarchical database decision rules. Additionally, benefits from an integration of radar and optical data, in order to increase separation chance of land cover elements were checked.

Estimation of exterior orientation parameters (EOP) of images is the fundamental task of photogrammetry. Currently the direct approaches to EOP determination, implemented primarily in mobile mapping system platforms, are preferred. The determination of EOP using measurements of different kind needs the proper integration algorithm. In this work the algorithm designed for integration of photogrammetric, inertial and GPS observations in portable low-cost photogrammetric system is proposed. The system consists of SLR camera, MEMS attitude and heading reference system (AHRS) and GPS set. The calibration of the system was carried out .The two-step algorithm of observation integration was proposed. In the first step the inertial and magnetic measurements are integrated using the AHRS Kalman filter. The exterior orientation parameters of images are calculated using the system calibration parameters. In the second step the combined bundle adjustment with observed EOP is calculated. As a result the estimated EOP are obtained. The performance of proposed algorithm under various network configuration was analyzed in the context of accuracy, redundancy and reliability. Besides, the inclusion of geometric constrains like measured distances, vertically and horizontality of tie lines was examined. The obtained accuracies satisfy the demands of most photogrammetric applications like 3D building modeling.
