Description

The dissertation presents a research on harmonisation of spatial information applied in digital cartography, based on them improved methodology, detail methods for identification and evaluation the changes in features of spatial data.

The main aim of the thesis is to improve the harmonisation process for spatial data used in digital cartography and data modelling.

The thesis comprises an introduction, three chapters, general conclusions, list of references, list of scientific publications by the author on the subject of the dissertation and annexes.

The introduction provides the background to the research problem, defines the relevance of the problem, formulates aims and objectives, describes scientific novelty of the thesis, presents defended statements of the dissertation, author’s publications and conference presentations, and describes the structure of the dissertation.

The first chapter analyses scientific literature on harmonisation of spatial data and its abilities in the environment of spatial data infrastructure. Moreover, it presents an overview of automated generalisation methods for spatial data and identification principles of changes in spatial data. Then, it formulates problematic issues of the research and objectives to achieve the aim of the thesis.

The second chapter presents the improved methodology for harmonisation of spatial data. It further presents generalisation algorithms for resolving tasks of the specific generalisation tasks. Furthermore, the chapter centres on changes in spatial data, which may affect automatic harmonisation of spatial data when incremental generalisation is involved in digital cartography. Finally, it introduces identification and evaluation methods for changes in spatial data.

The third chapter is dedicated to the implementation of the methodology for the harmonisation of spatial data relating to (geo)referential spatial data sets at the scales 1:10000 and 1:50000. The results of the harmonisation process are presented.

The subject of the dissertation was presented in eight scientific articles, one of which was published in periodicals referenced in international data bases; two in publications of international conferences; four in other data bases; and one in the proceedings of a national conference; besides, there were made nine presentations at conferences in Lithuania and abroad.
