data integration

The aim of this article is to present the first model in Poland of contemporary relative vertical movements of the Earth's crust, based on the integration of vertical movements determined from three sources: GNSS measurements (ASG-EUPOS), permanent PsInSAR scatterers from EGMS products, and double precise levelling measurements. Due to differences in the temporal and spatial resolution of the data, it was necessary to develop a consistent integration methodology.

The article describes the peculiarities of the tourism activities information support, describes the role of tourism data consolidation as the optimal integration means of tourism data. The general scheme of tourism documentation formation based on the gaps filling is suggested.

In the paper the method of integrated processing of heterogeneous information resources web-systems is described. This method is based on the model of data description as a coherent combination of data values, rules of data representation, interpretation rules and data structure. The method involves decomposition of general process into subprocesses of data values integration, data syntax integration, semantics and structure integration. The advantage of this approach is that the integration process can be performed at data metascheme level.
