Release: 2016-2 (14)
Keywords: data processing, wavelet transform, shearlet transform, spectral decomposition, morphological analysis
Annotation: We propose a new approach for processing spatial data — the morphological analysis of linear and non-linear structures in conjunction with a spectral decomposition based on the wavelet and shearlet transformations applied to the data about natural disasters
An algorithm for modelling the surface of the terrain
Page:192-195
Release: 2016-2 (14)
Keywords: vector map, polish format, interpolation spline
Annotation: The paper presents a computational algorithm for constructing the surface of the terrain ac-cording to the data at vector maps in Polish format. The input data is a set of contours. Using interpolation splines the grid function of altitude are built based on this data
Application of multisets for solving the practical problems
Page:196-202
Release: 2016-2 (14)
Keywords: multisets, group multi-criteria decision-making, decision-making
Annotation: The paper describes the methods for solving the problem of group multi-criteria decision-making that allow to process different forms of individual preferences and based on the use of multisets. Examples of solving practical problems by using the methods are described
Development of GIS-applications based on geoportal technologies
Page:202-209
Release: 2016-2 (14)
Keywords: web GIS, Internet GIS, web mapping, geoportal, spatial data, content management system, CMS, web mapping services, spatial metadata catalog, WMS service
Annotation: This paper discusses software tools and technologies for development of the applied web-based software systems focused on processing and presentation of geospatial data. The proposed solution is a specialized content management system for website, which takes into account the specificity of GIS web applications
Formal definition of multidimensional analytical indicators calculation as a sequence of OLAP-cube operations
Page:209-215
Release: 2016-2 (14)
Keywords: online analytical processing, OLAP-cube, analytical operation
Annotation: This paper presents a formal definition of OLAP-cube operations. There is multidimensional analytical indicators calculation as a sequence of OLAP-cube operations based on proposed formal definition using hydrological monitoring task as an example
