  The study addresses the issues of development and functioning of the software and hardware system intended to provide secure and reliable communications for remote corporate subscribers over the networks with cellular or wireless internet access. The system requirements necessary to maintain secure connection of end users are indicated and discussed. Based on the analysis of existing solutions, the structure of novel software and hardware system which fulfills indicated requirements was proposed, implemented and tested in several Russian and Canadian companies. Results showed that developed system allows secure and high quality voice and data transmission between subscribers over the 3, 4G and Wi-Fi mobile telecom standards.

  The objective of this research is the study of the problem of the lack of high-quality geospatial data needed for designing customized GIS projects. It is suggested to solve the problem by using free network resources of vector and raster data with diverse spatial resolution and area coverage which are in open access. The study describes the largest free sources of geodata, the use of which allows to solve the problem of the lack of spatial information as regard to those regions where measurement of desired characteristics has not been performed or owing to some reasons is in accessible. The study presents specific examples of compatibility of heterogeneous spatial characteristics, received from various sources in the unified coordinate space of the environmental GIS project. The algorithm for research projects creation with the help of various methods of data interpolation for the spatio-temporal analysis of environmental characteristics is presented. The conclusion is drawn that the use of free data in the training course designed for ecology students provides wide opportunities for further inter disciplinary researches.

  The aim of our study was to develop specific methods that make possible to identify and visualize focuses of ecosystem pollution for the determinationof the permissible anthropogenic impact boundaries and prediction of their development. The two-level spatial zoning method is considered through the example of an environmentally unfavorable region of the Russian Federation. The set of analytic methods is proposed, which was applied to determine the preliminary boundaries of areas using the clustering procedure, while the algorithms of correlation and regression analyzes allow to assess the uniformityof specific environmental characteristics in selected areas.
