Introduction

[2]  Analytical geoinformation technologies and GIS are developed for research of spatial and spatio-temporal data. Analytical GIS first appeared in the 1980s. Development of the Internet and the exponential growth of the volume of digital geographic information (GI) promoted the creation of network GIS. At the present time an increase in GI volumes entails their structuring and developing of thematic data storages, distributed over the Internet and in local networks. In this connection recently the research has focused on development of geoinformation environment of users, comprising distributed information as well as analytical and system resources. In particular, in 2006, ESRI company, a leader in GIS, has announced the development of distributed GeoWeb environment (ArcReview no. 1 (36) 2006). This direction of research in Russia was initiated in 2004 by the RAS Presidium programme "Electronic Earth: scientific data resources and information-communication technologies''. In the framework of this programme in 2006 for the first time the basic version of geoinformation network environment "Electronic Earth'' was elaborated [Arsky et al., 2007a, 2007b]. Some of the most important analytical resources of this version are distributed network GIS: GeoProcessor, version 2.0 (http://www.geo.iitp.ru/GeoProcessor-2/new/index.htm), COMPASS, version V (http://www.geo.iitp.ru/) and GeoTime II, beta-version (http://www.geo.iitp.ru/geotime/), developed in the Institute of Information Transmission Problems (IITP RAS) and supported by the Russian Foundation for Basic Research (RFBR). These GIS are realized as Java applets. The systems support complex analysis of GI, ensure high interactivity of analysis, facilitate integration of data and plug-ins, distributed on network servers and on a user's PC. The connection of plug-ins to GIS kernels allows a user to carry out domain orientation of the system and local data networking ensures its confidentiality.
