Abstract

Course of investigations "Electronic Earth: scientific information resources and information-communication technologies" is defined by the RAS Presidium programme "Development of fundamental bases for creating scientific distributed information-computing environment in terms of GRID technologies." Department on the Earth sciences, department on mathematical sciences and department of information technologies and computing systems took part in research carried out during 2004–2007. At present, principles of creation and functioning of information-analytical systems in the sphere of the Earth sciences are developed within the framework of six acting internet-portals using contemporary GIS-, GRID-, and WEB-technologies. For the first time a unique scheme, having no analogues, was suggested. It implies interaction of scientist-analyst with developed system permitting to solve previously inaccessible problems on modelling and prediction of geo-objects and geo-processes due to interdisciplinary nature of information and scientific-methodical resources, and owing to thematically mosaic architecture of the portals network. Experimental operation of the system, directed at science information support on a new quality level, has started. In RAS, according to the Programme of the Presidium, information-computing GRID-segment is formed. Acting environment allows to use in research large quantity of accumulated geodata, distributed via the project portals and in the Internet web, the user does not need to make any transformations. Among these data there is descriptive information (publications, references, etc.), as well as numeric information: major geographic (model of relief, river, lake, etc.), geophysical (magnetic and gravity anomalies, etc.) and geological digital data, covering all surface of the Earth. With such environment, digital information is provided for a user from the project servers directly (static or rarely variable information), as well as through proxy-servers for quickly variable information (operative catalogue of earthquakes). System also allows to use in analysis data corresponding to standards of the open GIS consortium – WMS, WFS and WCS. More over, a researcher has a command of different on-line analytical methods and algorithms, part of which is fulfilled in distributed GRID-environment. There is a strong system of rubricators together with programmes of their comparison for data searching and integration. Thus, system "Electronic Earth" has universal information-analytical field in the sphere of the Earth sciences. Owing to the developed standards on metadata and minutes of their information exchange among participants of the project "Electronic Earth", the task of installation of new portals and single computers is not difficult and not expensive for any organizations, dealing with research in the sphere of the Earth sciences. Actuality of results obtained in the fulfillment of the programme, is confirmed by the fact that remote access, search for, exchange and integration of interdisciplinary distributed resources in the Earth sciences and their combined analysis are the base for realization of such projects as Electronic Geophysical year (eGY), global system of monitoring of the Earth (GEOSS), etc.
