Analysis and processing of geophysical data and visual presentation of results of processing are important tasks facing modern geophysics and other geosciences. Multiple new mathematical methods of interpretation and modeling geodata are developed already and are being developed, but their realization, application and publication often turn out to be a very expensive and labor-intensive task. It determines the difficult task of developing new methods of processing data on geoscience. The paper addresses the idea of data and algorithms'nbsp; integration in an integrated environment of geographical information system GIS by developing a centralized catalog of algorithms. The catalog represents a sub-system of GIS, providing access to specialized application algorithms for geodata centralized processing, carried out by GIS-server. GIS-server comprises program software and technical equipment, necessary for performing algorithms and transmitting results to users, and also a storage of geophysical data and results of their processing. Thus, for data processing and providing results it would be sufficient to use web-browser, and there is no need to use expensive program software. GIS ensures integration of application algorithms of geodata processing, providing scientific community the environment for mathematical realization of algorithms and presentation of results of their application. Another considerable advantage of this environment will be creation of an integrated and constantly updated library of geodata processing methods.
