Elements of system and Su-field analysis of environmental monitoring tools (using the example of the geomagnetic data)

Decision-making in the field of technosphere safety is based on timely receipt of up-to-date and complete information about the state of the environment. Geomagnetic monitoring plays an important role in reducing the negative impact of extreme geophysical events on objects and systems of the technosphere (power lines, communication systems, railway automation, etc.). In this paper, geomagnetic monitoring is considered from the point of view of system approach, the main problems of obtaining geomagnetic data are identified and formulated, the main of which is incomplete coverage by the monitoring network. Using a Su-field representation, an approach is proposed and formalized, that extends the process of obtaining and using data with an interpolating computer model. The implementation of this model uses adaptive spatial interpolation to determine the optimal interpolation methods, taking into account the geographical location of the interpolated points and the global geomagnetic activity index. The effectiveness of the approach is demonstrated by the example of the geomagnetic information of the SuperMAG project using a web-based software solution.
