The Geoinformation Analysis - Debatable Questions

Debatable questions of ideology and methods of the geoinformation analysis are considered within the framework of geodata classification over levels of generalization of the information. 3 levels of generalization are suggested: initial data; fields of geological and geophysical characteristics; geological objects formally described as cartographic elements. The thesis according to which fields should be used for detection not deposits, and rather homogeneous geological objects, such as intrusions, structures, tectonic unconformities, zones of better collector proprieties, etc. is proved. At the third level of generalization of information these objects are used for the forecast of complex geosystems, including various deposits. In consideration of the problems solved at the second level of information generalization, debatable questions of interpolation, division of fields and estimations of geological objects parameters from the geophysical data are discussed. In particular unacceptibility for geology of the so called metrological approximation of fields is proved. Arguments in favour of the statistical theory of interpretation are given: geological interpretation of the geophysical data always consists in transition from priori evaluations of objects’ parameters to posteriori evaluations.
