摘要
We present elements of technology for spatio-temporal data mining aimed at studying natural processes by temporal sequences. The methods considered are applied to the analysis of Earth's surface deformations by GPS and InSAR measurements of ground displacements. Often, the study of earth deformation is limited to the analysis of average strain rates only. It is shown that inclusion of the temporal component of GPS data allows one to find the relationship between seismicity and dynamics of the fields of horizontal surface deformations. Accounting for the temporal component of InSAR data allows identifying urban areas of land, which differ not only in the intensity of deformations process, but also in the type of their dynamics. The methods considered are realized in GIS GeoTime 3 (http://www.geo.iitp.ru/GT3/).
