Studying of plate tectonic motions is one of the main problems in geodynamics. Modern observational data from space geodetic techniques give us a possibility to estimate the plate rotation parameter (three components of the rotation vector) and some plate deformations. It's important for solving the most geodetic and geodynamic problems, such as: correcting the reference frames, investigating the events of ebb and flow, predicting of earthquakes and others.

Every geodynamic investigation needs to be illustrated by corresponded maps. Information technologies allow us to operate with big amount of data sets.

With the support of GIS we can make the geodynamic monitoring, systematize and visualize data sets and results of investigations, creating thematic maps, as well as founding the correlation of data from geodesy, geodynamic, seismology and other sciences. We developed the structure of future geodynamic GIS and created the system of electronic maps "Geodynamics", which includes earthquakes and plate tectonic motions maps. For last chapter observational data from space geodetic techniques (GPS, VLBI, SLR, DORIS) was used.

This work is useful for scientists study geodynamic processes.
