The dissemination of methods of applied (spatial) statistics, i.e., geostatistical methods, to representatives of various scientific disciplines (geology, mining, environmental engineering, climatology, renewable energy resources, etc.). The attendees are expected to have knowledge and expertise in diverse areas of significant interest for the national economy.

The creation of opportunities to acquire both basic and applied knowledge, founded on a firm theoretical background, of geostatistical methods.

The development of practical skills for the use of geostatistics and specialized software during the Workshop sessions.

An original and innovative (modern) research methodology which involves the use of geostatistical methods, and it is applied to the spatial analysis of the variability of regionalized variables (i.e. variables whose position in space is described by two (plane) or three coordinate values and possibly time as well for dynamic phenomena.

The scope of applications of the geostatistical methodology is increasing following the creation and availability of spatial databases in various scientific areas, and due to the increasing capacity (content) of existing databases. This increasing availability of spatial data generates new possibilities for many fields of research, and the geostatistical methodology provides a practical suite of tools that can be used to process and extract information from spatial data.

Scope of the Workshop

  2. Research methodology based on the geostatistical approach.
