Abstract

Abstract:

The digital twin system of geospatial information is an important support system for geospatial information service and an important foundation for the development of intelligent society. The digital twin system of geospatial information has more special requirements in terms of accuracy, systemization and reliability, compared to other industrial digital twin systems. This paper describes the basic rules of the establishment of the geospatial digital twin system from perception, description and mapping to statistics, prediction and deduction. It is emphasized that the perception of geographic entities should be accurate, the space-time reference should be consistent, the attribute description should be correct, the historical information should be dependable, the mapping relationship should be complete, the statistic trend should be systematic, the variation prediction should be rigorous, and the auxiliary decision making should be scientific. The related research topics of the geospatial digital twins are generally classified. The problems to be paid attention are listed. Finally, the relationship between the geospatial digital twin and spatio-temporal intelligence is discussed. The basic process and key technologies in the construction of geospatial digital intelligence system are pointed out.

Key words: digital twin, geospatial information system, spatio-temporal intelligence, geospatial entity mapping, dynamic deduction
