Spatiotemporal knowledge is the knowledge with temporal and spatial characteristics formed by summarizing and condensing the information of spatial location, shape, distribution, relationship, movement, change and trend of entity.Spatiotemporal knowledge center is a service platform or environment for acquiring, accumulating, creating, evolving and utilizing spatiotemporal knowledge.The construction of space-time knowledge center is an opportunity and challenge for intelligent mapping. The relevant research is still in the initial stage of exploration, and there is no mature construction and service mode to be used for reference.This article aims at the new needs of natural resource management for surveying and mapping services, draws on the practice of knowledge center construction at home and abroad, incorporates the relevant concepts of intelligent surveying and mapping, and proposes the concept, connotation, technical framework, subject realization methods and research progress of the spatiotemporal knowledge center, and finally introduces the future development direction of spatiotemporal knowledge center from three aspects of development trend, key technology and engineering application.
