As a knowledge product of scientific and cultural resources, the atlas encompasses multi-source, multi-scale, multi-temporal, multi-type, and multi-disciplinary knowledge, information, and data. Based on the construction and application practice of the information sharing service platform of "China Thematic Atlas Resource Network", this paper proposes the knowledge service needs of atlas resources in the era of informatization and big data, and fully integrates national strategic and new technologies of the times, builds a multi-level knowledge service system framework including content system, expression system, technology system, and application system, further explores a multi-level knowledge service model for field applications of atlases.
