The acquisition method, application mode and service direction of big data are
undergoing fundamental changes. Starting from the influence of big data on geospatial
information, this paper mainly discusses the change of geospatial information service
mode, interprets the connotation of knowledge service, and discusses the key strategies
for realizing knowledge service of geospatial information, so as to provide reference
