This paper reviews the 60 years of development from traditional
surveying and mapping to geospatial information intelligent service science.
Three important stages of geomatics development from simulation to analysis
and then to digitization are summarized. This paper analyzes the development
of geospatial informatics in the era of digital Earth, and then discusses the latest
progress of geospatial information science towards real-time intelligent service
in the era of intelligent Earth, and focuses on the three development levels of
“Internet +” space information intelligent service.
