Bibliometrics is an important methodology to mine and analyze the information of the discipline development trend. Visualization is one of the hot topics in the development of bibliometrics. Based on the bibliometric methods and the spatial analysis function of GIS, the development trend of global geoscience research from 1994 to 2018 was comprehensively analyzed and the visual analysis mainly focused on the global geoscience articles, the geographical distribution of the main productive authors and main research institutions, and the spatiotemporal migration of the centroids of global geoscience research. The results showed that the global scientific output of geoscience increased significantly from 1994 to 2018. The centroids of geoscience articles gradually migrated to the southeast of the northern hemisphere, and the changing trend was mainly reflected in the longitude direction. The international collaboration was deepening year and year, more and more countries have participated in the geoscience research. The USA played an important role in global geoscience research and the scientific research ability of China has improved significantly. Santosh M of China University of Geosciences has published the most articles, while articles produced by Zhao Guochun have received the highest attention. The Chinese Academy of Sciences and Chinese universities and colleges were the main productive institutions. The results can provide beneficial reference for the discipline construction of geoscience and relative research.
