The detection of “hot regions” in the geography of science—A visualization approach by using density maps

Lutz Bornmann () and Ludo Waltman

Journal of Informetrics, 2011, vol. 5, issue 4, 547-553

Abstract: Spatial scientometrics has attracted a lot of attention in the very recent past. The visualization methods (density maps) presented in this paper allow for an analysis revealing regions of excellence around the world using computer programs that are freely available. Based on Scopus and Web of Science data, field-specific and field-overlapping scientific excellence can be identified in broader regions (worldwide or for a specific continent) where high quality papers (highly cited papers or papers published in Nature or Science) were published. We used a geographic information system to produce our density maps. We also briefly discuss the use of Google Earth.
