Please find below some supplementary material for the paper The detection of "hot regions" in the geography of science: A visualization approach by using density maps by Lutz Bornmann and Ludo Waltman (paper, preprint):
- Step-by-step instructions for making a geographical density map (download).
- Software for making a geographical density map + some additional files (download).
Other material and software can be found elsewhere on the web:
- Quantum GIS, an open source geographic information system.
- Freely available shapefiles: GeoCommons and GADM.
Some examples of geographical density maps are shown below. We refer to our paper for more information on these examples.
Our maps can also be viewed using Google Earth. The following maps are available:
- Highly cited publications in biochemistry, genetics & molecular biology in 2007 (download).
- Highly cited publications in physics & astronomy in 2007 (download).
- Nature and Science publications in 2007 (download).
- Nature and Science publications in 2009 (download).
