Bio
Asst Prof Gastner is an applied mathematician and data scientist. His main interests are at the interface of data visualisation and cartography. Together with Yale-NUS students, he is currently developing go-cart.io, a user-friendly online tool to construct cartograms.
Cartograms are maps in which areas (e.g. countries or provinces) are rescaled in proportion to a thematic mapping variable (e.g. population size or gross domestic product). Unlike conventional bar or pie charts, cartograms can represent correctly which regions share common borders, resulting in visualisations that can be the basis for further spatial statistical analysis. Cartograms have a long tradition, dating back to the 19th century. In the 1970s, computer algorithms were developed to automate the production of cartograms, but the procedure remained cumbersome and slow. Dr Gastner has developed a faster algorithm that computes cartograms in a matter of seconds. He is now working on an intuitive user interface for cartograms. His objective is to share free open-source cartogram software that is accessible to the general public.
