The use of cartograms for BGS data and information representation

Cartograms are shown to be superior to both choropleth maps and bar charts, as they are
designed to deliver geospatial statistics effectively and efficiently. This report presents the results
of research in establishing the potential for the use of area cartograms for science information
delivery. The research involved establishing an overview of all the types of cartogram used;
noting the types of data used in their creation and identifying similar sources of data that may
prove appropriate for use in cartograms. Test examples were created and presented along with an
evaluation as to their effectiveness and efficiency in communicating spatially orientated datasets.
The work was carried out as part of the Data Representation and Presentation project for the
Geospatial Capture and Solutions team. This forms part of a wider research project investigating
new ways in which BGS can display science and information more effectively to a broad range
of audiences.
