Beyond Mapping Population Density: Cartography for Big Data
Big data sets are not only 'big' in size and/or number of records, but also in the variety of stories and insights they hold. Piling millions of points on a map can be beautiful and eye-catching, but what story does it tell? Each coordinate in the data provides the opportunity to extract meaningful patterns and observations at multiple scales over a variety of topics. The result? Maps driven by big data that are both beautiful and informative.
Using a big data example, this session walks through some methods (and challenges) of representing millions of points on a map in a meaningful way. We will discuss topics around data aggregation, representation through scale, and design -- all from a cartographic perspective.
