Spatio-Temporal Visualization of Global Phenomena: 1850 to the Present
Track: Web Mapping
Authors: Ben Lewis
Our center was hired by the Harvard Business School to build a system for visualizing change over time at the level of nation state, for a wide range of variables from 1850 to the present. This project presented several challenges including: 1) development of GIS boundary data to depict change for the 150 year period, 2) the coding of polygons to depict 48 separate phenomena. 3) building a temporal mapping application capable of supporting many users without tile caches or vector services.
