Geospatial Data Visualization: WorldMap Integration by Raman Prasad


Published on

The Boston Area Research Initiative (BARI) has started work to integrate the Dataverse and Harvard WorldMap systems. This will give Dataverse users the opportunity to map shapefiles as well as tabular files. The maps will be saved in the WorldMap system, allow users to take advantage of the WorldMap’s rich feature set as well as share the maps through Dataverse. This effort involved building APIs on both systems and connecting them via a small web application.
