The Billion Object Platform (BOP): a system to lower barriers to support big, streaming, spatio-temporal data sources
With funding from the Sloan Foundation and Harvard Dataverse, the Harvard Center for Geographic Analysis (CGA) has developed a big spatio-temporal data visualization platform called the Billion Object Platform or "BOP". The goal of the project is to lower barriers for scholars who wish to access large, streaming, spatio-temporal datasets. Since once archived, streaming data gets big fast, and since most GIS systems don't support interactive visualization of millions of objects, a new platform was needed. The core of the BOP is Apache Solr. Some significant enhancements were made to Solr, notably 2D "heatmap faceting" to support spatial visualization.
