Mapfluence is a San Francisco-based company founded in 2003 that provides an on-demand geocatalog of commercial, open, proprietary and custom data through a hosted mapping and data marketplace platform. It aggregates over 10,000 variables on topics like neighborhoods, transportation, climate and demographics. The platform offers web-based GIS functions, APIs to access and visualize spatial data, and tools to create custom maps and analyze relationships in the data. Mapfluence sees trends in 2011 towards widespread sensor data, real-time data applications, open data and challenges of data literacy as more information becomes available.
