Technology change has created an inflection point for geodata. Mobile devices, social media, retail transactions, and more generate a tremendous amount of data. The volume, variety, and velocity of data is increasing. New technologies are being developed to handle the huge amounts of data. The problem is more complex than simply having a big relational database. This talk will present an overview of open source geospatial technologies which enable big geodata on the server and little geodata on devices and other clients to make it useful with the right context at the right time. More than technology for technology's sake, use it to do something meaningful.
