In this week's podcast: Could geo-spatial information be the next dimension for big data? Knowing where something, or someone, is is growing in value to retailers, engineers, governments, and the military. We speak to GIS specialists Dan Monk, technical architect at Atkins, the consulting engineers, Andrew Corcoran, of the energy and environmental consulting company West Coast Group, WO2 Giles, of the UK's Ministry of Defence, and Euan Cameron, CTO for the applications at GIS vendor Esri, on the increasing importance of location information.
