That led me thru a brief history of mine, from early field mapping thru computer mapping and GIS to big data and disruptive tech. The latter is where the distinction between data and maps is clearest. To put it simply in my sphere:
Big geo-data originates in the enormous input from current sensorsIn oil&gas this could be 4D Seismic and Measure While Drilling. In global monitoring that could be millions of distributed sensors. While apps like Earth exist, Mansour Raad notes as below that …like the others, they lack the spatial aspect when it comes to my world.

AGI's Geo Big5 events highlighted big data in London this week. As mentioned in my map blog, topics ranged from LiDAR and UAVs to cash registers and NFCs (inventory control and touch-card and -phone payments). And their delegate pack asks this:
- What is big data, how does location augment it and why should I care?
- Hasn’t location data always been big?
- What does location bring to the party?
- Where is big data and location really adding business value?
What struck me about this show is that whilst largely driven by vendors - other than M&S a British retailer (keynote ) and Telefonica a Spanish telecom - it was very business-driven looking for outcomes: the tech was very much left in the tech sessions and maps most definitely moved into the background.

Almost fifty year later this is what geocomputing environment looks like with real time weather (mega)data... to the point where the UK Met Office and US NOAA offer space weather forecasts!
