Finding Inspiration And Teaching Myself Location History At The BCS Geospatial SG
With GeoBabel firmly put to rest, I was looking for inspiration when Andrew Larcombe asked me back to the British Computer Society's Geospatial Specialist Group to speak. After a week of drawing a blank, with Andrew sending gentle messages of encouragement via Twitter Direct Message (OI - GALE. TITLE. NOW!!) inspiration finally arrived from a variety of sources. Firstly there was Mashable's History of Location Technology infographic. Then there the brief history of location slides I'd used in a few of my previous talks. There was the rather fine 3D visualisation of geolocation history that Chris Osborne used at W3G and at GeoCom 2010. And then there were two questions that kept cropping up when speaking to people at conferences ... "this location stuff's only recent isn't it?" and "I can't keep up with this geo stuff, it's all moving too fast, where's it going?".
So I started to research this. I knew that location had a long history but I was taken aback to find out just how long that history was. I'd tended to think of the human race using longitude and latitude to work out their location sometime in the 1700's, about the same time as the race to make a working, reliable marine chronometer. It came as a bit of a shock to find out that longitude and latitude were first proposed in 300 BC and were first used to locate a position on the surface of the Earth in 200 BC. Focussing on use of location, on location sharing and on LBS/LBMS and putting GIS to one side I came up with A (Mostly) Complete & (Mostly) Accurate History Of Location (Abridged).
