Web Mapping

Part 1, The Basics Children of the millennium will never know that there was a time before the internet when we, the cartographers, engineers, and surveyors had to relate geospatial information through the medium of paper. Although the internet has been around since the late 1980s, it wasn’t until 1996 when the world got the...

Why 3D GIS Is the Future

“The world we live in is a three-dimensional world, so why do we map it and analyse it in just two dimensions?” —Dragons8mycat, 2013 In the last five years, we, the GIS industry, have made some fantastic advances. So, why is it that we are so slow with the adoption of using 3D data? Surveyors...

Further Adventures with 3D GIS

Last year I posted about this awesome plugin called “QGIS2Threejs” [here] and how it was possible to quickly render 3D visualisations for free using the open source GIS, QGIS. At the time I fudged some wind turbines as it was impossible to import models. Furthermore, I avoided too much detail as any imagery would look...

Recreating the Ordnance Survey Explorer Maps with Open Data

The holy grail for many (UK) map users is the Ordnance Survey 1:25,000 scale “Explorer” map. Not only are they easy to read due to the fantastic cartography used, but they also have information which is hard to source such as public rights of way, National Trust & Woodland Trust sites, even wind farms.

Why Your Maps Should Get in Touch with Their Feminine Side

Google does it, Apple does it, but do your maps use landmarks to improve users’ familiarity? More to the point, why aren’t popular landmarks a standard GIS dataset? For more than 10 years now we’ve known that the majority of the population use spatial recognition to navigate. When I say “majority.” I mean women and...

Quantum Navigation

Above: The Royal Navy submarine HMS Astute. Credit: LA(Phot) Paul Halliwell/MOD. Will freezing sub-atomic particles one day supplant GPS as the primary navigation technology? Many of the most accurate measurement devices, including atomic clocks, work by observing how atoms transfer between individual quantum states. The longer the atomic transition can be observed, the more precisely it...
