Why ‘space weather’ is bad news for map making

What is ‘space weather’? Well this generally means solar flares – or as you might have heard on the news recently – coronal mass ejections to give them their full title!

Solar flares are related to sunspot activity which tends to run in 11 year cycles. We’re now entering the period where sunspot activity is increasing to amaximum for the current cycle. On Tuesday there was a big flare – the biggest for 4 years – whilst tonight those of you in Scotland might even get to see the Northern Lights as a result, so keep your eyes on the skies!

So what’s all this got to do with mapping?

Focus on Cartography – part one

Mention a cartographer and people will think of someone who draws maps. Well, it’s obvious isn’t it? Having spent a few hours talking to various members of our Cartography team though, I’m actually amazed at the breadth of areas they cover. So, if you’ve already read our ‘day in the life of a surveyor’ blogs, read on to find out what happens once that surveyed data gets inside the building.

Our Cartography team, which is really lots of separate teams with different specialisms, is led by Huw, and they are responsible for deriving and maintaining cartographic databases, and providing the finished data for Ordnance Survey national series paper and data products. They do this through the manipulation and enhancement of our core databases. But as well as this ‘core’ work, they work on lots of other projects from specialist maps to innovative work on the effects of colour vision deficiency on mapping.

Explorer team

Sandy leads the Explorer team. Unsurprisingly, they work on the design, editing and updating of databases for our very popular 1:25 000 OS Explorer Map. The team also work on the data for our OS Select bespoke product where customers can centre a map on an area of their choice and on our digital product, 1:25 000 Scale Colour Raster.
