Strictly Spatial 12a


Hi all, welcome to the 12th edition of Strictly Spatial. Hope you’re keeping well and that daylight savings hasn’t thrown you too badly! In this edition of Strictly Spatial we look at global risk maps, Facebooks population map, roundabouts and more!

Travelling to a foreign country comes with plenty of excitement but also some hesitation. You want to make sure you’re safe. Part of being safe is knowing about the country and what day to day risks you might face. The Global Risk Map takes news stories and current affairs and generates risks for each country. Do however, take it with a pinch of salt.

For those of you sharing (or wanting to share) your spatial data how do you do it? Here at Interpret we make use of Esri products to publish and distribute spatial data. However this is not the only way. This article by David Raths looks at what other options you have when the time comes to share and publish your data. It very informative and highlights products I have never heard of.

Strictly Spatial 12b3With more than one billion active Facebook accounts, Facebook is in a pretty strong position to gather massive amounts of (big) data. With all this data, Facebook is creating their own population maps. The use of this social network data can have invaluable benefits to many different fields of studies. Check out GIS Lounges’ article on these maps here.

How many of you have wondered, when looking out to the ocean, what country you’re ‘looking’ at? Maps from cartographer Any Woodruff aim to solve this problem for once and for all. Using some nifty angle calculations and playing with projections, Woodruff has done a great job at visualising these ‘straight’ lines. He’s written a really interesting blog on the subject here. 

Have you heard the saying dig a hole to China? As a child I know I tried, but something stopped me - the concrete under my sandpit. Beside this small setback, there’s numerous problems with this saying, one of them being the Earth; it’s pretty dense and very hot. Ignoring this, we then need to think, if I dig straight down (and then back up) where will I be? Well if you check out this map you’ll find out. Looks like if I dig down from our offices I’ll end up on the coast of Spain! Time to start digging!

Strictly Spatial 12d3Roundabouts are fairly common here in New Zealand. In France there is one roundabout per 45 intersections where as in America, there is only one roundabout per 1,118 intersections! Using data from Nokia’s Here maps, Damien Saunder mapped all the roundabouts in America and compared the number of them to other countries. He noted that between the states of Wyoming, South Dakota and North Dakota they shared less the 50 roundabouts. Check out the resulting graphics and maps here. 

That’s all for this fortnights Strictly Spatial. Like always if you’ve any interesting GIS stories you’d like to share with us get in touch! We’re on Facebook, Twitter, LinkedIn and good old fashion email
