Strictly Spatial 13

Posted by on 21 April 2016


Hi all and welcome to the 13th edition of Strictly Spatial. We promise you this one won’t bring any bad luck! In this edition we take a look how the ANZACs made use of aerial imagery, look at an amazing map showing the composition of sounds in streetscapes and for you Game of Thrones fans, we have something special at the end (no spoilers)! Sit back, have a read and enjoy.

ANZAC cove mapANZAC Day is a time to remember those who have fallen for our country. Two blog posts from Lincoln University (Part 1 and Part 2) published for last year’s centenary contain interesting details, maps and imagery from the ANZAC operations. What amazes me most is how far our mapping technology has come, but also, how advanced the militaries technologies were. In 1915, using the first ever aircraft carrier, aerial photos were taken of ANZAC Cove and Gaba Tepe. These were then manually stitched together to create a map of the area. Pretty amazing work to occur over 100 years ago! Read about it in Part 2 of Lincoln Universities blog.


Streetscape map

Noise in a city can come from many sources; wildlife, humans, traffic and entertainment. This map shows the composition of sounds on streets in various cities around the world. And it looks fantastic – check it out here.  The combination of bright colours on a mostly black basemap is brilliant. Clicking on a street will bring up some more detailed information on the source of the sound. The creators have a short write up on the process which they took to create the map. Unfortunately, no New Zealand cities have been mapped. 

 Often when browsing Google Maps imagery, you can come across some pretty spectacular views. When you dive into street view, you can encounter bizarre scenes and people acting weirdly. Due to how the multiple cameras used to capture Google Street View imagery are stitched together, you can often get some strange, and often nightmarish ‘glitches’. The Quartz blog has compiled a list of the scariest such images and has kindly shared them. Check them out here.

Speaking of Google Street View, Bruce Wayne has allowed them to capture the inside of the Batcave and Wayne Manor! Check out the links here and have an explore.

Property numbersHere in New Zealand we number our properties with odd numbers on the left, and even numbers on the right. This gives a zig-zag appearance to the numbering on our streets. Not all countries use this approach, some use the horseshoe approach which results in the highest numbered building being opposite the lowest numbered building at the start of the street. Each of these methods are fairly easy to work with separately, but when some streets use the zig-zag method and others the horseshoe approach, things get complicated. Berlin is one such city. Check out this map to see which streets in Berlin follow which rule.


Game of Thrones map

There’s two types of people in this world. Those who know what epic TV show is airing its new season on the evening of Sunday 24th (USA time) and those who don’t. For those of you who don’t watch Game of Thrones (GoT), you’re missing out. For those of you who do watch GoT, check out this awesome webmap/app. This webmap/app and its associated REST API were created as part of a JavaScript course at the Technical University of Munich. If you go into the characters link you can see all this exciting data, along with their likelihood to die, and a map of where they’ve been in each episode. I really hope my favourite character doesn’t die!

Strictly Spatial #12

Strictly Spatial 12a

Posted by on 8 April 2016


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
