Strictly Spatial #29

30 November 2016


With December almost here it’s time for those movember-stashes to be removed – unless you’re father Christmas for your work Christmas function! In this fortnight’s Strictly Spatial we explore street art in Christchurch, look at a TRON inspired basemap and see just how long Trump’s wall actually is!

Strictly Spatial 29aPost-earthquake, street art has become a draw card for visitors to Christchurch. Local and international artists have visited the city to stamp their own creations on blank city walls. This has resulted in a vibrant and dynamic scene. Unfortunately, there was no definitive source of all these murals. Lindsay Chan took this as a challenge and mapped out all (as many as she could find) the murals. You can check out her story map here and let her know about any she might have missed.


Strictly Spatial 29bMaking non GIS and spatial people interested in maps is often a challenge. Companies like MapBox and OSM are creating stunning and informative basemaps that make us GIS folk tingle with joy. Going further there a plenty of ways people have customised these basemaps even further. However, this custom basemap takes it to the next level. The TRON2.0 basemap is a bright, animated basemap inspired by Tron and built using Mapzen. Check out how they made it here.

Lidar, NIR (Near InfraRed) and true colour imagery taken from drones (UAVs), lanes or satellites can reveal a lot of information about our landscape that we can’t see when we’re on the ground. Once this data has been captured, spatial modelling, analysis and statistical tools can be used to interpret the data. A combination of these GIS processes are being used in Landscape Archaeology. GIS Lounge has written a short piece on the subject, which you can read here.

Strictly Spatial 29cOne of the big promises that came out of Trump’s presidential campaign was to build a wall separating Mexico and USA. This wall is proposed to be a massive 3,200km long. That’s the equivalent of three and half return trips from Christchurch to Dunedin – via the ‘new’ inland route. A German newspaper has published an interactive map that allows you to drag the outline of the proposed wall across the globe so you can understand just how long this wall will be.

That’s all for this fortnight’s Strictly Spatial. We hope you enjoy the start of the festive season! Keep in contact through Facebook, @InterpretGS, LinkedIn or email.
