Welcome to Spatial Awareness, a regular editorial focused on the maps and the spatial community. Each issue I’ll highlight the most interesting and inspiring things that I’ve found — cool demos, new tools, tutorials, beautiful maps, interviews, behind-the-scenes and more. You can reply directly to me via this email if you have content suggestions, questions, or just want to say hi. You can also unsubscribe at any point by following the link at the bottom of the email.

How is it November already?! Aside from being dark outside way too early, it also means that I’ve been compiling these newsletters for approaching 5 months now — which is rather crazy to think about. I’m still trying to find a schedule for the newsletter that works best for myself, one that I can fit around work and life commitments. I think I’m getting there, though there are still some tweaks I need to make to really nail things down. With that in mind, I’d be interested to hear which sections of the newsletter you like the most, or rather which you care about the least. One option is that I cut down on the amount of material I cover each issue and having some insight into what sections are popular (and not) will help me set out a plan. What’s really helped with motivation to keep this going is your feedback. Each issue so many of you have said so many kind things about the newsletter. It really makes a difference to me and makes the effort worthwhile, so please don’t hesitate to send me a message if you’ve enjoyed this or have any suggestions. 😊

Mini Tokyo 3D
I have a soft spot for 3D visualisations of public transport, I suppose because my first major spatial visualisation was the London Underground in 3D with animated trains in realtime. Fast forward nearly 7 years and this recent visualisation of realtime public transport in Tokyo by Akihiko Kusanagi gives me all sorts of nostalgia. Lovely stuff!

Autumn foliage colours across the United States
Arguably my favourite season of the year, Autumn can completely transform a landscape through the changing colours of leaves. This map by The Washington Post visualises the types of forests across the United States and the colours you might find there. I also like the side-visualisation of leaf types and colours.

Open Infrastructure Map
Infrastructure is fascinating to me, especially when it requires taking a step back to comprehend the sheer scale and complexity of it. The Open Infrastructure Map by Russ Garrett is a fantastic project which takes infrastructure data from OpenStreetMap and visualises it on an interactive map. I find this fascinating as it’s the kind of data you wouldn’t otherwise see on a map generated from OpenStreetMap data. I wonder what other hidden data exists!

GeoTIFF v1.1 adopted as an OGC standard
It looks like being adopted by the OGC has opened the doors for various organisations to declare standard support for the GeoTIFF format, like NASA’s Earth Observation data.

Why all world maps are wrong
This six-minute video from Vox takes a whimsical look at why flat maps are distorted and comparing that distortion between projections. It’s angled more towards people new to maps but its slick production value makes it interesting nonetheless.

Aerialod released by creator of MagicaVoxel
This could be my favourite spatial software release of the year — it’s certainly near the top of the list! What is it? It’s Aerialod by ephtracy, a lovely tool that takes elevation data and uses a path-tracing renderer to produce stunning 3D visualisations. There are already a huge amount of amazing visualisations that people have created using this tool, which are all well worth taking a look at.

PostGIS 3.0.0 has been released
It’s finally here! The official release of PostGIS 3.0.0 has been announced, packed full of new features and performance improvements. This is a big update for anyone who use vector tiles, GeoJSON or want to benefit from the upgrade to PROJ 6. Follow the link above and read the full list of changes as there’s so much more in this release.

qgis2web 3.10.0 adds exporting to Mapbox GL JS
If you’ve ever wanted to export maps from QGIS to the Web then you need to check out qgis2web by Tom Chadwin. This plugin has historically supported exporting your maps as Leaflet or OpenLayer maps, and has recently added support for exporting maps using Mapbox GL JS.

Drawing colour hillshade by hand
It’s so easy to forget that digital isn’t the only way that spatial data can be produced and consumed. I’m guilty of this myself and it’s something I’m hoping to improve upon in the future, even if just printing more of the maps that I create. Or how about drawing maps without touching a computer? This tutorial by Sarah Bell details her process for drawing hillshades by hand using actual pencils and paper. Incredible stuff!

Visualising Amsterdam’s heartbeat
Craig Taylor strikes again with a series of beautiful animated visualisations for TomTom as part of his work at Ito World. The visualisations look at GPS data across the city of Amsterdam and how it can be used to tell a compelling story. The linked article takes a look at how these visualisations were created and the journey Craig took from initial concepts to final production.

How assuming the Earth is “flat” helps speed up rendering in deck.gl
This in-depth article by Georgios Karnas takes a look at the issue of coordinate precision faced by Uber for Deck.gl, their 3D spatial visualisation library. Specifically, Georgios digs into the limitations of floating-point precision in WebGL shaders and details how they worked around those limitations to accurately transform coordinates on the fly without sacrificing performance.

Release of 2m DEM covering the entire Canadian Arctic
A new high-resolution DEM has been released that covers the entire Canadian Arctic. The new data has 2 metre resolution, compared to 5 metres previously. The data has been released as part of the ArcticDEM project.

Global historic tropical cyclone tracks
This fascinating dataset contains the track data for historic tropical cyclones worldwide, from way back in 1841 all the way to the present day. The dataset is updated weekly with the more recent data (later than 1980) being the most accurate, having come from the era of modern satellite observation.

#30DayMapChallenge
This week saw the start of Topi Tjukanov‘s #30DayMapChallenge. The general idea is that for each day of November you create something with spatial data and share it with the wider community. The catch is that each day has a specific theme that acts as both an inspirational aid as well as a constraint. For most people there’s probably no chance of creating something different every single day in November, and that’s completely fine. The premise is to have fun and step out of your comfort zone by following the themes. You can submit as many or as few maps as you have time for over the month.

Sentinel Hub custom script contest

Sarah Bell (@sarahbellmaps)
I’ve featured Sarah Bell a couple of times since this newsletter started, first for her great climbing map for the MonoCarto competition earlier in the year, and also within this issue for her tutorial on hand-drawn hillshade using pencils and paper. Sarah also presented recently at NACIS 2019 on drawing hillshade by hand and you can watch the video of that on YouTube. You can also find Sarah as part of Petrichor Studio where you can see more examples of her amazing work. 👌
