Cartograms

Not to be confused with Mapbox’s nonsensical hijacking of the term for creating colour styles, cartograms are extraordinary map types. The relaunch of Worldmapper in April 2018 celebrates this form of mapping. As a Fellow of the Royal Geographic Society, one of the perks is a subscription to the excellent Geographical magazine. The recent issue had an excellent article on ‘Mapping the World’ (May 2018, p.66). The article covers the April relaunch of Worldmapper, which originally began in 2006.

Above is an extract of a gridded cartogram showing Germany’s vote turnout in 2017, using an equal population projection where every person in Germany gets an equal amount of space in the map.

“It is not only a fully redesigned website, but also redefines what we want Worldmapper to become over a decade after it has first been released: An atlas for the 21st century that is mapping our place in the world using cartograms.”

The relaunch included 125 new maps and will continue to grow; currently, at date of posting, there are 337 world maps, excluding other projects. The website will increasingly use more diverse cartogram techniques, such as gridded cartograms, as well as including maps at different scales such as country-level mappings.

The UK population cartogram above was created by Benjamin Hennig, University of Sheffield. It clearly shows what an urban population we are.

Briefing a Cartographer

CARTOGRAPHERS (map designers) work like many others engaged in design fields—they need clear briefs. Not only does a clear brief help the cartographer, but more importantly, it helps you structure your thoughts and clarify objectives. [ more… ]

Sketchfab

I’ve posted this article for no more reason than to demonstrate one of the best and easiest to use browser-based 3D viewers available, not to mention an excellent resource of 3D models—Sketchfab. [ more… ]

Illustreets

No sooner had I picked up on one new online mapping framework, the OS Open Zoomstack, than another appears! Illustreets follows the usual formula, but with each new framework that gets released [ more… ]

OS Open Zoomstack

The world of online mapping frameworks moves apace! Now, even the monolithic mapping organisation, the Ordnance Survey, is involved. In July, they launched OS Open Zoomstack, providing vector tiles of their open data themes. [ more… ]

Visual Thinking

Having been embedded within graphic design and cartography for 30 years now, one recurring disappointment for me is the amount of ‘new’ conceptual and theoretical thinking, and object creation, that really is not new. [ more… ]

kepler.gl

Uber—who would thought—have released kepler.gl, an open-source geospatial toolbox. It’s designed to provide the easiest way of visualising geospatial data and gaining useful insights. [ more… ]

Cartograms

Not to be confused with Mapbox’s nonsensical hijacking of the term for creating colour styles, cartograms are extraordinary map types. The relaunch of Worldmapper in April 2018 celebrates this form of mapping. [ more… ]

Google Earth

When it was first released 16 years ago, it was an incredible virtual experience to be able to travel around the globe and look at anywhere in a level of detail previously not seen, and it still is today! [ more… ]

National Geographic

Since the very first issue in 1888, the National Geographic magazine has been the benchmark for quality researched articles supported by well-crafted graphics. [ more… ]

Heightfields

There is always an aspect of work that emerges out of error, experimentation and/or serendipity. [ more… ]

Big Data Visualisation

Visualisations of ‘big data’ have been commonplace over the last few years, though their is still much debate to be had about the value of many of them beyond their visually interesting presentation. [ more… ]

Choosing a Monitor

Screen estate and colour are very important to a cartographer. Maps can be any size from A6 to more than 5m×5m square. [ more… ]

An Open-source World

Over the last few years we have seen the release of numerous mapping platforms/frameworks to allow the manipulation and representation of open-source mapping and other spatial data. [ more… ]

OS Maps – the App

Recently, the Ordnance Survey (OS) updated an app for both mobile and desktop devices that utilises their 1:25,000 Explorer and 1:50,000 Landranger maps—classic OS mapping at it’s best. [ more… ]

Swiss National Mapping

Swiss topography has long been regarded as the epitome of this form of mapping, often characterised by the iconic hill shading techniques of the late Eduard Imhof, professor of cartography at the Swiss Federal Institute of Technology. [ more… ]

Relief Shading, Part I

As we seem to be moving in to presentational modes where 3D (mapping) is becoming ever more commonplace, enabled by software and hardware advances, it is relevant to look back [ more… ]

Mac Pro 5,1 resurrected?

I decided to raise the bar on my workstation and go for something with a little more grunt, and that would be up to the job for the next 2–3 years. [ more… ]
