Changes of Switzerland's 38 biggest glaciers since 1850 (Veränderung der 38 grössten Gletscher der Schweiz seit 1850) – reworked by me 3

Reworked: “Gletscherschwund” by TagesAnzeiger

Today, Swiss daily TagesAnzeiger featured a great piece about climate change and shrinking Swiss glaciers. The article features: an animated GIF showing the overall area of glaciers that was lost to melting as compared to the area of the canton of Zurich. This is useful...


Visualising the last glacial maximum correctly

A few days ago, Swiss Geoportal (/the Swiss federal geodata infrastructure) tweeted a link to a visualisation of the largest ice extent over Switzerland – i.e. the last glacial maximum, LGM for short: They used a rather famous map of the LGM and draped it...


Switzerland tile map

(Blogpost auf Deutsch unter www.geo.ebp.ch) I believe in abstraction for conveying information, or ‘rough’ context for information, efficiently. Since a while, hex and square tile maps are all the rage in the US. Check out this post by the npr visuals team on the technique,...


Visualizing group sizes and inter-group flows

A few weeks ago, I came across the following graphics on Twitter: They depict voter share per party (including absentees, in grey) (top) and voter flows between different parties in the 2015 cantonal elections in Zurich. The graphics are produced by sotomo, a research company at the nexus...


Slide design and public speaking

I have a Slideshare account that I use to publish slides of presentations I’ve held (if it’s okay to publish them, which is the case only very occasionally). Sometimes Slideshare sends me e-mail news that I more often trash than skim. But yesterday a post with the...


The best in cartography and infoviz of 2014

I will abstain from compiling my own list of “The best …”. Instead, I give you a small list of lists to be consumed at your pleasure: The Best Data Visualization Projects of 2014 by FlowingData All of Nathan’s picks “are interactive or animated or both”. “Telling for where...


To all you Geohipsters out there

Have you heard of the Geohipster blog? It’s the self-described place for people who ‘grow their own organic vertices, use gluten-free topology or only geocode by hand, in small batches’. And I give at a big recommendation, put it into your feed reader. And relax, you don’t need to be a...


Geocoding Twitter users – The #SwissGIS map

Recently, I’ve been experimenting with some Twitter-oriented hacks together with my friend Tom. A very preliminary result of these activities is what I call the #SwissGIS map. Some, just a little, history: Over the last few years, I have been collecting Switzerland-based Twitter users that talk about topics...


The Data Worker’s Manifesto

This article is a re-post of an article that first appeared on www.geo.ebp.ch. Last week I gave a talk at the 8th instalment of the GeoBeer series on EBP’s Zurich-Stadelhofen premises and sponsored by EBP and Crosswind. It was titled State of the Union: Data as Enabling Tech‽...


Wikipedia cartogram mentioned by Smart Hive

Big honour: my interactive visualization Infor­ma­tion Imbal­ance: Africa on Wikipedia for the OII Internet Geographies blog has been featured by Smart Hive under the heading Non-traditional data mapped to geography. Thanks for the mention!


When NOT to use maps

Recently, I’ve stumbled across Noah Iliinsky’s Where 2012 talk When To *Not* Use Maps. The title immediately intrigued me. As a geographer and data consultant I’m convinced, an important part of my work lies in the question what tools best fit a purpose or a goal I...


Minard’s march – a hallmark visualization, rightly so?

Some days ago, Martin Elmer (@maphugger) tweeted Numberphile’s video in which they highlight the famous Minard map. Martin and I exchanged a series of tweets on the topic: Martin had some substantial criticism of Minard’s graphic. Maybe, graphic is the crucial word here: A part of...
