As noted in the previous GeoCurrents post on the “deserts” of Colombia, Colombia is usually considered to be the world’s rainiest country, receiving some 127 inches (3249 mm) of precipitation annually, averaged over the entire country. Learning this fact inspired me to make a map of average annual precipitation by country, which is posted below. […] The post Average Annual Precipitation by Country Mapped appeared first on GeoCurrents.
A recent GeoCurrents post suggested that the electoral geography of the United States has strikingly deviated from that of Latin America during the 21st century. In the U.S., population density has become one of the main influences on voting patterns, with cities favoring candidates on the left and the countryside preferring those on the right.

Dividing the terrestrial world into the “Global North” and the “Global South” is becoming increasingly common. Simple versions of this “two worlds” model have a relatively clean north/south division, with only Australia and New Zealand falling out of place as southern outliers of the North. The Wikipedia map posted below, however, includes a few additional […] The post The Misleading Concept of the “Global South” appeared first on GeoCurrents.
(Note: Last December I began work on a series of posts focusing on the geography of wealth and corporate power. After a single post on the location of corporate headquarters, I had to suspend my work on this topic. This post includes maps that I made at that time, based on data from late 2025.)

In a recent post on Attila Bátorfy's Cabinet of Infographic Curiosities, he highlighted the Czech-born geographer and statistician Anton Leo Hickmann and his early contributions to data visualization. Hickmann’s most influential work, the Geographisch-statistischer Universal-Taschen-Atlas, was published in 1894. You can view it from the Austrian National Library. it’s full of interesting charts and maps but what got my attention was this diagram. I’ve posted before about comparative mountain heights. There’s even a post on the David Rumsey Map Collection showing many different examples of these but this one is new to me. Note that I stitched two atlas pages together to make the image above. The title translated from German is “Idealized view of the most significant highs and lows“. This graphic has two layers, the top one for mountain heights sitting over a layer of sea and ocean depths. The top panel shows Europe in the foreground and from left to right Africa, Asia, South America New Zealand, Australia and Hawaii. Mount Saint Elias (straddling the U.S. and Canada) is the only North America peak shown*, Denali must have been unknown to Hickmann. Here’s a detail with the Balkans in front and Amerika (mostly south and central) in the background. The second layer has the ocean depths with major seas layered on top of them, a clever way of showing many bodies of water in the same illustration. A second grouping underneath mirrors the top ones with a focus on the Alps atop the Mediterranean Sea and its affiliated bodies of water. Here’s a detail from the third and fourth panels with the Mediterranean and Ligurian Seas on the bottom, Bern on the foreground and some of the high peaks of the Alps in the background. *Not counting Hawaii as North America. Also Mt Hooker is a name that appears in many places but none of them are close to 4185 meters. For a deep dive into the rest of Hickmann’s atlas see Atilla’s post.
Adding a hillshade terrain to your basemap can give the map reader incredible amounts of information about the surface of the earth. But it’s also a mechanism for adding visual charm and interest to a map! With emotional resonance and technical merit bound up together in such a way, how can you possibly resist that …
Bert Spaan has taken Mapterhorn's global terrain data to create an interactive global Relief map. What is particularly interesting about this new map is that, unlike traditional topographic maps with a fixed colour-to-elevation scale, the map's colour spectrum adapts dynamically to the specific region or bounds currently in view. As you pan and zoom across different landscapes, the colour grading shifts to highlight local topographic variations, producing a striking and constantly changing view of the world's mountains, valleys and plains. This works particularly well when switching between very different environments: the colour range changes to bring out the relief at the scale you're viewing, rather than leaving low-lying terrain looking uniformly flat. A number of controls allow you to adjust how the elevation data is visualized. You can switch between absolute and visible elevation ranges, lock the current colour range, reverse the colours, animate the colours, and cycle through different ways of handling elevation outliers. You can also turn on hillshading, contours, labels and country borders, or switch to a 3D terrain view. Relief also includes a Seafloor option, which extends the elevation map beneath the oceans using GEBCO bathymetry. The result is a continuous view of the Earth's topography, from the deepest ocean trenches to the highest mountain peaks. At its core Relief is a WebGL-powered visualization of Mapterhorn's global elevation data that allows you to explore global topography at different resolutions and levels of detail.

I would like to direct my readers’ attention to a new Substack publication by Pete Morris called Terra Cognita. Pete is a frequent GeoCurrents commentor and an insightful geographer. His introductory article in Terra Cognita is an excellent overview of the recent history of academic geography in the United States. And as can be seen […] The post Recommending Terra Cognita, a New Geographical Substack Publication appeared first on GeoCurrents.
