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.

Aside from maps, I would say my next biggest obsession is coffee. For the last couple of months, my favourite bean, Finca La Bolsa, has been out of season and unavailable from my local roasters. I've therefore been using the opportunity to experiment with beans from different regions, different taste profiles and different processing methods. For some reason, it has only just dawned on me that there might be some coffee maps I can use to help me discover new beans to add to my coffee repertoire. Map of Coffee Origins & Flavors Lightyear Coffee has produced a number of data visualizations based on data collected from coffee roasters. These include a Map of Coffee Origins & Flavors, which shows the dominant flavour notes associated with beans from different countries. Using the map, you can select an individual country to explore the dominant tasting notes found in its coffee beans, or choose a particular flavour note to discover which countries produce coffees associated with that taste. Multiple Origin Multiple Origin is a personal project by Ahmad Merii that maps the information found on coffee bean packaging. The result is a world map of 318 specialty coffees from Merii's own collection, purchased and consumed between 2018 and 2026. The coffees are categorized by country and region of origin, variety, processing method, altitude, roast date, tasting notes and weight. Using the map, you can search for and filter coffees by roaster, processing method, variety and altitude. You can also explore a gallery of scanned coffee bags, with additional details available for each coffee. BeanMap BeanMap is a free, open-source atlas of specialty coffee that starts with an interactive 3D globe. It currently maps 55 coffee origins across 41 countries, with each origin accompanied by information about its altitude, processing method, harvest season and flavour profile. You can filter the map by region or flavour, or approach the data from the other direction using an interactive SCA flavour wheel. Click on a flavour such as jasmine or blackcurrant and the map filters down to coffees associated with that taste.
