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. To see some of the most beautiful highlights of this data click on the ‘Explore‘ button in the map’s menu bar.
