The MESSENGER mission has released the first global digital elevation model (DEM) of Mercury, revealing in stunning detail the topography across the entire innermost planet and paving the way for ...

Figure 6: Viscosity, velocity and density structure of mantle. We present a new and comprehensive global database of oceanic residual depth measurements which was carefully constructed by analysing ...

PlanetObserver has released PlanetDEM, its new global Digital Elevation Model (DEM) with a 30m and a 90m resolution. This new DEM offers an updated, reliable, and homogeneous 3D dataset of the entire ...

The most complete digital topographic ever made of the Earth was released by NASA Monday. The map, known as a global digital elevation model, was created from images collected by the Japanese Advanced ...

New research by a team that included a Johns Hopkins engineer promises to enable more accurate ice-flow predictions, helping scientists better forecast how melting glaciers will contribute to rising ...

NASA and Japan released a new digital topographic map of Earth Monday that covers more of our planet than ever before. The map was produced with detailed measurements from NASA’s Terra spacecraft. The ...

Rising mountains do more than reshape the landscape – they also drive evolutionary change, according to a new study. By simulating millions of years of tectonic uplift, researchers have uncovered a ...

A floodplain map has three key components: base map imagery and/or cartographic line work, an elevation model representing the earth’s surface or “terrain,” and flood study results generated from ...

Given the critical issues that are arising as a direct result of climate change, the need to monitor the status of our environment is self-evident. One key parameter in monitoring climate change is ...
