The 2022 ETOPO version is the most recent global relief model with several scans at 1 arc-min, 30 arc-sec, and 15 arc-sec resolutions. [1] The ETOPO Global Relief Model combines topographic, bathymetric, and shoreline data from regional and global sources to provide high-resolution representations of Earth's surface.
With the rapid development of this technology its use is becoming increasingly economic. In order to create a raised-relief map using a 3D printer, Digital Elevation Models (DEM) are rendered into a 3D computer model, which can then be sent to a 3D printer. Most consumer-level 3D printers extrude plastic layer by layer to create a 3D object.
NASA WorldWind is an open-source (released under the NOSA license and the Apache 2.0 license) virtual globe. According to the website, "WorldWind is an open source virtual globe API. WorldWind allows developers to quickly and easily create interactive visualizations of 3D globe, map and geographical information.
NASA WorldWind, an open-source virtual globe with stars and advanced atmosphere and sunlight effects. A virtual globe is a three-dimensional (3D) software model or representation of Earth or another world. A virtual globe provides the user with the ability to freely move around in the virtual environment by changing the viewing angle and position.
3D rendering of a DTM of Tithonium Chasma on Mars. A digital elevation model (DEM) or digital surface model (DSM) is a 3D computer graphics representation of elevation data to represent terrain or overlaying objects, commonly of a planet, moon, or asteroid. A "global DEM" refers to a discrete global grid.
Upright=1.3STL 3D model of Penang Island terrain based on ASTER Global DEM data. Terrain rendering covers a variety of methods of depicting real-world or imaginary world surfaces. Most common terrain rendering is the depiction of Earth's surface. It is used in various applications to give an observer a frame of reference.
Earth3D was developed as part of a diploma thesis of Dominique Andre Gunia at Braunschweig University of Technology [1] to display a virtual globe of the earth. It was developed before Google bought Keyhole, Inc and changed their product into Google Earth. Earth3D downloads its data (satellite imagery and height data) from a server while the ...
Topographic view of Earth relative to Earth's center (instead of to mean sea level, as in common topographic maps) By the late 1600s, serious effort was devoted to modeling the Earth as an ellipsoid, beginning with French astronomer Jean Picard's measurement of a degree of arc along the Paris meridian. Improved maps and better measurement of ...
