GlobeViewer vs Terra

GlobeViewer is a high resolution 3D terrestrial globe with topography and surface maps. This app enables a high-quality view of the surface of our blue planet. It is divided into two areas: the rotatable, global view as an interactive globe and a high-resolution 3D map representation of the Earth's topography. - Interactive 3D globe with surface, underwater and topography maps - High-resolution 3D topography map set of the entire Earth's surface - divided into 22,912 individual tiles. You can load 110 different regions onto the interactive globe, which then present the many individual tiles in a meaningful, connected way and reload them automatically. The app initially only contains the textures for the globe in low resolution. All required downloads are automatically loaded from our server. A total of around 105 GB of data is available. The data remains in the cache on your device for offline use, but can be deleted at any time in the main menu. Furthermore, all events recorded by the GDACS, such as hurricanes, earthquakes, etc., are entered on the globe. The 3D topography map is based on the elevation data from the NASA Terra probe, which recorded 83° of the northern and southern hemispheres between 2000 and 2013 - this is the result of the ASTER3-DEM. With version 0.10.0, the map is enriched with around 7.5 million place names from geonames.org. This means that all the towns, mountains, lakes, deserts and many other geographical features entered there are shown on the map. From version 0.12.0, data from OpenStreetMaps (buildings, borders, streets...) is also available on the tiles - but only for the demos and the purchased maps. Use the tutorial in the app to get started quickly or read the manual to find out which functions are included in this app. Since the app is still under development, some functions may still change. We hope you enjoy using GlobeViewer!

Global design of the NASA Terra satellite, represented along with its equipment and some data products. The application allows the user to interact with a 3D model of the NASA Terra satellite in order to learn the way it works, the payload and equipment present in the system, and the kind of data the satellite obtains to perform detailed observations of the Earth. Very useful to introduce in satellite development and EOS missions. The application is composed of the following interactive sections: * Flyby: Simulation of the overpass of the satellite. Time, distance and size proportions are completely real. The scene does not show the real position of the satellite. Actually, it will appear in a different and random part of the globe every time the scene is loaded. * Terra: 3D visualization of the satellite, where each instrument can be selected to get complete information about it. * MODIS: Simple 3D visualization of the Terra MODIS instrument, where every component has been identified. * Products: Visualization of processed data acquired by the Terra ASTER instrument. The area belongs to Monfragüe National Park (Spain), and it can be observed using different band combinations, which allow to highlight certain characteristics. The scene also presents a simulation of an user login procedure to download the original satellite products. NOTE: This is NOT an official NASA application. All the information has been collected from official publications. CREDITS: The original Terra mission is currently being developed by NASA. This institution owns the rights over the official and original design of the satellite, payload and data product types. The 3D adaptation of the satellite has been performed using official NASA sources and belongs to Himalaya Computing. The Milky Way background was generated by ESO.
