Copernicus Sentinel vs GlobeViewer

The Sentinel App is a gateway to knowing the Copernicus Sentinel satellites. It lets users track the satellites in real-time, discover their key elements, read the latest news and learn more about their products. Users can, among other things, explore detailed 3D models of the satellites, see the last and next time they have been and will be over the user's location, move the satellites to the time of the last data transmission and smoothly move them back to their current location over the 3D globe. Notifications can also be set to be warned when the satellites are flying by. ESA is developing a series of next-generation Earth observation missions, on behalf of the joint ESA/European Commission initiative Copernicus (previously GMES - Global Monitoring for Environment and Security). The goal of the program is to replace current and older Earth observation missions, such as ERS and Envisat, which have reached or are close to reaching the end of their operational life span. This will ensure a continuity of data so that there are no gaps in ongoing studies. Each mission will focus on a different aspect of Earth observation, such as Atmospheric, Oceanic or Land monitoring, and the data will be of use in many applications.

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!
