To draw the maps the Speleo-Vulcain group from France is using Visual Topo for simple systems. However, because of the difficulties to build a rigorous synthesis and to update the survey of the complex Jean-Bernard System, they passed to the open source software Therion.
The VST dome among VLT's telescopes. It is located in the background between two of the VLT auxiliary telescopes (small round enclosures). The VST is an alt-azimuthal wide-field survey telescope with a primary mirror diameter of 2.65 meters that was constructed from 2007 to 2011 at the ESO Cerro Paranal Observatory, in Chile.
These are among the best locations for astronomical observations in the southern hemisphere. [21] An ESO project is the Extremely Large Telescope (ELT), a 40-metre-class telescope based on a five-mirror design and the formerly planned Overwhelmingly Large Telescope. The ELT will be the largest visible and near-infrared telescope in the world.
OpenStreetMap (abbreviated OSM) is a free, open map database updated and maintained by a community of volunteers via open collaboration. [4] Contributors collect data from surveys, trace from aerial photo imagery or satellite imagery, and import from other freely licensed geodata sources.
Some of the free software mentioned here does not have detailed maps (or maps at all) or the ability to follow streets or type in street names (no geocoding). However, in many cases, it is also that which makes the program free (and sometimes open source [ 1 ] ), avoid the need of an Internet connection, [ 2 ] [ 3 ] [ 4 ] and make it very ...
[10] [11] [12] Red band sources for the southern sky include the short red (SR) plates of the SERC I/SR Survey and Atlas of the Milky Way and Magellanic Clouds (referred to as AAO-SR in DSS2), [13] the Equatorial Red (SERC-ER), [5] and the F-band Second Epoch Survey (referred to as AAO-SES in DSS2, AAO-R in the original literature), [14] all ...
From an aerial view of the Paranal Observatory, the four large units of the VLT with their four small, dome-shaped auxiliary telescopes can be clearly seen. The Survey Telescope, VST, is immediately adjacent to the VLT and seen in between two of its units, while VISTA is located on a secondary peak, some 1,500 m away in the background (see image).
Bing Maps (previously Live Search Maps, Windows Live Maps, Windows Live Local, and MSN Virtual Earth) is a web mapping service provided as a part of Microsoft's Bing suite of search engines and powered by the Bing Maps Platform framework which also support Bing Maps for Enterprise APIs and Azure Maps APIs.
