Although not in standard, most DBMS allows using a select clause without a table by pretending that an imaginary table with one row is used. This is mainly used to perform calculations where a table is not needed. The SELECT clause specifies a list of properties (columns) by name, or the wildcard character (“*”) to mean “all properties”.
SMS-derived GOES satellite This is a list of Geostationary Operational Environmental Satellites . GOES spacecraft are operated by the United States National Oceanic and Atmospheric Administration , with NASA responsible for research and development, and later procurement of spacecraft.
A derived table is the use of referencing an SQL subquery in a FROM clause. Essentially, the derived table is a subquery that can be selected from or joined to. The derived table functionality allows the user to reference the subquery as a table. The derived table is sometimes referred to as an inline view or a subselect.
On 25 May 2017, NOAA announced that GOES-16 would occupy the GOES East position once operational, succeeding GOES-13. [98] GOES-16's move to its operational position began at around 13:30 UTC on 30 November 2017, drifting about 1.41° per day to a final longitude of 75.2°W; during this time, the spacecraft's instruments were kept in a ...
A compass rose or compass star, sometimes called a wind rose or rose of the winds, is a polar diagram displaying the orientation of the cardinal directions (north, east, south, and west) and their intermediate points. It is used on compasses (including magnetic ones), maps (such as compass rose networks), or monuments.
Direction determination refers to the ways in which a cardinal direction or compass point can be determined in navigation and wayfinding.The most direct method is using a compass (magnetic compass or gyrocompass), but indirect methods exist, based on the Sun path (unaided or by using a watch or sundial), the stars, and satellite navigation.
The GOES-13 GVAR and (Low Rate Information Transmission) LRIT were relayed through GOES-14 until 8 January 2018, at which time the GOES-13 GVAR relay through GOES-14 GVAR was disabled. GOES-13 ceased transmitting data, began drifting to its storage location at 60.0° West on 9 January 2018, and arrived there on 31 January 2018. [19] GOES-13 ...
GOES-17 has the same instruments and capabilities as GOES-16 (currently serving as GOES-East), and will complement its work by scanning a different area of the world. GOES-17 is GOES-West when it moves to 137.2° West longitude and cover the west coast of the continental U.S. , Hawaii , and much of the Pacific Ocean .
