Combined Graduated Level Examination (SSC CGL or CGLE) is an examination conducted by the Staff Selection Commission to recruit Group B and C officers to various posts in ministries, departments and organizations of the Government of India. The Staff Selection Commission was established in 1975.
The projection from spheroid to a UTM zone is some parameterization of the transverse Mercator projection. The parameters vary by nation or region or mapping system. Most zones in UTM span 6 degrees of longitude, and each has a designated central meridian. The scale factor at the central meridian is specified to be 0.9996 of true scale for most ...
The formulas involved can be complex and in some cases, such as in the ECEF to geodetic conversion above, the conversion has no closed-form solution and approximate methods must be used. References such as the DMA Technical Manual 8358.1 [15] and the USGS paper Map Projections: A Working Manual [16] contain formulas for conversion of map ...
ssc.gov.in Combined Higher Secondary Level Examination ( SSC CHSL ) is a standardized test conducted by the Staff Selection Commission (SSC) to recruit Lower Divisional Clerk (LDC)/ Junior Secretariat Assistant (JSA) / Postal Assistant and Data Entry Operator(DEO) officers to various posts in ministries, departments and organisations of the ...
The World Geodetic System (WGS) is a standard used in cartography, geodesy, and satellite navigation including GPS.The current version, WGS 84, defines an Earth-centered, Earth-fixed coordinate system and a geodetic datum, and also describes the associated Earth Gravitational Model (EGM) and World Magnetic Model (WMM).
The Earth-centered, Earth-fixed coordinate system (acronym ECEF), also known as the geocentric coordinate system, is a cartesian spatial reference system that represents locations in the vicinity of the Earth (including its surface, interior, atmosphere, and surrounding outer space) as X, Y, and Z measurements from its center of mass.
The commission is headed by a Chairman [5] and two members after him. Besides, there are one Secretary, one Director, one Deputy Secretary, two Joint Directors, nine Under Secretaries, four Deputy Directors, one Finance & Budget Officer, one Assistant Director (OL), 24 Section Officers and more than 183 supporting officers/staff are at the Headquarters for discharging the duties and ...
Formulas for the Web Mercator are fundamentally the same as for the standard spherical Mercator, but before applying zoom, the "world coordinates" are adjusted such that the upper left corner is (0, 0) and the lower right corner is ( , ): [7] = ⌊ (+) ⌋ = ⌊ ( [ (+)]) ⌋ where is the longitude in radians and is geodetic latitude in radians.
