  2. Geographic coordinate conversion - Wikipedia

    en.wikipedia.org/wiki/Geographic_coordinate...

    In geodesy, conversion among different geographic coordinate systems is made necessary by the different geographic coordinate systems in use across the world and over time.

  3. Payroll - Wikipedia

    en.wikipedia.org/wiki/Payroll

    Payroll bureaus also produce reports for the businesses' account department and payslips for the employees and can also make the payments to the employees if required. As of 6 April 2016, umbrella companies are no longer able to offset travel and subsistence expenses and if they do, they will be deemed liable to reimburse HMRC any tax relief ...

  4. Universal Transverse Mercator coordinate system - Wikipedia

    en.wikipedia.org/wiki/Universal_Transverse...

    The Universal Transverse Mercator (UTM) is a map projection system for assigning coordinates to locations on the surface of the Earth. Like the traditional method of latitude and longitude , it is a horizontal position representation , which means it ignores altitude and treats the earth surface as a perfect ellipsoid .

  5. Military Grid Reference System - Wikipedia

    en.wikipedia.org/wiki/Military_Grid_Reference_System

    Near the equator, the columns of UTM zone 1 have the letters A–H, the columns of UTM zone 2 have the letters J–R (omitting O), and the columns of UTM zone 3 have the letters S–Z. At zone 4, the column letters start over from A, and so on around the world. For the row letters, there are actually two alternative lettering schemes within MGRS:

  6. Geographic coordinate system - Wikipedia

    en.wikipedia.org/wiki/Geographic_coordinate_system

    A geographic coordinate system (GCS) is a spherical or geodetic coordinate system for measuring and communicating positions directly on Earth as latitude and longitude. [1] It is the simplest, oldest and most widely used type of the various spatial reference systems that are in use, and forms the basis for most others.

  7. Universal polar stereographic coordinate system - Wikipedia

    en.wikipedia.org/wiki/Universal_Polar...

    The universal polar stereographic (UPS) coordinate system is used in conjunction with the universal transverse Mercator (UTM) coordinate system to locate positions on the surface of the Earth. Like the UTM coordinate system, the UPS coordinate system uses a metric-based cartesian grid laid out on a conformally projected surface.

  8. Web Mercator projection - Wikipedia

    en.wikipedia.org/wiki/Web_Mercator_projection

    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.

  9. Coordinate system - Wikipedia

    en.wikipedia.org/wiki/Coordinate_system

    It assigns three numbers (known as coordinates) to every point in Euclidean space: radial distance r, polar angle θ , and azimuthal angle φ . The symbol ρ ( rho ) is often used instead of r . In geometry , a coordinate system is a system that uses one or more numbers , or coordinates , to uniquely determine the position of the points or ...
