    The coordinate format can be chosen via Tools → Options → 3D View → Show Lat/Long. There are many ways to obtain coordinates: Move the mouse pointer to where you want, then use the keyboard to select the Menu item Edit → Copy View Location to copy the coordinates to the clipboard. More convenient is the associated keyboard shortcut.

  3. Earth-centered, Earth-fixed coordinate system - Wikipedia

    en.wikipedia.org/wiki/Earth-centered,_Earth...

    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.

    Moves all windows off the screen, with just the edges of the windows visible at the side of the screen, giving the user clear access to the desktop and any icons on it. This can be activated by pressing Command F3 on newer Apple aluminum and Macbook keyboards, the F11 key on older keyboards. On a trackpad, it can be selected by placing four ...

  6. Decimal degrees - Wikipedia

    en.wikipedia.org/wiki/Decimal_degrees

    Decimal degrees (DD) is a notation for expressing latitude and longitude geographic coordinates as decimal fractions of a degree.DD are used in many geographic information systems (GIS), web mapping applications such as OpenStreetMap, and GPS devices.

  7. Geodetic coordinates - Wikipedia

    en.wikipedia.org/wiki/Geodetic_coordinates

    Geodetic latitude and geocentric latitude have different definitions. Geodetic latitude is defined as the angle between the equatorial plane and the surface normal at a point on the ellipsoid, whereas geocentric latitude is defined as the angle between the equatorial plane and a radial line connecting the centre of the ellipsoid to a point on the surface (see figure).

  8. Spatial reference system - Wikipedia

    en.wikipedia.org/wiki/Spatial_reference_system

    A spatial reference system (SRS) or coordinate reference system (CRS) is a framework used to precisely measure locations on the surface of Earth as coordinates. It is thus the application of the abstract mathematics of coordinate systems and analytic geometry to geographic space.

  9. State Plane Coordinate System - Wikipedia

    en.wikipedia.org/wiki/State_Plane_Coordinate_System

    Thus the state plane coordinate system is still useful. Originally, the state plane coordinate systems were based on the North American Datum of 1927 (NAD27). Later, the more accurate North American Datum of 1983 (NAD83) became the standard (a geodetic datum is the way a coordinate system is linked to the physical Earth). More recently there ...
