Geographic coordinate conversion has applications in cartography, surveying, navigation and geographic information systems. In geodesy, geographic coordinate conversion is defined as translation among different coordinate formats or map projections all referenced to the same geodetic datum. [1] A geographic coordinate transformation is a ...
Unit of time. A unit of time is any particular time interval, used as a standard way of measuring or expressing duration. The base unit of time in the International System of Units (SI), and by extension most of the Western world, is the second, defined as about 9 billion oscillations of the caesium atom. The exact modern SI definition is ...
SMPTE timecode (/ ˈsɪmptiː / or / ˈsɪmtiː /) is a set of cooperating standards to label individual frames of video or film with a timecode. The system is defined by the Society of Motion Picture and Television Engineers in the SMPTE 12M specification. SMPTE revised the standard in 2008, turning it into a two-part document: SMPTE 12M-1 and ...
Angles in the hours ( h), minutes ( m), and seconds ( s) of time measure must be converted to decimal degrees or radians before calculations are performed. 1 h = 15°; 1 m = 15′; 1 s = 15″ Angles greater than 360° (2 π ) or less than 0° may need to be reduced to the range 0°−360° (0–2 π ) depending upon the particular calculating ...
At its native 24 FPS rate, film could not be displayed on 60 Hz video without the necessary pulldown process, often leading to "judder": To convert 24 frames per second into 60 frames per second, every odd frame is repeated, playing twice, while every even frame is tripled. This creates uneven motion, appearing stroboscopic.
The large dial shows the ten hours of the decimal day in Arabic numerals, while the small dial shows the two 12-hour periods of the standard 24-hour day in Roman numerals. Decimal time is the representation of the time of day using units which are decimally related. This term is often used specifically to refer to the French Republican calendar ...
Time is given in units of hours, minutes, seconds, and frames. There may be 24, 25, or 30 frames per second. Unlike most other timecodes, the components are encoded in straight binary, not binary-coded decimal. Each component is assigned one byte: Byte 0 0rrhhhhh: Rate (0–3) and hour (0–23). rr = 00: 24 frames/s; rr = 01: 25 frames/s
A right-handed convention, specifying a y axis 90° to the east in the fundamental plane and a z axis along Earth 's north polar axis. This frame is similar to the ξ, η, ζ frame above, except that the origin is removed to the centre of the Sun. It is commonly used in planetary orbit calculation.
