What is declination in survey?
The difference between true north and magnetic north is called declination. Declination varies from place to place and from year to year. This reorients the survey to the declination. For example, if a map shows the declination to be 13 degrees, it means that Magnetic North is 13 degrees to the east of True North.
What is right ascension in survey?
Right ascension (abbreviated RA; symbol α) is the angular distance of a particular point measured eastward along the celestial equator from the Sun at the March equinox to the (hour circle of the) point in question above the earth.
Is right ascension latitude or longitude?
Right ascension (RA) is the celestial equivalent of longitude. RA can be expressed in degrees, but it is more common to specify it in hours, minutes, and seconds of time: the sky appears to turn 360° in 24 hours, or 15° in one hour. So an hour of RA equals 15° of sky rotation.
