Galactic Longitude
A measure of a star's position with respect to the Sun and Galactic center. Galactic longitude ranges from 0 degrees to 360 degrees.
Galactic Longitude - The angular distance, measured eastward around the galactic equator, from the galactic center to the point on the equator nearest the direction to a body

Galactic longitude is measured in degrees as well from 0° to 360° originating in the direction of the axial center of the Milky Way in the constellation Sagittarius.
Galactic latitude is designated b, galactic longitude l. The reference points for galactic coordinates were changed by action of the International Astronomical Union in 1958.

Using basic trigonometry, the distance of the fast moving gas (at ``A'') from the galactic center = (the Sun's distance)× sin[(galactic longitude)], ...
Galactic coordinates are expressed in terms of galactic latitude, bII, and galactic longitude, lII. The zero points of the galactic coordinate system expressed in the equatorial coordinate system are: α 17h 45.6m, δ -28° 56'.
With a galactic latitude of 3 degrees and galactic longitude 71 degrees,[2] this system lies inward along the same Orion Spur in which the Sun is located within the Milky Way,[40] near where the spur approaches the Sagittarius Arm.
The galactic system uses galactic latitude (glat) and galactic longitude (glon) to define the postion of objects in space relative to the galactic center (the center of our galaxy - the Milky Way). Galactic coordinates are measured in degrees.

Galactic coordinate system. Positions of objects are measured in terms of their galactic longitude( l ) and galactic latitude ( b ). The galactic equator slices the Galaxy in half (top and bottom).

Galactic Co-ordinates The system of celestial co-ordinates in which the galactic plane as the reference plane and the galactic centre as the reference direction. The positions are given in galactic latitude and galactic longitude.
