Longitude |
This field is derived from the expression...
BV.SURF_LONGITUDE + dsp.delta_x
...and consists of these database columns:
SURF_LONGITUDE - The longitude value of a location in a borehole. A positive value denotes east. Angle measured about the spheroid axis from a local prime meridian to the meridian through the point.
delta_x - Unknown

Latitude |
This field is derived from the expression...
BV.SURF_LATITUDE + dsp.delta_y
...and consists of these database columns:
SURF_LATITUDE - The latitude value of a location in the borehole. A positive value denotes north. Angle subtended with equatorial plane by a perpendicular from a point on the surface of a spheriod.
delta_y - Unknown
