measure on outcrop
definition Orientation of surface or line is measured on an outcrop of that surface or line directly, e.g. by measuring a particular bedding surface, a 3-D exposure of a fold hinge, a particular stretched mineral grain in a foliation surface. more like this

visual surface estimation on outcrop
definition Orientation of a surface is measured by visually averaging across one or more outcrops in a small area--e.g. approximating dip by looking down strike of beds, approximating strike by outcrop trace of one or more beds. more like this
