A line indicating a series of positions at which the observer is estimated to be at the time of observation. These can be straight, curved, hemispherical, or irregular lines, depending on the information they convey. Circular position lines indicate range (e.g., visual range, radar range, hyperbolic position lines), whereas straight lines represent an angular relationship between an aircraft and a known position or orientation of a tall ground or high feature.
