TxDOT Survey Manual: Trigonometric Leveling

Differences in elevations are determined by measuring vertical angles and slope distances. Trigonometric leveling is often used where accurate elevations are not available or when elevation of inaccessible points must be determined. In Texas, most highway surveying does not require this type of leveling. Anchor: #i1053423.
