摘要： A surveying spike is described which includes a single nail portion and an end portion; the end portion is attached to the nail portion and coaxial therewith. The end portion has a body portion, and a reference surface forming portion projecting radially from the body portion and having a reference surface formed thereon parallel to the axis of the end portion. The reference surface has a dimple formed therein. When the surveying spike is driven into a vertical surface, the reference surface may then be horizontal and the dimple may receive a vertical pole; this facilitates surveying using EDM (electronic distance measurement) techniques. The surveying spike may advantageously be manufactured by providing a metal nail portion and a plastic end portion, and inserting the nail into the end portion.
