'''Benchmark''' is a fixed point of reference used to locate a marked and recorded hazard or hazardous area. It should normally be located a short distance outside the hazardous area. It should be safe to walk from the Reference / Landmark to the Benchmark.
'''Evidence point''' may also be used for areas for recording of where mines/UXO were found. {{note| A benchmark may not be necessary if the reference point / landmark is sufficiently close to the perimeter of the hazardous area. There are also two point types that were used for LIS, View point and Start point.}}
==Polygon / polyline points for areas==__NOEDITSECTION__
'''Start Point''' is used as the name for the first Turning point in the polygon/polyline. Note that Start point may also been used as a single-point for Mined areas/SHA.
'''Datum Point''' has the same definition as Start point but is more unusual.
