The Vangarde system is researched, developed and patented by Longdin & Browning. It is known as the Clear Cone Surveying System in the UK and Europe. It enables a high precision survey of a highway surface which the Vangarde vehicle can complete while positioned on a highway hard shoulder, eliminating the need for lane closures.
Vangarde is a non-contact system. It is capable of measuring surface levels without physical contact with the survey point. Therefore the survey can be completed from the safety of the van.
Accurate pavement levels are observed through moving traffic. Points that are conventionally difficult to survey, such as bridge soffit levels, are now easily available.
Survey control is established at the same time as detail observations, making the system a ‘one-pass’ operation.
Information is presented in a format compatible with most CAD systems.
