Restrictions due to safety and access can cause problems and delays with traditional surveying techniques. One crucial advantage of laser scanning is that you never have to set foot on to the target scan area. Such a benefit is vital when considering the recording of a high volume traffic environment or a road traffic accident scene. As is often the case with restricted access sites, it is very important to ensure that everything is recorded on the first visit as this is often the only chance to gather data. The laser scanner has the ability to do this, and with the combination of high resolution images overlaid on the data additional peace of mind is assured.
