Highway surveying issues
Based on our experiences combining survey methods to suit a particular client’s need. We have recently turned our attention to remotely surveying highway sections to the highest possible accuracy.
Whilst several high-speed, dynamically positioned approaches have been developed, level accuracy is the limiting factor to the survey data’s usefulness. Although significant lengths of highway can be recorded in very short periods, level accuracies are limited to typically 2 to 3cm compared to traditional survey methods.
