Highway surveying issues

Based on our experiences of combining survey methods to suit a particular client need, we have most recently turned our attentions to the problem of remotely surveying sections of highway to the highest possible accuracy.

Whilst a number of high speed, dynamically positioned approaches have been developed, the limiting factor upon the survey datas' usefulness has been that of level accuracy and although significant lengths of highway can be recorded in very short periods of time, level accuracies are limited to typically 2 to 3cm when compared to traditional survey methods.

Mobile mapping

Currently, our approach is Mobile Mapping to achieve typically 4mm repeatability, which is similar to traditional survey methods, but due to the intense coverage of the scanned carriageway, smaller localised level problems are more easily identified, can be accurately quantified, and monitored to isolate developing problems.
