Spatial Positioning

As all the data is collected by the one system all of the data sets provided are accurately co-located to less than one centimetre, thereby allowing correlations between surface, subsurface and surrounding features to be assessed.

The system also incorporates a high precision encoder, GPS and inertial measurement unit (IMU) to allow accurate geo-location of the data. This is then used to align to user provided chainage points or network spline data.
 

Case studies

A MS Word document summary report is produced to provide the following information:

 

  • Generalities of the data collected, information of how many lanes were scanned and starting and ending points of the scan (usually intersections);
  • Gazettal chainages or any other reference points used by the customers;
  • Description of the points used to align the data gathered according to the positioning system of the customer.
