Each laser scan takes between 5 and 15 minutes, data capture is therefore very fast and accurate to millimeters. Traditional surveying is based on discrete data point observation, terrestrial laser scanning captures the complete asset. Thus, there is a significant improvement in the level of detail and accuracy of the raw data plus a more extensive range of possibilities for data analysis and use. The need for return to site visits are also reduced.
