ROCK ARMOUR STOCKPILE
To help plan the rate at which rock armour could be placed it was necessary to get accurate data.
A walk over topographic survey would be risky to undertake. A trip or slip on the rocks could result in physical harm to staff and damage to expensive equipment.
Photogrammetry can create a 3d model that can be examined to determine volumes. It is quicker, safer and more accurate than conventional methods.
