The campaign, which completed at least 22,000 laser scans was carried out by two teams each composed of three field operators.
The scans were carried out considering a workable range up to 12m. This ensured coverage of the cone of shadow for each scan, equal to 2m radius at a height of 1.75m (the area in which multiple scans overlap contains the cones of shadow of the others).
Each scan detected at least 6 target in all, three with the earlier scan and three with the following scan. The targets are square in shape, measuring5x5cm.
