The Excavation plan

The actual grid is reproduced on paper, e.g. every object is drawn in exactly the same position that it was found in. Objects retrieved have a label from which their position, orientation and elevation is noted. For objects that cannot be brought to the surface, or naval structures, the method of triangulation is used: three posts, or base points, are precisely measured by GPS. From there a decametre is extended towards the point to be measured, and the data noted. The three measurements should then on paper intersect and thus pinpoint the location of the object in question.

The excavation plan is built up day by day, until a complete picture of the archaeological site emerges. Only then the site can be interpreted.
