Mapping archaeological digs takes plenty of time and a lot of measuring, photographing, drawing and note taking. Now, most of this work can be done with a technique called photogrammetry.
Photogrammetry is a method that uses two-dimensional images of an archaeological find to construct a 3D model.
You don't need and special glasses or advanced equipment to use make use of this new technique. Together with precise measurements of the excavation, photogrammetry can create a complete detailed map of an archaeological excavation site.
"This is still a very new technique," say archaeologists Raymond Sauvage and Fredrik Skoglund of the Norwegian University of Science and Technology's University Museum.
Photogrammetry is in many ways much more precise than older, more time-consuming methods.
