At the ancient Site of Troizen, Peloponnes, Greece

On the 14th of April I started from Heidelberg with three colleagues to do fieldwork on the Peloponnes, Greece. The tour is separated in two parts: The first is archaeological documentation at Troizen (also known as Troezen or Trizina) while the second is to support the laserscanning fieldschool at Kalavryta organized by the LiDAR Research Group of the Geography department.

I’m involved to the Troizen Archaeology Project since it’s start in 2012 with a first survey campaign, where we tried to get as much informations about the ancient city and acropolis with the GNSS and also did a couple of 3D models of the so called “Frankish Tower” and some very well preserved roman tombs. The second visit was of very technical nature. I could manage to start a collaboration of the Institute for Classical Archaeology and the LiDAR Research Group. It was important for the project because it was possible to bring a long range laserscanner to Troizen, a Riegl VZ-6000, a unique chance to acquire the whole area of the city, the acropolis and also the surroundings in a radius of six kilometres. And this was not the only highlight – we also had a UAV from Swiss company SenseFly, the eBee, equiped with a common RGB-camera but also a multispectral camera. As tiny the bee is, as large is the area it can cover. Impressive. And last not least we had the ArchEyeAutomatic UAVs with us to complete the 3D models of the objects around but also to do some more detailed photos in several areas.

Several days, scans and flights later, we do have a lot of new data waiting for the processing and evaluation.


A hint for people visiting Poros – we were accommodated there – and like to have good and substantial food: Go to Apagio Taverna! Spyros, the host, is very nice and recommends you always excellent food.
