title: Çatalhöyük - East Mound 2015

description: This collection includes a mixed remote sensing dataset made of terrestrial laser scanning point clouds, point cloud comparison data, structure from motion-generated polygonal meshes, and related textures and metadata. It was recorded at the Neolithic site of Çatalhöyük, Turkey under the Çatalhöyük Digital Preservation Project carried out in 2012-2017 by scholars and students from the University of California Merced and Cardiff University. The historic series of North Area and South Area point clouds were documented by means of a Faro Focus S120 time of flight laser scanning during six consecutive field seasons (2012-2017), while the East Mound and West Mound landscape 3-D models were generated from low-altitude photos captured by an unmanned aerial vehicle (drone) in 2015.

The goal of the Çatalhöyük Digital Preservation Project was to capture the current state of the site to comply with UNESCO site management guidelines for conservation and to understand and quantitatively assess the deterioration of its mud-brick architecture through time via 3-D data comparison and geo spatial methods. The analyses of laser scanning data focus on the wall features of eight buildings of the North Area (B5, B48, B49, B55, B64, B82, B114, B119), which were chosen as priority by Ashley Lingle, the Head of Conservation at Çatalhöyük. Point clouds of wall features were segmented and aligned using the open source software CloudCompare. Pairs of perfectly aligned and identically segmented point clouds were then compared using the M3C2 method in CloudCompare to compute differences (standard deviation) and significant change. The differences among aligned and identical features represent the material loss occurred in those walls in 2012-2017. The point clouds were then analyzed in a GIS platform including environmental data logged in the North Area and vulnerability assessment made in situ by the Conservation Team.
description: Çatalhöyük (Turkish pronunciation: also Çatal Höyük and Çatal Hüyük; from Turkish Çatal 'fork' + höyük 'tumulus') was a very large Neolithic and Chalcolithic proto-city settlement in southern Anatolia, which existed from approximately 7100 BC to 5700 BC, and flourished around 7000 BC.[2] In July 2012, it was inscribed as a UNESCO World Heritage Site.

Çatalhöyük is located overlooking the Konya Plain, southeast of the present-day city of Konya (ancient Iconium) in Turkey, approximately 140 km (87 mi) from the twin-coned volcano of Mount Hasan. The eastern settlement forms a mound which would have risen about 20 m (66 ft) above the plain at the time of the latest Neolithic occupation. There is also a smaller settlement mound to the west and a Byzantine settlement a few hundred meters to the east. The prehistoric mound settlements were abandoned before the Bronze Age. A channel of the ÇarÅŸamba River once flowed between the two mounds, and the settlement was built on alluvial clay which may have been favorable for early agriculture.
