SMR No.: KE104A001039-
Monument Type: Monastery
The Monastery consists of an inner stone enclosure with two oratories, a mortared church, seven cells (five of which are intact) and the remains of a beehive toilet, water cisterns, a cemetery, leachta (possible cult shrines or pilgrim stations), crosses and cross-slabs. It also includes two large terraces referred to as the Upper and Lower Monks’ Gardens. High retaining walls support all the terracing, upon which everything is constructed.

3D Capture Method 1: Aerial Lidar
3D Capture Description: FLI-MAP 400; an aerial LiDAR survey system, was initially designed to survey infrastructural assets such as roads, railways and electricity supply networks. The sensor system mounted beneath the main helicopter fuselage consists of:
- Three 150 kHz LiDAR sensors (7◦ forward, nadir and 7◦ aft);
- Scanning angle 60◦
- Accuracy (relative) Horizontal 5 cm, Vertical 3 cm
- Multiple returns 4
- Two RTK GPS receivers – provide accurate location in used in conjunction with RTK base stations;
- Inertial Navigation System (INS)- continuously track the position, orientation, and velocity of the helicopter;
- Digital imaging (11 megapixel) and digital video capture.
Resulting data sets include first return (DSM) and last return point (DTM, bare earth) models
Data Processing Software: ArcGIS & Geomagic Studio
3D Capture Method 2: Terrestrial laser scanning (TLS)
3D Capture Description: Phase based terrestrial laser scanning using a Faro Focus 120 laser scanner. The instrument quotes the following specification:
- Distance accuracy up to ±2mm.
- Range from 0.6m up to 120m.
- Measurement rate up to 976,000 points/sec.
- Intensity & RGB. Integrated colour camera.
- Photorealistic 3D colour scans with up to 70 megapixels.
- Parallax-free colour overlay.
Laser scans geo-referenced using RTK GPS with VRSnow corrections
