Skellig Monastery INTROnewSMR 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.

Technical Details

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
