2. FIELDWORK RESULTS TOPOGRAPHIC SURVEY Oscar Aldred, FSÍ A contour survey was carried out over 3 days, between 19th and 21st June, <strong>2002</strong> in the area immediately south and west of the main excavation area. The survey area covered c. 17,520 square metres, with a perimeter of c. 0.65 km. Objectives The initial ground truthing of the survey area showed there to be several earthwork features, ranging in extent from 2-3 metres to over 100 metres in length. There was also 28 metres range in the height; c. 59 metres to c. 77 metres. As a result it was decided to set the resolution of the survey at 5 metres. The objectives of the <strong>2002</strong> season were to: 1. To obtain a coarse resolution contour survey of the area at approximately 5m resolution; 2. To identify areas for targeted survey in the following season. Methodology The survey was carried out using 2 Trimble 4600LS GPS units to track GPS satellites on the L1 frequency. A TDC1 Survey Controller was used. A Base Station Receiver was set up over a free station point (i.e. not known) and was initialised with the Rover. The poisiton of the Base Station Receiver was calibrated. The accuracy of the survey x, y, z was to +-1 m. 7

Post survey processing was carried using GPSurvey 2.35 to calculate baselines and recalibration of the height with respect to the NKG96 Geoid Iceland. WGS84 datum and Geodetic format was used and converted to ISN93 local coordinate system. Image processing of the data was carried out in Surfer8. Nearest Neighbour interpolation was used to construct the 3D model using Anisotropy Ratio of 1 and Anisotropy Angle of 0 and a spacing of 2.12 (Grid report can be found in the SKH02 archive). The data collection was divided into 3, each area demarcating natural limits within the survey. The 1st area, East, covered 5,460 square metres was traversed in a systematic north-south direction at 5 metres transect intervals. The 2nd area, West, covered 4,350 square metres in a systematic east-west direction at 5 metres transect intervals. The 3rd area, South-west, covered 7,710 square metres in a systematic east-west direction at 5 metres transect intervals. 8
