  • underwater survey;
  • first step in survey - creating sketch of site, basis for any future work;
  • site work – planning well before beginning work is efficient, safe and problem free;
  • setting up a baseline/control points - surveying work out position of survey point from other points;
  • installing survey points;
  • offsets - measurements positioning features relative to tape baseline fixed between two control points;
  • principles of survey - depicting features in symbolic way, and showing three-dimensional relationships between them;
  • ties/trilateration - creating triangle, taking two measurements from feature to two chosen points on baseline;
  • survey using tape-measures, grids and drafting film;
  • three-dimensional computer-based survey
