The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording in the performance criteria is detailed below. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts. |

Geodetic components may include: | geodetic control: a network of sites for which precise positions and heights are known and for which the shape and size of the earth are taken into account geodetic latitude: the smaller angle to the earth’s ellipsoid at the point and the plane of the equator geodetic parameters other information required on the relevant surface or projection plane. |
Survey control may include: | measurement of temperature and pressure measurement of main traverse lines with EDM instrument specification of critical length of traverse line specification of pointings to be observed for vertical angles along main traverse lines and for radiations use of direction method to observe main traverse angles and radiations use of theodolite and direction method of angle observation. |
Precise traverse may include: | computation of three-dimensional coordinates and coordinate changes by intersection methods error analysis of survey measurements (angle, distance and height difference). |
