Personality Type

  • Realistic / Investigative
  • Investigative / Conventional

Knowledge

  • Mathematics

    Mathematics is the study of topics such as quantity, structure, space, and change. It involves the identification of patterns and formulating new conjectures based on them. Mathematicians strive to prove the truth or falsity of these conjectures. There are many fields of mathematics, some of which are widely used for practical applications.

  • Topography

    Graphic representation of the surface features of a place or region on a map indicating their relative positions and elevations.

  • Geodesy

    The scientific discipline that combines applied mathematics and earth sciences in order to measure and represent the Earth. It studies phenomena such as gravitational fields, polar motion, and tides.

  • Cartography

    The study of interpreting the elements depicted in maps, the measures and technical specifications. 

  • Surveying methods

    Have an understanding of surveying methods, remote sensing methods and equipment.

  • Geomatics

    The scientific discipline that studies gathering, storing, and processing geographic information.

  • Hydrography

    The scientific discipline that studies and measures the physical features of bodies of water such as oceans, lakes and rivers. It studies the current situation for navigational purposes and predicts change over time.

  • Surveying

    The technique of determining the terrestrial or three-dimensional position of points and the distances and angles between them.

  • Bathymetry

    The scientific discipline that studies underwater topography.

Skills

  • Operate surveying instruments

    Operate and adjust measuring instruments such as theodolites and prisms, and other electronic distance-measuring tools.

  • Prepare surveying report

    Write a survey report containing information on property boundaries, the height and depth of the terrain, etc..

  • Conduct underwater surveys

    Conduct subaquatic surveys to measure and map the underwater topography and morphology of bodies of water in order to aid the planning of aquaculture projects, the construction of marine constructions, and the exploration of natural resources.

  • Record survey measurements

    Gather and process descriptive data by using documents such as sketches, drawings and notes.

  • Calibrate electronic instruments

    Correct and adjust the reliability of an electronic instrument by measuring output and comparing results with the data of a reference device or a set of standardised results. This is done in regular intervals which are set by the manufacturer and using calibration devices.

  • Adjust surveying equipment

    Ensure accuracy of measurement by adjusting surveying equipment.

  • Perform surveying calculations

    Perform calculations and gather technical data in order to determine earth curvature corrections, traverse adjustments and closures, level runs, azimuths, marker placements, etc.

  • Collect mapping data

    Collect and conserve mapping resources and mapping data.

  • Document survey operations

    Complete and file all required administrative, operational and technical documents related to a survey operation.

  • Compare survey computations

    Determine the accuracy of data by comparing computations with applicable standards.
