Relationships with occupations

Essential knowledge

Geodesy is an essential knowledge of the following occupations:

Hydrographic surveyor: Hydrographic surveyors measure and map, by means of specialised equipment, marine environments. They collect scientific data in order to study the underwater topography and morphology of bodies of water.
Surveying technician: Surveying technicians carry out technical surveying tasks. They assist surveyors, architects or engineers in surveying related technical tasks such as mapping land, creating construction drawings and operating precise measuring equipment
Hydrographic surveying technician: Hydrographic surveying technicians perform oceanographic and surveying operations in marine environments. They assist hydrographic surveyors, using specialised equipment to map and study underwater topography and morphology of bodies of water. They assist in the installation and deployment of hydrographic and surveying equipment and report about their work.
Remote sensing technician: Remote sensing technicians collect airborne data. They utilise equipment aimed for the collection of data and determination of geographical points in order to help in a variety of operations such as land conservation, urban planning, and military operations.
Land surveyor: Land surveyors determine, by means of specialised equipment, the distances and positions of points at the surface of sites for construction purposes. They use measurements of the specific aspects of construction sites, such as electricity, distance measurements, and metal structure volumes to create architectural drawings and develop construction projects.

Optional knowledge

Geodesy is optional for these occupations. This means knowing this knowledge may be an asset for career advancement if you are in one of these occupations.

Land planner: Land planners visit sites in order to create projects and plans for land usage and development. They collect and analyse data about the land. Land planners provide advice on the efficiency and safety of development plans.
Mineralogist: Mineralogists study the composition, structure and other physical aspects of the earth. They analyse various minerals and use scientific equipment to determine their structure and properties. Their work mostly focuses on the classification and identification of minerals by taking samples and performing further tests, analysis and examinations.
Geographic information systems specialist: Geographic information systems specialists use specialised computer systems, engineering measures, and geological concepts to process land, geographic, and geospatial information into visually detailed digital maps and geomodels of a reservoir. They convert technical information like soil density and properties into digital representations of it for the usage of engineers, governments, and stakeholders interested.
Cartographer: Cartographers create maps by combining various scientific informations depending of the purpose of the map (e.g. topographic, urban, or political maps). They combine the interpretation of mathematical notes and measurements with the aesthetics and visual depiction of the site for developing the maps. They may also work on developing and improving geographic information systems and may perform scientific research within cartography.
Civil engineer: Civil engineers design, plan, and develop technical and engineering specifications for infrastructure and construction projects. They apply engineering knowledge in a vast array of projects, from the construction of infrastructure for transportation, housing projects, and luxury buildings, to the construction of natural sites. They design plans that seek to optimise materials and integrate specifications and resource allocation within the time constraints.
Geology technician: Geology technicians assist in all the activities carried out by geologists. They, under the supervision of geologists, collect materials, carry out research and study the samples collected from the Earth in order to offer analysis as part of the project and the aim. Geology technicians assist in determining the value of the land for oil or gas exploration. They perform various technical tasks, including collecting samples during geochemical surveys, working on drill sites, and participating in geophysical surveys and geological studies.
