6 competencescartography
The study of interpreting the elements depicted in maps, the measures and technical specifications.
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.
green
hydrology
The study of the water concerning the availability and movement of water as well as the impact of human activities on the water cycle.
- Scope note
- Excludes the study of groundwater, which is the focus of hydrogeology.
surveying methods
The fundamental principles and procedures of surveying applied to civil engineering, including remote sensing methods, and related equipment.
topography
Graphic representation of the surface features of a place or region on a map indicating their relative positions and elevations.
Cross-sector
4 competencesgeodesy
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.
geomatics
The scientific discipline that studies gathering, storing, and processing geographic information.
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.
surveying
The technique of determining the terrestrial or three-dimensional position of points and the distances and angles between them.
