Geophysics and Geodesy
Application of quantitative analysis based on gravity, thermal, magnetism, electromagnetic spectrum, reflection and refraction to determine the physical processes and properties of Earth constitutes Geophysics. In research this is mainly employed to foresee certain conditions based on these analyses.
Geodesy is a branch of mathematical science that is concerned with the shape and proportion of Earth, especially it’s geometric shape, orientation in space, and gravity field. It is highly resourceful in terms of mapping and GIS services.
