About Geodesy
The study of geometrical and gravitational properties of the earth and their changes during the time is literally known as Geodesy. It also studies physical components of the earth such as hydrosphere, atmosphere and the earth core.
The major objectives of the geodesy are as follows:
- Determination of the shape of the earth and its gravitation and changes in them. This results in monitoring of crustal and polar motion.
- Definition of a geodetic coordinates system in order to determination horizontal and vertical networks precise coordinates.
- Exploiting different geodetic instruments and techniques including total stations, GNSS, VLBI, etc. to measure distance directions and baselines precisely.
- Presentation of mathematical models to be used for geodetic coordinates and map projection
Geodesy can be divided into the following branches:
1. Geophysical Geodesy: techniques used to model and study geodynamical process including crustal movements, galical isostatic adjustment and variations in Earth rotation and orientation.
2. Physical Geodesy: determination of the Earth's physical shape and its gravitational field by formulation and solution of the relevant boundary-value problems, is the major concern of this branch.
3. Geometrical/Mathematical Geodesy: This branch leads with computing accurate position from geodetic measurements, mostly on reference ellipsoid, map projection is classified as a task of this branch as well..
3. Satellite/Space Geodesy: It's tasks include precise orbit determination (hence inferring the gravity field and also terrestrial and space positioning using range measurements.
4. Astronomical Geodesy: This branch is concerned with development of astronomical theories and techniques to define and estimate the shape of the earth and its gravitational field.
5- Astronomical Geodesy: This branch is concerned with development of astronomical theories and techniques to define and estimate the shape of the earth and its gravitational field.

Introduction to Surveying Engineering - Geodesy
Geodesy is the science of measuring and representing the Earth's surface. It serves as the foundation for location-based sciences and surveying, focusing on the Earth's geometric, structural, and gravitational characteristics, as well as their temporal changes. Geodesy also studies the dynamic interactions of the Earth with other physical components of the Earth's system, such as the atmosphere, hydrosphere, cryosphere, and core, across large spatial and temporal scales.

Introduction to Surveying Engineering - Hydrography
Hydrography is a branch of geodesy that deals with the observation and description of the characteristics of oceans, seas, coastal areas, lakes, and rivers, as well as predicting their changes. The goal of this field is to measure and map parameters that accurately describe the nature and shape of the seabed in relation to the geographical position of land features and other marine movements, ensuring maritime navigation safety.
Master's Degree Admission:
For admission to this program, a bachelor's degree in related fields such as Geomatics Engineering, Geodesy, or other similar disciplines is typically required.
