Biruni made a number of contributions to the Earth Sciences. In particular, he is regarded as the "father of geodesy" for his important contributions to the field of geodesy, along with his significant contributions to geography.

At the age of 17, Biruni calculated the latitude of Kath, Khwarizm, using the maximum altitude of the Sun. He discovered 7 ways of finding the direction of the north and south, and discovered mathematical techniques to determine exactly the beginning of the season. He elaborated a method to calculate the Earth's diameter - Using the astrolabe and the presence of a mountain near a sea or flat plain, he calculated the Earth's circumference by solving a highly complex geodesic equation, arriving at a figure close to modern values of the Earth's circumference. His estimate of 6,339.9 km for the Earth radius was only 16.8 km less than the modern value of 6,356.7 km.. This method is known in the modern world as the "al-Biruni Law",

His Masudic Canon contains a table giving the coordinates of six hundred places, almost all of which he had direct knowledge.
