Answer:
geodetic surveys
Explanation:
Geodetic Surveying is that branch of survey which deals with areas so extensive that it is necessary to take into consideration the true shape and dimensions of the earth. Its primary object is not to determine the exact Figure of the Earth, but to establish a very precise and rigid control for coordination of all other surveys.
