However it hasn t entirely replaced surveying field instruments such as the theodolite electronic distance meter or the more modern total station due to the cost of the technology and the need for gps to be able to see the satellites therefore restricting its use near trees and tall buildings.
Satellite surveying is a form of land survey that uses location information provided by the gps satellite system to track the location of each reference point.
Surveying or land surveying is the technique profession art and science of determining the terrestrial or three dimensional positions of points and the distances and angles between them.
Such surveys are conducted for a location or region and referenced to the earth global co ordinate system with.

In surveying however greater accuracy is required and this is attainable because the observer and the instrument are stationary on the ground instead of in a ship or aircraft that is not only moving but also.
Consider upper side north.
There is a zero point of reference called a total station the instrument can be freely positioned so that all survey points are at a suitable sight from the instrument.
Modern ground based survey methods involve detailed survey which provides three space co ordinates for surveyed points to a high level of accuracy.
