Geodesists also measure distances between multiple points, which include those between Earth and other planetary bodies. The pull of gravity can be measured with amazing accuracy (detecting changes of one billionth of your body weight). Geodesists study things that can change the topographical aspects of the earth, such as gravitational pull, tectonic plates, polar activity, and the rotation of the Earth. They are able to measure the distance of two points on Earth to within approximately 1mm, and are able to track the rise of the mean ocean surface to about 1.7 mm per year. By using this method, they have the ability to create detailed mappings of the Earth's shape, measurements, and characteristics. Geodesists use equipment such as remote sensing, and since the invention of satellite technology they have used a GIS (geographic information system) to calculate distances. They take measurements and use powerful telescopes to calculate planetary processes. Geodesists survey land to determine precise coordinates of topological features of the earth. This field differs from fields like cartography or geography, as it is primarily concerned with how things that are not visible to the human eye alter the Earth’s appearance. Geodesy is the science of measuring and understanding three properties of the Earth:
Just as a growing child gets measured, the Earth too needs to keep track of its changes - for example, measuring melting glaciers and moving plates. The Earth is growing and changing all the time.
What is the workplace of a Geodesist like?.
