![]() Here we discuss Datum’s definition and how Does Datum work in Geographic Information System along with the advantages.One must pay extra careful attention to the datum they are referencing. The live and perfect example of a Datum working in the Geographic Information system would be Google Earth. There are abstract vertical and horizontal lines on the globe that divide and distribute the region based on the coordinate system. Earth doesn’t have its true shape in a simple sense, so datum helps us know about the spheroid, sphere or elliptical form of earth. There are various calculations and hypotheses derived from the observations and the experiments that are performed. This part of the topic is crucial and yet complex simultaneously hence engineering experts with GIS and mathematics knowledge work on this. It also helps in communicating the part of functional movements and relationships. ![]() Datum helps in making the recurring dimensional measurements.Geodesists majorly use it to calculate water body movements like tidal movements, Sea level change, and even river width changes.The Global Positioning System uses datum to understand the shifting in the coordinates. ![]()
