Abstract
A precise datum is significant as a starting or reference point for a multitude of activities like floodplain maps, property boundaries, civil surveys, precise agriculture, crustal deformation and climate studies, and works requiring consistent coordinates. A large nation like India, with almost its own tectonic plate, must have a well-defined network of horizontal datum for determin- ing accurate and reliable 3D positioning for every user, anywhere and anytime. This article discusses the signifi- cance, methodology of realization and transformation, applications and static/dynamic coordinates for paving the way for a National Horizontal Datum in India.
