Earth science data activities in India
Earth science tries to reconstruct events of the past from the imperfect and limited records contained in rocks. It also helps us to predict such hazards as earthquakes, landslides, high floods, volcanic eruption, etc., for which better knowledge of geological phenomena is required. Earth science also has very importan t economic aspects. We depend on it for all our mineral resources including ground water and energy. Minerals playa vital role in industrialization and national economy. The recent developments in the generation, collection and analysis of earth science data calls for the acquisition of greater volumes of information than were required and readily recordable previously. In order to assimilate these necessary data, computers have been employed for storage, retrieval and analysis as an essential preliminary step to data interpretation.
