For years, some of India’s most valuable geospatial datasets remained scattered across government departments, research institutes, or private organizations. They held immense potential to transform logistics, strengthen climate resilience, and support smarter urban planning, but they remained difficult to access, buried in different formats and lacking interoperability. Recognizing this challenge, the Government of India through the Department of Science and …

Introduction Traditionally, data exchanges have relied on a centralized architecture — where both the control plane (responsible for cataloging, authorization, and access management) and data plane (where the datasets are stored and served) are hosted centrally. While functional, this model faces challenges of scalability, data governance, and security risks, especially as data volumes and contributors grow. The GDI federated architecture …

Introduction Runoff is a vital component in hydrological modeling, particularly in regions with seasonal rainfall such as India. The Soil Conservation Service Curve Number (SCS-CN) model is commonly used to estimate runoff by considering land use, soil type, rainfall, and Antecedent Moisture Conditions (AMC). This study applies the SCS-CN model to assess runoff in Varanasi, focusing on the Southwest Monsoon …

Introduction Groundwater forms the backbone of water security for millions across India, serving as a primary source for drinking, irrigation, and industrial use. Yet, as demand increases, groundwater contamination and over-extraction are growing concerns. This calls for the need for systematic and scalable groundwater quality assessment across diverse geographies. This study presents a modern, geospatially enabled approach to understanding groundwater …
