Breaking Data Silos: How GDI is Transforming Access to Geospatial Information in India

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 …

GDI federated node: Smarter way of sharing your data without giving it away!

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 …

From Space to Soil: Leveraging Satellite and Weather Data for Flood Damage Assessment and Insurance Claims for Farmers

In an era where climate change is bringing more erratic weather patterns, the consequences of heavy rainfall and flooding on agriculture can be devastating. Farmers, particularly those reliant on seasonal crops, are often left in precarious situations, struggling to recover from lost yields. In the early September of 2024, in NTR district of Andhra Pradesh, this harsh reality recently came …

Assessment of Urban Heat Island (UHI) in Bengaluru Using Earth Observation Datasets.

Rapid urbanisation causes several issues, including the Urban Heat Island (UHI) effect, where urban areas experience significantly higher temperatures than their rural surroundings. This is due to several factors associated with urbanisation, including the replacement of vegetation with buildings, roads, and other impermeable surfaces that absorb and retain heat. Additionally, heat emissions from industries and vehicles also contribute to the …

Modelling Agricultural Land Suitability based on Soil Properties

Suitability studies in Geographic Information Systems (GIS) play a vital role in spatial planning and resource management by assessing the appropriateness of a given area for specific land uses based on various criteria. These studies integrate multiple datasets and analytical techniques to evaluate how well certain locations meet predefined requirements, thus guiding decision-making in sectors such as agriculture, urban development, …

Mapping Natural Drains From Contour Data

Natural drains act as channels that collect and transport surface water, influencing ecosystems. Mapping these natural drains is essential for understanding the flow of water across a landscape, which has wide-ranging applications in water resource management, flood risk assessment, and environmental protection. To generate natural drains, contour data available for Sirmaur, Himachal Pradesh in the GDI platform was used. Contours …

Flood Inundation Modelling

Flood inundation refers to the submergence of land areas due to rising water levels during extreme weather events, such as heavy rainfall or overflowing rivers. Accurate mapping of flood-prone areas is crucial for disaster preparedness, emergency response, and effective damage assessment. By predicting which regions are most likely to be inundated, authorities can develop early warning systems, plan evacuation routes, …
