GSI

GSI is an acronym used by several organizations and brands around the world. In geology and earth sciences, it designates national or government-supported surveying bodies, while in manufacturing and hobby crafts it refers to a product company. The precise meaning of GSI depends on the context in which it appears.

Geological Survey of India (GSI) is a government scientific organization under the Ministry of Mines. It conducts geological mapping, mineral resource assessment, and geoscientific research. The agency maintains geoscientific data, supports mineral exploration, and contributes to natural hazard assessments and land-use planning across India.

Geological Survey of Israel (GSI) is a government research institution focusing on geology, groundwater, seismology, and natural resources in Israel. Its activities include hydrogeological investigations, earthquake risk assessment, and the provision of geoscientific data to support public policy, resource management, and safety planning.

GSI Creos Co., Ltd. is a Japanese company that develops and sells model-making materials and hobby supplies. Its product lines include paints, weathering agents, primers, and tools widely used by scale model builders and diorama enthusiasts. The brand is known for compatibility with popular model kits and hobby ecosystems.

Because GSI is used by multiple, unrelated entities, the term often requires contextual clarification. In scholarly or professional writing, it is common to specify the organization or field (for example, Geological Survey of India) to avoid ambiguity.
