+# 🌊 GIFIS: Generalized Immersive Flood Information System Specification
+
+An open standard for immersive, interoperable flood information systems.
+
+---
+
+## 📖 About GIFIS
+
+The **Generalized Immersive Flood Information System (GIFIS) Specification** defines a structured and extensible data model for representing, validating, and publishing hydrologic and geospatial datasets in immersive environments (VR/AR/MR).
+
+It provides JSON Schema–based profiles for core entities such as **locations**, **events**, **alerts**, and **flood maps**.
+
+---
+
+## 🔑 Core Features
+
+- ✅ JSON Schema–driven validation for consistency and interoperability  
+- 🌍 Support for geospatial formats (GeoJSON, 3D Tiles, glTF)  
+- 🧾 Standardized metadata for hydrologic, meteorological, and sensor data  
+- 🚨 Integration with alerting systems and flood forecast models  
+- 🕶️ Designed for real-time immersive visualization (VR/AR/MR)
