GIS, or Geographic Information System, is a powerful tool for capturing, managing, analyzing, and visualizing spatial data. It combines geography with technology to help us understand patterns, relationships, and processes in our world.

📌 Key Concepts of GIS

  • Spatial Data: Data that includes geographic coordinates (e.g., latitude, longitude)
  • Layers: GIS data is organized into thematic layers (e.g., roads, rivers, population density)
  • Analysis Tools: Includes buffering, overlaying, and spatial statistics
  • Visualization: Maps, 3D models, and interactive dashboards

🧭 Applications of GIS

  • Urban planning 🏗️
  • Environmental monitoring 🌱
  • Disaster management ⚠️
  • Business logistics 📦

🧠 How GIS Works

  1. Data Collection: Gather spatial and attribute data
  2. Data Storage: Use databases or file formats (e.g., GeoJSON)
  3. Data Analysis: Apply spatial algorithms to derive insights
  4. Data Output: Generate maps or reports for decision-making
