Map Projections: Meaning and Examples

📚 Quick Study Guide

🌍 Map projections transform the Earth's 3D surface onto a 2D plane. 📐 All projections introduce distortions in shape, area, distance, or direction. 🗺️ Common types include cylindrical, conic, and azimuthal projections. 🧭 Mercator is a cylindrical projection preserving angles, ideal for navigation but distorts area. 📍 Equal Area projections preserve area but distort shape. An example is the Gall-Peters projection. 📏 Conic projections are good for mapping mid-latitude regions. 💡 Choosing the right projection depends on the map's purpose.
