Why the World Is Sliced Into 60 Zones — The UTM System Finally Explained Simply

In this video, we dive deep into the Universal Transverse Mercator (UTM) projection and the grid coordinate system—essential tools for modern surveying, mapping, and geospatial analysis. Avijit, a veteran Navy Surveyor with 37 years of experience, breaks down the concept using simple visuals, chalkboard sketches, and his signature orange peel demo. 🔍 What you’ll learn: ✅The difference between Mercator and Transverse Mercator projections ✅How UTM zones are created by slicing the globe into 60 segments ✅Why each zone spans 6° of longitude and how zone numbering works ✅How the Prime Meridian fits between zones 30 and 31 ✅Why UTM projection is limited to 80°S to 84°N—and how polar regions adapt ✅How grid coordinates are calculated using Easting and Northing ✅What the Central Meridian is and why it’s assigned 500,000 meters ✅How to handle surveys that cross zone boundaries ✅Why zone numbers are essential for accurate positioning ✅How grid North differs from True North—and how to visualize it 🎯Whether you're a student, surveyor, GIS analyst, or just curious about how Earth is mapped, this video offers a clear, practical guide to understanding UTM projection and grid systems.
