India's Coastline: How Improved Measurement Reveals a Longer Shore

Imagine India's coast is like a line you're measuring.

An old map, using a big ruler, missed all the small bays and curves.

Now, using super-detailed maps and new tools, we see the coast is much longer!

This isn't because India got bigger, but because we're measuring more accurately.

The old measurement, from the 1970s, used less precise methods.

The new one, using high-tech tools, captures every nook and cranny, making the coast seem longer.

It's like when you measure a squiggly line – a smaller ruler gives a longer length.

This longer coast matters for things like security and planning for natural disasters.
