When do we use THAT?

[Paulys]

Hey, who reading this topic. Who can explain me when do we use "THAT" in English?
I watched a film and I saw a lot of example.
For example:
Kid: Excuse me, but this is an emergency.
Woman: Yes sir.
Kid: What city is that over there?
Woman: That's New York, sir.
So, why did woman say "That's New York" ?
If I had I would have been instead that woman I was be say "It's New York"
Next for example.
Man: Smell that? (If I had I would have been instead that man I was be say "Smell it"
Man2: Yeah.
So, why they used that?

It was very hard for me to explain you one of the biggest my problem is that I sometimes don't feel any difference between it & that.
I think that I did any mistake. Please correct them.

God will kill me, because I did a lot of the mistakes. Forget me, I am dead! -=REST IN PEACE=-

I sure hope He won't. It would be a shame because I enjoy reading your posts and you can't write any posts when you're dead.

Remember that we say "make a mistake", not "do a mistake".

That's New York, It's new York or simply New York are all correct in this context.

Smell that? asks whether you can smell an unspecified aroma.

Smell it? refers to a specified scent. 'I'm wearing a new perfume; smell it?'
