¿Podría usted decirme si la taquilla está más cerca de lo que indica el mapa?

Podría is the conditional form of poder, and here it makes the request more polite and less direct.

• ¿Puede usted decirme...? = Can you tell me...?
• ¿Podría usted decirme...? = Could you tell me...?

In Spain, this is a very normal way to sound courteous, especially with strangers, staff, or in formal situations.

You can leave it out.

Spanish often drops subject pronouns because the verb already shows who the subject is. So all of these are possible:

• ¿Podría usted decirme si...?
• ¿Podría decirme si...?
• ¿Me podría decir si...?

Including usted makes the sentence sound a bit more formal or slightly more emphatic, but it is not required.

Because me is an object pronoun attached to the infinitive decir.

So:

• decir = to tell
• me = to me
• decirme = to tell me

This is very common in Spanish with infinitives. You could also place the pronoun before the conjugated verb:

• ¿Podría decirme si...?
• ¿Me podría decir si...?

Both are correct.

Here si means whether or if and introduces an indirect yes/no question.

So the structure is basically:

• decirme si... = tell me whether / if...

Important: this is si without an accent.

• si = if / whether
• sí = yes

That distinction is very important in writing.

Because estar is used for location.

The sentence is talking about where the ticket office is located, so Spanish uses estar:

• La taquilla está cerca = The ticket office is nearby

Using ser here would sound wrong because ser is generally for identity, classification, origin, and similar ideas, not physical location.

In Spain, taquilla often means a ticket office, box office, or ticket window, depending on the context.

For example, it could be the place where you buy tickets at:

• a station
• a cinema
• a theatre
• a museum

Be aware that taquilla can also mean a locker in other contexts, so the exact meaning depends on the situation. In this sentence, it clearly means the ticket office/window.

This is a comparative structure meaning closer than the map indicates.

The key pattern is:

• más + adjective/adverb + de lo que + verb

Examples:

• más caro de lo que pensaba = more expensive than I thought
• más lejos de lo que parece = farther than it seems

In your sentence:

• más cerca = closer
• de lo que indica el mapa = than what the map indicates

So the whole idea is: closer than the map shows/suggests.

Because Spanish often uses de lo que after a comparative when what follows is a whole clause rather than just a noun.

Here, the comparison is not simply with a thing, but with what the map indicates. That is why de lo que is used.

Also, cerca normally goes with de, as in:

• cerca de la estación
• cerca de aquí

That de remains part of the structure here, which is another reason the sentence naturally comes out as más cerca de lo que...

Yes. Indica is correct and fairly neutral, but other verbs could work depending on nuance.

For example:

• muestra = shows
• señala = points out / indicates
• pone = says / shows on it (more informal, very common in Spain)

So you might also hear:

• ...de lo que muestra el mapa
• ...de lo que pone en el mapa

But indica is perfectly good Spanish and sounds a bit more formal or careful.

Yes. Spanish word order is flexible here. These are all natural:

• ¿Podría usted decirme si la taquilla está más cerca de lo que indica el mapa?
• ¿Podría decirme usted si la taquilla está más cerca de lo que indica el mapa?
• ¿Me podría decir si la taquilla está más cerca de lo que indica el mapa?

The differences are mostly about rhythm, emphasis, and style, not basic meaning.

Because standard Spanish punctuation marks the start and end of a question:

• ¿ at the beginning
• ? at the end

This helps the reader know from the start that the sentence is a question. In formal written Spanish, both are required.
