The full form of **这是哪？** is **这是哪里？** or **这是哪儿？**, means **Where is this?**, while **这是在哪？** represents **你这是在哪里？** or **你是在哪里？**, means **Where are you now?**, and **我们这是在哪里？**, means **Where are we now?**, the subject is omitted. Also, you can consider they have the same meanings.

The key to differentiate between 这是哪（儿） and 这是在哪（儿） is to understand the different usages of the character '这'.

这 have several meanings, I just listed two of them relevant to this topic:

1. referring to a person, thing, or place, like the word 'this' in English. For example, 这是我家。 means **This** is my home.
2. used to emphasize 现在, like the word 'now' in English. For example, 我这就来. means I am coming **now**.

这是哪？, 这（subject）+ 是（verb）+ 哪（target）, simply means "where is it?".

这是在哪？, 这（intensifier like an adverb in English, modifying 是）+ 是（verb）+ 哪（target）, implies **现在**是在哪, apparently the sentence omits a subject "我们". The complete sentence should be "我们这是在哪", and the equivalent sentence in English is "where are we now?"

In this case, I gather your friend asked this question in your moments of WeChat, where you might post some scenery photos. So, 这是哪("where is it") is more accurate here.

Some explanations on these sentences you quoted above:

这是（在）哪里？: This is the same as "这是（在）哪"，as talked above.

这是（在）哪儿？: This is the same as "这是（在）哪"，as talked above.

这里是（在）哪里？: 这里是哪里 == 这是哪里==这是哪（儿）， 这里是在哪里 is unnatural and it should be either 这里是哪里 or 这是在哪里. The difference has already been talked about.

这里是（在）哪儿？: 这里是哪儿==这是哪儿==这是哪里， 这里是在哪儿==这里是在哪里， which is unnatural and should be either 这里是哪儿 or 这是在哪儿. The difference has already been talked about.

PS: In this case, 这是在哪 could be short for 这是在哪里拍摄的 or 这是在哪里照的.

* "这是哪？" short for "这是哪里？"; It means "where is this place/ what place it is?" (you want to know the name of a place)

Example:

> A and B are at a park,

> A asks B: "这是**哪(里)**?" - "**where** is this **place**?"

> B answers: "这是佛光山公园" - "This is Buddha Light Mountain Park"

* "这是在哪？" short for "这是在哪里？" It means "where it is at?" (you want to know where an object is located or where an event took place)
