Imagine, you have got postcards of various places (countries, cities, towns etc) and you are now showing your friend those postcards, which have such pictures taken from above. So, when you are showing these to your friend if you want him to guess, how do you ask:
1- Where is that?
2- What place is that?
3- Where was that picture taken?
4- What is that place?"
5- Where is this place?
I did some research with some similar content and I have found the first three suggestion, but none of them seems to work in this case. Here are what I have found:
1- "Where is that?". (This sounds like OK for particular things such as landmarks in an area, but not for huge pieces of land like cities in pictures taken from above. For example if you show a postcard of Tokyo taken from the air, can you say "Where is that" referring to the whole area in the picture? I am not sure, because "that"* sounds like it points to a thing like a landmark in a city but not the whole city area which the landmark is in.)
2-"What place is that?" (The answer would be "That is supermarket, or a stadium". So, this structure won't work either.)
3- "What is that place?" (Same as above, "That place is a huge park." It does not refer to the whole area shown in the picture.)
4- "Where was that picture taken?" (Not referring to the area particularly. The answer would be "It was taken on a hill or under the sea etc) (Again this is not what I want to ask.)
So, the only way I could think of is "Where is this place?" If you show a picture of any place which was taken from the above with all the buildings, I think this seems to be the only way to ask someone to guess what the whole place shown from the above is called?
So, my question is: Is "Where is this place?" idiomatic for asking a question, which would refer to "the whole area shown in a picture taken above"?
For instance:
A: Where is this place?
B: It is China.
