Need suggestions for indoor maps - Interactive Maps Application

Hi everyone,
Hope all of you are all right.

I am working on the implementation of Indoor Maps. For that, there are several options for adaptation. So I need your suggestions.

The first question is how would the users be using the indoor maps?

  • Would they be using images for each level?
  • Would they prefer to have a normal map and add shape-like objects to it?
  • Or would they like a mixture of both i.e. a normal map with images as levels?

For a normal map with multilevel structures -
For using only images -

What would you prefer to have if you ever had to use the application for creating indoor maps?
