How to Get Real-Time 3D World Map Data (Focused on India) in Unity for Tabletop "Iron Man"-Style View?

Hi everyone,

I’m working on a Unity project where I want to create a 3D, tabletop-style map view similar to what’s shown in “Iron Man” movies — specifically focused on real-time mapping of India. I’m aiming for an interactive, high-detail, city-level 3D map that can update with live data if possible, showing buildings, landscapes, and other map features in a dynamic way.

My Questions:

  1. 3D Map Data Source**: Are there any plugins, APIs, or datasets that provide detailed 3D map data specifically for India that integrate well with Unity?
  2. Real-Time Updates**: For real-time data like traffic or weather overlays, are there Unity-compatible sources or APIs that offer this information?
  3. Performance Tips**: If anyone has experience with similar projects, do you have any recommendations for managing performance when rendering a detailed, interactive 3D map?

I’m aware of some mapping solutions like Mapbox and Mappls, but I’m not sure if they support the level of detail and customization I’m looking for. Any suggestions, resources, or guidance would be greatly appreciated!

Thanks in advance!
