Google has extended its Indoor Google Maps to 31 popular destinations in Singapore.

Iconic buildings like the National Library, Marina Bay Sands Hotel, Asian Civilisations Museum, National Museum of Singapore and ArtScience Museum, now have their floor plans uploaded to Google Maps.

Gone are the days when you have to look for a map directory to find your way inside a multi-storey building. Both android and iOS users can now navigate through museums, convention centres, library and shopping malls with Google Maps.

The maps are automatically turned on when you zoom in on a location. Users can also switch between floor plans for different levels within the building. Google launched its Indoor Google Maps to Singapore earlier this year with maps to 22 shopping malls. Singapore is the second country in Asia to feature Indoor Google Maps, with Japan's Tokyo and Osaka being the first two cities to offer it.
