2. Cases and Trends

Google Indoor MapMicrosoft Bing Venue Maps

• Global companies such as Google, Apple and Microsoft have been constructing indoor spatial information• Indoor map service : 2D Indoor Map, pictures (360°panorama) based indoor map provision• Expanding the construction for indoor map from the U.S to worldwide, predicted about 120,000 places in 2016 (2012, IMS Research)

2.1 Trends (World-wide)

Google Indoor Maps Google Maps Floor Plans

TrimbleNOKIA< Indoor map installation in companies>

• Constructed indoor map services at 78 major underground shopping arcades• Indoor map service : 2D Indoor Map, pictures (360°panorama) based indoor map provision• Launched 3D indoor location based service at Incheon international airport• Expanding to construct 3D indoor map for most public buildings in Seoul until 2016
