3. Project in Seoul
4. Cases of Application
5. Future Plans
1. Background
• Buildings are becoming bigger and more complex• An increase in indoor activities(80% of daily life)• A growth in thought of disaster prevention in indoor space• Needs for civic services for people’s safety and convenience through the integration of indoor spatial
information
1. Background
3D Indoor spatial information in Seoul
An increase in the complexity of building
structure
People spend 80-90% of their time indoors (NOKIA Source Strategy Analytics)

Geometry data+Properties data
3D Geographic Information System
Many disaster occurred in indoor
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

2.2 Trends (Korea)
1. 3D laser scanning based Indoor map construction
3D indoor spatial information construction project in Seoul
2. Construction of indoor map using camera(Panorama)
3. BIM model data construction for practical use 4. Construction drawing(2D CAD) based Indoor map construction
