What is SGI(Statistical Geographic Information)? - Survey Results(Text) + Position Information - Enabling topological analysis on spatial or positional relations
What is SGIS(SGI Services)? - Inquiring, Analyzing and Decision Making Services using SGI
The Objectives of SGIS - Statistical Survey Supports - Improving friendliness of Statistical Information through visualization

Providing Statistics- Population: sex/age, educational attainment, religion, marital status
- Household: number of rooms/living rooms/kitchens, heating facilities, type of occupancy, generation
- Housing: year of construction, total floor space, housing type
- Establishments: number of establishments(industrial classification, establishment year), number of workers(by industry, 2004 ~2008, 2000~2003 is now under implementing

Census Individual Spatial DB
: Position Information (Points) of Residence/Establishments +
Census Map + Boundaries(administrative, EDs)
* Census Map : Base map for Census, administrative region (about 3,500)
and ED maps(about 0.3 million)
Statistics Navigator : Geographic Information with Census on Population/Housing, Establishments
Interesting SGIS : 7 kinds of thematic SGIS based on Statistics Navigator
