1. SGIS(Statistical GIS)_An Overview
 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

1. SGIS(Statistical GIS)_The Services
Types of Services
 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
 OpenAPI

 Kinds of Interesting SGIS
- Experiencing the Statistical Map
- Looking for a new neighborhood
(e.g. statistics on residential and transportation environments)
- Monthly SGIS
: Major Monthly Statistics such as CPI
- e-MiJi(provincial changes in the future)
- Moving Population Pyramid
- Surname Distribution

Moving Population Pyramid
 Shows the changes in population structure based on the population
estimation by age in the whole country and by 5-year age in
Si/Do(Metropolitan cities/Provinces)

Surname Distribution
 Provides the distribution of the surnames in different regions
based on the population census data in 1985 and 2000.

1. SGIS(Statistical GIS)_OpenAPI
Introduction to OpenAPI
 Supports to utilize the Statistical Geospatial Information
from users’ systems
 Ways of API Provision
- Map API with java script/DHTML format
- Document for API Specification is given
 Procedure of Admittance
- Online issue of Authentication Key
14/22
2. SGIS(Statistical GIS)_OpenAPI
 Apply to issue the authentication key after logon to SGIS
(http://sgis.kostat.go.kr)
 After checking by system administrator, accept/deny the issue of
authentication key
 Checking of issue of authentication key at [MyPage]-[Messages]page

The Directions
- Adaptation of New Address System
• Conversions to New Address System
•
• Finding out an advanced method for implementing Census DB
• Adapting Global Geodetic System for compatibility
- Improvement of SGIS Services
• Joining Geospatial & Statistical Information using Registers
•
• Enrich the Service Contents Continuously
Costs and Efforts Reduction & Service Improvement

2. SGIS in the Future
 Adaptation of New Address System
based on the numbers
on specific districts
2012~
based on the streets &
numbers on buildings
 Changes in SGIS
- Base maps for Census Individual DB
- Finding advanced method for implementing Census DB
