Topics of GIS @ NSI • Where from it has started? • Where are we now? • Main challenges and obstacles for producing gridded statistics
Where from GIS has started? • Wecantrace GIS history back over many centuries to when people first started using geographic information - 19th century Source: Öber,S , Springfeldt, P 1991
Where from GIS has started? • 1845 – Dr John Snow Choleraoutbreak • DR John Snowused a map to compare the geographical distribution of cholera victims and the location of water supply points. • Heconcluded that a major outbreak of cholera in Soho in 1845 was caused by contaminated water. • He was able to isolate a single water pump in Broad Street as the source of the cholera infection, thereby saving many lives. • Coulditbe a firstspatialhot-spotanalyse?

Where from GIS has started? StatisticsJapan produces grid statistics for population census since 1970 and enterprise census 1975 First PC based GIS in Canada 2000 Wide use of GIS in Census Statistcis Finalnd preparation for geocoding of the census results ca 1965 1986 1857 1970 2005 ca 1990 1967 WEB GIS 1845 „GE era“, OSM data The DIMEat the US Bureau of the Census in preparation for the automation of geocoding of the 1970 census 1932 Early navigation system

Where are we now? • Many of NSI in EU are disseminating statistics regularly mainly on aggregated statistical units level only • Producing gridded statistics : • NSI-s using registers updating gridded statistics yearly bases • NSI – s with traditional/combined methods censuses updating gridded statistics once per 10 years • Downscaling gridded statistics from LAU or other units (not disseminated for the public) • Using Web Mapping • NSI´s who only disseminate thematic mapping LAU or other units • Disseminating with using Google Earth (LAU or other units) • Gridded statistics with spatial queries • Quite few of NSI are conducting spatial analyses for creating new knowledge ( neighborhood clustering, delineation of statistical units, accessibility of recreational areas etc)
Some examples from outside of Europe • Statistics Japan thematic mapping application, grid data since 1970 Australian Bureau of Statistics Statistics South -Korea
Let´s look what others are telling about the GI http://www.youtube.com/watch?v=poMGRbfgp38&feature=list_related&playnext=1&list=SPB536E2CAE9CD2EE1
What are main obstacles ..??? • In producing gridded statistics, which are essential for society • In implementing GIS in NSI´s
