Production model of ‘Census’ statistics
Downsizing of processes in IBM mainframe
 modernising production of statistics
 integrating digital map data, locations of
statistical entities and attribute data
together in the same environment
 statistics are produced in the old and new environment
and results are compared

Spatial database is a data base containing
digital map data and location data,
Also called: geodatabase or GIS database
Spatial database is a logical concept,
physically data is in more than one
SQL Server-database.
Geometry is administrated by ArcSDE-product

Spatial data production and use
Micro- and macro-data
Map data,
locations of statistical data
as spatial data types

GMF : General Feature Model (Application Schema ISO 19109)
GML : Geographic Markup Language (ISO 19136, OGC)
 GMF:n XML-implementation

Benefits of using spatial database
Commonly used database
 Statistical attribute data in the same environment
 Maintenance in one place
 Processed will be simplified
 Quality will be better
 More possibilities
 Administration of large data is better

Central spatial database is a
part of spatial infrastructure and is
one of the most important clue
