Work schedule (nationwide)
BUILDING THE GIS
• reference material collection
January 2009 – December 2009
• reference material processing
January 2010 – May 2010 • address point
acquisition
January 2010 – June 2010

Results
BUILDING THE GIS
210 GIS operators in 63 regional offices
6 months time (January – June 2010)
5,7 milion statistical address points acquired
GIS built from scratch in a very short time

CENSUS UPDATE OF ADDRESS POINTS
Census for GIS
9
Update in municipalities
CENSUS UPDATE OF ADDRESS POINTS
January 2011 – 3 weeks
• municipality authorities obliged to verify address point location
• internet map service with on-line editing
• results imported automatically to spatial address databases
10
Visual survey by enumerators
CENSUS UPDATE OF ADDRESS POINTS
11
• mobile application
• every address point verified
• results imported to spatial address databases
Results
CENSUS UPDATE OF ADDRESS POINTS

Summary
immense effort to create spatial address databases paid off
census
useful in the census
improved in the census
point based statistics can be presented
in any division of space
administrative /statistical
units
grid cells of any size
Geostatistics Portal
access to huge amount of statistical
data
variety of cartographic presentation
methods and tools
