Spatial address databases
BUILDING THE GIS
Statistical address points
• address points for dwelling locations (only)
Statistical division borders
• Statistical regions
• Census areas

BUILDING THE GIS
• Ortophotomap,
• Cadastral Data,
• Administrative division borders,
Primary:
• LPIS (Land Parcel Identification System),

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
