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

The only set of address points in Poland that:

• is complete,

• has been verified in the field,

Created and maintained within official statistics

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
