• Each variable of the BR is linked to different information sources, ranked by degree of importance

• For each variable a cross-check is made by comparing the information provided by the source with the one contained in the BR

• Concerning the economic variables a growth rate is calculated and an acceptable range is established. Those that fall out of this range are subject to further analysis

• In 2011, Statistics Portugal constructed a national geographical database of all the georeferenced buildings from the 2011 Census

• This geographical dataset has been used to reference census data at point level and to support the creation of a National Dwellings Register (FNA)

• FNA is updated by data available in different sources: (1) surveys conducted by Statistics Portugal: (2) administrative sources

• Statistics Portugal strategy to improve the efficiency statistical process

• Grant: “Merging statistics and geospatial information in member states”

GOAL• Implement a spatially enabled and quality-controlled point

based infrastructure for the production and delivery of BR statistics at all relevant geographic breakdown levels by means of data integration

Action

The current action is integrated into:

» 16

The address is the key element to directly or indirectly match the records with the existing BGE

following a step-by-step approach based on locators capable of sequentially pinpoint the BR records

A different mix of those locators has been used for the cases processed

BR Geo processing

MORADA_CP7  Complete address composed by type of road, name, number, 7 digit postal code 

BSA_CP7_DTA BSA_CP7_ESQ  Used over the BSA in order to overcome discrepancies in the address  

MORADA_LOC_CP4 Uses the locality name and the 4 digit postal code 

CP7  Based on the 7 digit postal code, which is a linear structure used to code each block façade composed by the CP4 and 3 additional digits 

CP4  Based on the 4 digit postal code, which is a polygonal structure used to code each postal distribution area
