Addresses – Addressing ?

• We all know, what an address is, don’t we ? When we talk about addresses, do we mean the same ?

to address means, to reach somebody, to find a certain place

• Addressesare unambiguous maintained interpretable (locatable) common known andthey create spatial relations

Address-Solution for Austrian Administration Dipl.-Ing. Rupert Kugler, Austria Page 5

What is an Adress ? (1)

• Address

is a location with spatial relation –

it has always to be in relation to a cadastral parcel but not always in relation to a building

(an address could exist without any building)

Address-Solution for Austrian Administration Dipl.-Ing. Rupert Kugler, Austria Page 6

What is an Address ? (2)

• Buildings’ Addressesare additional features for an exact identification of a building, situated on an address

but not each building has to have an address

(for example: agricultural buildings, stables)

• Apartments’ Addresses

are the additional features for an exact identification inside a building (important for the central residence register)

The Address Model

five layers

• municipalities• streets, roads• addresses• addresses of buildings• apartments (not strictly regulated in Austria)

Register of Addresses (1)... is the Austrian central address database, in which - each address

- with an unambiguous key (address code) and - standard attributes - is stored with a clear standardized model of

data maintenanceAuthenticity - each address is correctly updated by the only

competent and responsible institution, the municipalityAvailability - each address is available, updated and

centrally serviced via Web-Services or Application Service Providing

Register of Addresses (2)

is the authentic database for economy and administrationwith spatial reference - each address is available, not

only maintained and centrally serviced, but even geocoded and spatial referenced withGeo Basic Data of BEV

the DKM (Digital Cadastral Map) the DOP (Digital Orthophoto)the ÖK 50 (Austrian Topographic Map 1:50.000)

for commercial use – clear licence policy in the Standard Price List for BEV-Geodata

Register of Addresses - History• In Austria

a Basic Census was taken every 10 years (the last one in 2001) maintaining the addresses,

in order of a governmental requirement the next census will have to be based on central databases.

• In the year 2004 a new and common Register of Addresses was established.

• Preliminary work (municipality – STAT – BEV since 1998):comparison of street names (109.000 names)comparison of addresses (3,6 Mill records )each address was matched to one or more parcels

• All buildings were referenced to one or more addresses.

Advantages of a Register of Addresses (1)

• for a Citizen - for the Public

the single address is public

free request for everyone via Web for a single “correct” address with attributes and georeference - using eGA

• for the Municipality

each address has to be updated only once by the municipality in all federal databases (basic data 2001)

basic georeferencing has been carried out using the Digital Cadastral Map (DKM)

Advantages of a Register of Addresses (2)• for the federal provinces and the republic

the register of addresses is the base of all data connected with addresses of the federal administrationAustrian-wide homogeneous georeference for:– disaster- and risk-management– administration– reduction of costs through –

avoidance of redundant maintenancestorage of the keys of addresses instead of the whole addresses together with the company data….

Advantages of a Register of Addresses (3)

All these advantages are the base for addressing in e-Government.

A second kind of addressing is “electronic addressing”

described and regulated in the

e-Government Act

Austrian-wide „Keys“ (1)

• Addresscode each official address, appointed by the community, gets an Austrian-wide unambiguous code

• Subcodeeach building, situated on an „Addresscode“ , gets a subcode

• AddressnumberAddresscode + Subcode Addressnumber

• Object Numberadditional - each object has one unique objectcode

Address-Solution for Austrian Administration Dipl.-Ing. Rupert Kugler, Austria Page 16

Austrian-wide „Keys“ (2)

this means – an object has• one unique object number• at least one adressnumber

– but if the parcel has more addresses, the object on the parcel has more adressnumbers

– one of them is the “Main Adress”– the relation is always the object number

Conclusion• Register of Addresses

contains all authentic und maintained addresses of Austria on the Address- und Building Layer

- with georeference

- with attributes- in unambiguous kind und access

- all buildings are recorded with addresses and georeference

- the data model contains even difficult “specialities”- and is expandable
