GURASBob BoschmanLocal Government Spatial SeminarMarch 15-16, 2010

Purpose of GURAS Presentation• Introduce the audience to GURAS.• Re introduce some of the audience toGURAS.• Hopefully establish a mutually beneficialway forward to improve addressing inNSW..

What is GURAS?GURAS is:Geo codedUrban &RuralAddressSystem

What is GURAS?• It is a non discriminatory property basedaddress system that contains unambiguousaddresses• It treats Urban and Rural Addresses in thesame manner i.e. the construct of eachaddress is to have a (minimum) housenumber, road name and road type andsuburb• Uniquely locates addresses (geo code), witha real world position (latitude and longitude),for each address point

Why GURAS?It was identified that NSW did not have a statewide address data set that was•Reliable•Authoritative•Routinely maintained•Globally accessible……. and•Spatially enabled.

The Drivers• A requirement (commitment) of NSW tocontribute to the geo coded national addressfile (G_NAF)• A vehicle for supporting and housing ruraladdressing• To provide assistance for the delivery ofemergency services

Why LPMA?To satisfy the earlier stated criteria LPMA hasownership of data pertaining to:• Titling (Land Titles Office)• Property (Valuations – Valuer Generals)• Mapping (Spatial_ DCDB, DTDB andImagery)

Current sources of address data• G_NAF• Geocoded National Address File produced by thePSMA. The benchmark GURAS address data set.• Valnet2• Address field held against properties within VG‟sdata base• Councils• Provided by councils from either property or ratesdata bases• Australia Post• Used for validation purposes and ingestion of„secondary‟ addresses

Underlying LPI Spatial DataDCDB_ Defines the legal parcel fabric of NSW andcontains road name data as per gazettals if availableDTDB_ Physical representation of the road networkalso containing road name content aligned withDCDB where applicableValnet (Property)_ Defines the shape of the property inrelation to its lots and built against the same lots inthe DCDB

Address verification (spatial relationships)The key relationships in address verification are sodesigned to ensure correctness, uniqueness and truespatial location:That the address is associated with and containedwithin the unique „property‟ as defined in Valnet2Road Name in the address string is that of the DTDBroad entity it is associated with.That the suburb name of the address is that of thedesignated suburb name and polygon as it is in theDCDB and established under the GNB Act;1966.

Authoritative AddressGURAS considers an address to be„Authoritative‟ when it is defined by,formalised within and adheres to currentlegislation.Presently there are a number of legislationsthat contribute to the final construct of anaddress and is considered to be hybrid in itscharacteristicsHaving said that the authoritative addressgoes beyond being subjective or merely anopinion it is the best that can be applied.Insert your footer hereeven long ones

Legislative influences on addressing andGURASLocal Government Act 1993, No 33Section 124, Chapter 7, Part 2, Division 1,Clause 8(Property Numbers)Roads Act 1993 No. 33Part 10, Division 4, Clause 162 & 163 (Authority fornaming roads)The Roads (General) Regulation 2000Part 2, Division 2, Clauses 7-10 (Procedures for namingroads)Geographical Names ACT 1966 No 13Clause 2 – (Naming of Suburbs/Localities)Valuation of Land Act 1916 No 2(Separate and combined valuations)Conveyancing (General) Regulation 1998 - Sect 16Supply of Street Addresses . .

GURAS a single point of truthWithin LPMA it is the intention that GURAS isthe single source of truth for propertyaddresses*.• It needs to be remembered that GURAS isestablishing the attributes for and the location of thephysical address of a property as distinct from thepostal address.• The postal address is relevant to individuals that areassociated with the property.

Ensuring ConsistencyWhilst GURAS processes and spatialvalidation provides the means to testaccuracy and the correctness ofaddresses the aspect of consistencyrests with the creators of an address.

Ensuring ConsistencyConsistency can best be achieved byadopting the requirements of andadhering to:• “Australian Standard AS4819 – GeographicInformation-Rural and Urban Addressing”• The obligations as set out in “The Local GovernmentAct”• Fulfilling the requirements of “The Roads Act:1993”and the Geographical Names Act;1966”

Ensuring ConsistencyTo ensure long term consistency (andconfidence) in address data it is imperativethat Standards and Legislations are linked.StandardsLegislation

Ensuring ConsistencyHaving standards and legislation connectedis pivotal in establishing best practices.To ensure that these documents retainrelevance, working groups like “NAWG”,Spatial Interest Groups (SIG) and anyworking groups that may emanate from thisseminar will continue to play a critical role tosupport consistent applications and outcomesfor address data.Insert your footer hereeven long ones

GURAS ProgramsGURAS has defined its long termactivities into 2 distinct categories:Upgrade and Update.Upgrade: Is the action of improving existingGURAS addresses by implementing a seriesof rigorous QA reports over the content.Update: Is the action of ingesting new andchanged content from recognised sources egCouncils, Australia post and currently Valnet2

GURAS ProgramsWhere do we start ?At this stage the options are plentiful…….We can?Follow the Valuer General‟s g-val program.Start on a regional basis..Rural or Metropolitan.Start on a co-operative basis…willing LGAsStart on a emergency services driven basisStart on a request basis….LGAs requestingGURAS QA over their address contentStart on a program based on latest imagery

GURAS Programs……happy to takeadvice.So….In what directiondoes GURAS go?

GURAS Challenges• Engaging 152 Councils to participate inaddress activities.• Gathering details of „Complex Address‟ sitessuch as permanent caravan parks, shoppingcentres, industrial sites, housing commissionsites, large educational facilities andretirement villages.• Establishing „Addressable Routes‟ for ruraladdressing.Insert your footer hereeven long ones

GURAS Challenges – Complex AddressesOne issue of significance is finding the„missing address‟.Where is to be found?What details are associated with it?How does GURAS show it??

Complex Address Sites• Some examples

Complex Addresses Sites

Update ProgramAddress Updates (new) are currentlyprocessed via an automated servicereceiving bulk address feeds fromValnet2.Some additional incremental updatesare being provided by some councils viaemail and are being manually insertedinto GURAS and Valnet2 by GURASstaff.Insert your footer hereeven long ones

Update ProgramApart from new address details („a_spatial‟)GURAS is dependant on „spatial‟ updatefeeds from theDCDB…new and changed lot fabric.Valnet2…new and changed property andaddress details.Eventually….. Road segment feeds from theDTDB

Update ProgramIt must be pointed out that whilstGURAS is dependent on spatial contentfrom the DCDB and DTDB it is adiscreet data base in its own right.

Local Government providing „Updates‟From Where?To Where?Single source of truth in CouncilsHow? Xml, Excel, csv files, geometriesWhen? On request? Systematically

Council as an address source• It was mentioned earlier that GURAS is tobecome the single source of truth foraddresses within LPMA.• Where in fact is the single source of truth foran address within each council?• LPMA needs to understand the workings ofeach council with regard to this to ensurecommunications and information sharingremains appropriate, relevant andunderstood.Insert your footer hereeven long ones

Understanding Council‟s environment.• To assist GURAS staff in gleaning anunderstanding of the environment ofeach council the following questionsmay be asked.Insert your footer hereeven long ones

Council Address Work Flow QuestionsQuestion No Question Response1 How and why is an address created?2 What justifies an address change?3 Where in Council's environment is the action undertaken?What is the domino effect of this action through council's4 departmentsWhere is the detail recorded (Council's primary / authoritative)5 address data set6 Where else is it recorded and how is it delivered?What other actions and notifications result from / for an7 address?Road name approvals and gazettalsRoad name Private or publicSuburb name impact..Is a change known or requiredGNB'S positional extent policy.
