The 2015/16 audit against Local Government addressing revealed a 97.42% match rate. Key validation fields are 'SOURCE' and 'SOURCE_VERIFIED', respectively indicating the address source and date last validated against that source. Quality Assurance and validation routines are constantly being developed and applied in order to minimize any discrepancies or errors that may exist therein. However, both historical and ongoing with current AS/NZS 4819:2011 by local governments, make this a work in progress. Data capture Typically Vicmap relies heavily on the agreements and MoU’s signed with authoritative Custodians, through the DELWP Custodianship Program, for its data. Vicmap Address relies primarily on Local Government for address. For unincorporated areas authoritative Custodians are sought for each, such as Alpine resorts and shopping centres. Data maintenance Vicmap products can change under one of the following three terms: Vicmap maintenance - The incorporation of new data to an existing dataset via an M1, spatial change requests or scheduled Custodial supply. No changes are made to the data or object model, therefore does not require change management processes. Additions can be seen in the weekly Vicmap update. Vicmap Improvements – Changing existing data, example the moving of a feature or adding of attributes. Typically carried out as part of a project through the provision of new Custodial data requiring change management. Vicmap upgrades – Significant changes to a dataset that may see existing data over a large area replaced and/or may require the data model changed. Change management processes are applied. Approximately 5% of all maintenance advice notices processed are separately audited by DELWP to confirm accuracy, completeness and correctness in the capture process.

addresses will be retired All addresses will ultimately have the source field populated source_verified Date address was last verified against the defined source dataset. Supplements the source field, revealing the latest date the address was verified by the source. Although the address ufi_created date indicates the time of most recent modification. A ufi_created date of many years ago does not mean the address is incorrect, but promotes the likelihood of the validity being questioned. DATE 08/02/2009 is_primary Primary or secondary property address Local Government properties are assigned and identified by a single property address, but alternative or silent addresses are sometimes linked to properties for means of alternative access or future subdivision. is_primary options: Y = Yes, the property’s main (primary) address N = No, not the property’s main (primary) address. i.e. an alternative property (secondary) address Reference table : VMREFTAB.ADDRESS_IS_PRIMARY.IS PRIMARY_CODE property_status Indicates whether the address is associated with a “proposed” or “approved” property Currently linked to the associated VICMAP PROPERTY property and parcel record/s The parcel/property/address status is based on Land Registry’s approval of the relevant plan of subdivision. The parcel_status is mirrored in property_status in VMPROP, and subsequently carried through to the VICMAP ADDRESS property_status. property_status options:-: P = Proposed - indicates the plan of subdivision yet to be approved A = Approved - indicates the plan of subdivision approved (& certificate of titles issued) Reference table : VMREFTAB.PR_STATUS.STATUS_CODE
