Lineage

Statement
Dataset Source: Vicmap Address was originally derived from address information held within Vicmap Property and Vicmap Transport. Sources within these two datasets include Melbourne Water's POLARIS rating database (metropolitan Melbourne addresses), municipal council records (rural and regional addresses) and similar authoritative sources such as water utilities. Significant updating and verification has vastly imnproved the content and detail. Dataset Originality: Derived 
Description
- The information was distilled from both Vicmap Property and Vicmap Roads and run though routines to match and compare the detail. - The results were analysed and categorised as to quality and reliability. - Based on the analysis, the resultant output was either channelled directly into Vicmap Address, set aside for varying degrees of validation prior to input into Vicmap Address or, as a final resort, deletion.

Quality

Attribute Quality
Comments
The allowable error in attribute accuracy ranges between a 1% (new data additions) to 5% (pre-PIP maintained contract data). For this project, attribute accuracy is a measure of the degree to which attribute values of address points agree with the information on the source material. 
Positional Accuracy
Comments
Geocodes within Vicmap Address are classified as 'BB' accuracy, ie, 90% of well-defined features are within 1mm, at plot scale, of their true position, eg, 1:500 equates to +/-0.5m and 1:25,000 to +/-25m. Anecdotal evidence suggests that the spatial accuracy of the major part of the dataset, at all scales, is frequently better than BB. Address points may vary in chosen geocode location :- - Rural Adddresses with a RRN - If property access captured, the address point varies from 1 to 50 metres back from the property road frontage. If the access to the property is from a road not abutting the property or through an adjacent property, the address point will be located outside the property and a 'outside_property' flag is set. If has been no access point location captured, the address point will be at the property centroid. - Rural addresses with no RRN - The address point will be at the property centroid. centroidnumberWhere a rural address access point is external to the property (eg end of a shared access track, a separate 'outside_property' flag is set. - Urban addresses in Metropolitan Melbourne - 8 metres back from centre of the property road frontage - Urban addresses in rural Victoria - Limited number 8 metres back from centre of the property road frontage, with the remainder at the property centroid. It is envisaged that all address points in rural Victoria, apart from RNN's, will be located 8 metres back from centre of the relevant property road frontage by mid 2008. 
Conceptual Consistency
Comments
The allowable error in logical consistency ranges between 1% (new data additions) to 5% (pre-PIP maintained contract data). Logical consistency is a measure of the degree to which data complies with the technical specification. The test procedures are a mixture of software scripts and on-screen, visual checks. 
Missing Data
Comments
Statewide coverage - varying levels of completeness depending on local government area. Approximately 94% of local government property address are held as primary addresses in VADD. There is a higher level of completeness in the Melbourne metropolitan area - 96% and with rural distance based addressing being approx 98%. Completeness Verification: A yearly audit, comparing local government addressing against Vicmap Addresss validates each address, populating the source=LGO (Local Govt Official) & source_ verified= "date" (of the currency of the Local Government audit data). At this time there has been minimal verification of addressing not assigned by Local Government. 
Excess Data
Comments
VICMAP Address contains the primary address for every property in VICMAP Property - a minimum of street_name and locality is populated. Addresses with a house_number have an address_class=S (Standard). There are approximately 360,000 addresses ( address_class = M) without a house _number, address_class=M (Misc).
