Positional Accuracy:
Positional accuracy
Vicmap Property is classified as "BB" accuracy. That is, 90% of well-defined features are within 1mm (at plot scale) of their true position, eg 1:500 equates to +/- 0.5metre and 1:25,000 equates to +/- 25 metres. Anecdotal evidence suggests that the spatial accuracy of the major part of the data set (at all scales) is frequently better than BB.
Where subdivisions have been submitted in digital form, the "survey accurate" data has been used to extend the accuracy of the surrounding detail. This information has not been included in the precision attribute but a proposal is being considered to populate the precision value for every point that describes the cadastral boundaries.
Relative accuracy
No "shift" of data as a means of "cartographic enhancement" to facilitate presentation has been employed for any real world feature.
Atribute Accuracy:
For this product, feature and attribute accuracy is a measure of the degree to which the features and attribute values of spatial objects agree with the information on the source material. The allowable error in attribute accuracy ranges between a 1% (for new data additions) to 5% (for pre-maintenance contract data).
Logical Consistency:
Logical consistency is a measure of the degree to which data complies with the technical specification. The allowable error in logical consistency ranges between 3% (new data additions) to 5% (pre-maintenance contract data). The test procedures are a mixture of software scripts and on-screen, visual checks.
Data Source:
Vicmap Property is derived from what were originally two logically and physically separated databases. Melbourne Water created a digital data set covering the Melbourne Metropolitan area. Survey and Mapping Victoria created a similar data set covering rural Victoria. Both data sets consisted of "spaghetti" line work (that is, unintelligent data).
Neither data set was suited to GIS applications, as neither was "clean" in terms of line work, topologically-structured, or held any significant degree of "intelligence". The main level of "intelligence" linked to the data was through line style, colour, level, etc, and a feature code, data link which defined the scale origins and type of boundary represented.
The Metropolitan Base was created as a reference framework for Melbourne Water's assets and reflected Melbourne Water's business needs by holding subdivisions at both the proposed and approved stages. It focused on rateable properties and placed less emphasis on the cadastral changes that did not relate to 'property
Survey and Mapping's rural data set reflected a more basic view of land administration, comprising transferable parcels of land. This project entailed a complete re-compilation of the source data, being original Parish plans, registered plans of subdivision and VicRoads survey plans. The process required the production of pencil-plot compilations at a chosen scale of 1:2,500 over towns and built- up areas (using survey-acquired control) and 1:25,000 for the balance of the state (using existing standard Vicmap 1:25,000 topographic mapping as control). In a small number of areas, where existing base mapping could be used or where compilation at 1:25,000 was impractical (eg along the Murray River and parts of South Gippsland), mapping at 1:10,000 was produced. Where other authorities' (Local Government or Water Boards) mapping at similar or better scale and accuracy was found, it was adopted or upgraded and used in preference to producing new compilations
Both data sets were eventually brought under control of a single authority, that of the Office of Geographic Data Co-ordination (OGDC). Key challenges for OGDC were to provide a common structure to the data and to standardise the maintenance. Government restructures have since seen administration changes through Geographic Data Victoria (GDV) to Land Victoria, but management of the data has remained stable. Throughout this time, significant changes to the data (its structure, quality, content and maintenance) have occurred, one of the most noteworthy being the out-sourcing of data maintenance to a non-government agency. Whilst full control and administration of the data remains with Information Services Branch (ISB), Vicmap Property is now maintained by an external provider.
Other key changes to the property map base have included:
ˇ amalgamation of the two map bases;
ˇ translation into an OracleŽ data base environment;
ˇ line cleaning and topological;
ˇ the identification and rectification of many "gaps" found in the data (for example, missing survey plan notings, and incomplete identification of Crown land).
ˇ Restructuring of the data to correctly map real world parcel and property relationships
Improvements in the data continue, with improved input from local government and other key sources allowing faster turn-around of update information and added levels of attribution, for example Council property reference numbers.
