Purpose

This annual change in lots and residential dwellings associated with housing development projects is one of two components of the housing development data suite (with the other being housing stock layers) that is an essential information resource for State Government housing and land monitoring functions. The data has been collected annually since 2004. The Projects dataset is consistent with and supported by the annual Stock dataset.

Quality

Conceptual Consistency

Logical data consistency tests were undertaken based on the known relationship between dataset attributes, and on the relationship between Stock and Project layers within the same year and 

Missing Data

Metro Melbourne and Geelong regions 

Attribute Quality

Housing development project related attributes are estimated to range in accuracy between 1% to 5% based on the processes used to capture these attributes, the source materials used, and consistency attribute tests with the housing project datasets. 

Positional Accuracy

Positional accuracy is consistent with that of the Vicmap Property dataset on which it is based, which 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. 

Lineage

Statement

Dataset Source: Colour aerial photography from DELWP for the period December to March has generally been used as the basis for identifying housing development activity. The Urban Development Program (UDP) dataset prepared and maintained by DELWP - Planning Division, and Vicmap Address, has been used to identify and assign attributes to multi-unit development projects. Dataset Originality: Primary
