Title

Vicmap Admin - Ward Polygon 2020 

Alternate title

WARD_2020 

Purpose

Vicmap Admin provides an accurate representation of various adminstrative boundaries across Victoria, at a capture scale of 1:25,000 or better. It is used in a variety of applications, particularly in emergency services, natural resource management, planning and development, and digital map publications. 

Supplemental Information

History: The WARD boundaries dataset for Victoria was established by the Department for Victorian Communities, Local Government Victoria. The Victorian Electoral Commission is contracted to review these boundaries on rotating 3 general election cycle in line with the Local Government Act 1989. Relationship to other Datasets: This layer is related to the LGA_POLYGON boundaries. No WARDS should cross an LGA boundary (excepting that there are slivers and overlaps currently within this dataset).

Statement

Dataset Source: WARD_2020 is directly extracted from the VEC¿s own Statewide Wards Master File. New extracts are triggered by changed ward boundaries from Electoral Representation Reviews or Subdivision Reviews. Updates for VicMap are normally sent in batches with several changes in one file. The boundaries in this update will be used for all the Councils holding elections in October 2020. Dataset Originality: Derived

Attribute Quality

Comments

Approx. 99%. The methodology used in the establishment of the WARDS was primarily a self-checking process. Further QA was done via a cycle of maps produced for shires. Maintenance of the WARD data set has been done at the Victorian Electoral Commission. 

Positional Accuracy

Comments

The boundaries of the 43 LGAs affected by 2020 electoral structure changes were aligned to the 2020 ADMIN_LGA (tab) dataset The external boundaries of the remaining LGAs are still aligned to the 2016 ADMIN_LGA (tab) dataset. The exception is Borough of Queenscliffe, for which the difference between the maritime boundary of the existing ward object and the maritime boundary for LGA_POLYGON is sufficiently large as to be visually distracting in such a small LGA. Internal boundaries are aligned to Vicmap Transport or Hydro primarily, or to Vicmap Property when no other features are available. Therefore the underlying accuracy is equivalent to the datasets it is aligned to. 

Conceptual Consistency

Comments

Topologically Structured. WARD boundaries may contain overlaps and slivers due to maintenance regime. Unincorporated areas are not included.
