Use limitation

Vicmap Buildings is available, under a DALA, to the Victorian public sector, Emergency Management sector and Local Government through a shared investment model via the Coordinated Imagery Program and can be found by searching the Victorian Government Data Directory. Non-government organisations will be able to access Vicmap Buildings through a network of Vicmap Data Service providers http://www.delwp.vic.gov.au/maps/spatial-data/victorian-spatial-data/licensing#DSP. Vicmap Buildings may also be made available for public viewing within Victorian Government web platforms (https://vic.digitaltwin.terria.io) , where the 3D building models can easily be integrated with relevant information held across government, providing richer information and insights. Currently Vicmap Buildings is publicly available in the Digital Twin Victoria Platform. The product will be searchable through https://datashare.maps.vic.gov.au or DataVic www.data.vic.gov.au

Purpose

Vicmap Buildings is a product that provides high level context of the built environment targeting a variety of applications, particularly to improve decision-making in a range of planning, environmental assessments, asset and risk management, and other spatial analyses.

Quality

Conceptual Consistency

The allowable error in attribute accuracy ranges between 1% to 5% error. Logical consistency is a measure of the degree to which data complies with the technical specification. The test procedures are a mixture of scripts, FME program and on-screen visual checks.

Attribute Quality

The allowable error in attribute accuracy ranges between a 1% allowable error to 5% error. For this product attribute accuracy ranges between a 1% to 5% error. For this product attribute accuracy is a measure of the degree to which features and attribute values of spatial objects agree with the information on the source material. 

Positional Accuracy

2D features have been extracted from 10cm imagery with 30cm horizontal accuracy for features on the ground. Building outlines are a depiction of the roof edges as they appear in the source imagery resulting in a maximum horizontal radial displacement (building lean) ratio of 2.5-1. A 20 metre high building with an extract Building Outline may be up to 8m offset from its true footprint location. Buildings with a height greater than 20m have had building lean manual corrected with various degrees of accuracy. Vertical accuracy of the extracted building model height varies between 0.5m > 1.0m. Building model heights are a generalisation of the building eave or maximum height. Accuracy stated refer to the accuracy of that approximation. Additionally building model heights have been extracted using source elevation data of different epoch to that of the source horizontal spatial data resulting in some known inaccuracies.
