Vicmap Topographic Themes - Railway Infrastructure Point

dataset: VTT_RAIL_INFRASTRUCTURE
VTT_TR_RAIL_INFRASTRUCTURE is part of the Vicmap Topographic Themes (VTT) prooduct. This dataset is a superset of Vicmap Transport -TR_RAIL_INFRASTRUCTURE and includes the current and retired states of each feature instance. It supports feature versioning (RETIRE_DATE_UFI) and enables feature edit chaining (UFI_OLD). This layer is part of Vicmap Transport and contains lpoint features delineating railway features. Includes; Railway Stations, Rail Bridges, Tunnel-rail.

Description

Title
Vicmap Topographic Themes - Railway Infrastructure Point 
Alternate title
VTT_RAIL_INFRASTRUCTURE 
Resource Type
Dataset  
Purpose
Vicmap Transport provides an accurate representation of the Transport network across Victoria, at a capture scale ranging from 1:2,500 to 1:25,000. It is used in a variety of applications, particularly in emergency services, natural resource management, planning and development, and digital map publications. Data made available to Vicmap under Cross Border agreements is subject to the maintenance regime of the relevant jurisdiction and is not subject to the same maintenance regime of the Vicmap datasets. Cross border data made available in Vicmap is not updated regularly and was last updated in January 2012.

Lineage

Statement
Dataset Source: The line work and points were derived from the Vicmap Digital Topographic (VDT) map base coordinated by Information Services Branch (ISB) and its predecessors. VDT evolved from Victoria's printed 1:25,000 Topographic Map Series program together with the need to supply a control framework for the creation of the rural Digital Cadastral Mapbase. The capture scale ranges from 1:2,500 to 1:25,000 Statewide and the coverage, except for minor border issues is also statewide. Dataset Originality: Derived 
Description
Collection Method: Conversion of existing mapping, digital stereo capture 
Description
- Conversion of existing mapping - compilation conversion 30% and repromat conversion 50% - digital stereo capture - 20% -The majority of the conversion of existing mapping and approximately 30% of the digital stereo capture were outsourced to private contractors and the remainder was captured in house. Contractor's primarily scanned and vectorised existing repromat with a small amount of hand digitising done in some instances.

Quality

Attribute Quality
Comments
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
Comments
The line work and points are derived from the Vicmap Digital Topographic (VDT) map base coordinated by LIG. VDT has evolved from Victoria's printed 1:25,000 Topographic Map Series program together with the need to supply a control framework for the creation of the rural Digital Cadastral Mapbase. The capture scale is 1:25,000 Statewide and the coverage, except for minor border issues is also statewide. 
Conceptual Consistency
Comments
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, microstation MGE program and on-screen visual checks.
