VIC DELWP - Vicmap Lite - Statewide Rail Network (Lines)

This dataset presents the footprint of linear railway features across Victoria. The linework was sourced from Vicmap Transport. The concept of a Scale Use Code has been introduced to help control the level of detail displayed.

Vicmap is the foundation that underlies most spatial information in Victoria. This portfolio of spatial related authoritative data products, made up from individual datasets, is developed and managed by the Department of Environment, Land, Water & Planning (DELWP). Vicmap Lite is a series of state-wide datasets that have been generalised and simplified to a useful scale of 1:250,000 and smaller. When used in conjunction with each other, the Vicmap Lite datasets are ideal for the creation of general topographic or thematic backgrounds.

Please note:

• The level of attribute information, the number of features and the number of vertices has been simplified to suit the 1:250,000 - 1:5,000,000 scale range
• The source linework was generalised using an enhanced Douglas and Peucker simplification algorithm. The algorithm keeps so-called critical points that depict the essential shape of a line and removes all other points. The algorithm connects the end nodes of an arc with a "trend line". The distance of each vertex to the trend line is measured perpendicularly. Vertices closer to the line than the tolerance are eliminated. A 30m tolerance was used on this dataset.
