Vicmap Lite - State Polygon
dataset:
VMLITE_VICTORIA_POLYGON
This layer is part of Vicmap Lite and contains polygons representing the mainland, islands and the sea. The polygons were
sourced from vmindex.fr_framework_area_polygon. The level of attribute information, the number of features and the number
of vertices has been simplified.
This version of the vmlite_victoria_polygon dataset was created by merging the previous layers vmlite_victoria_polygon_su2
and vmlite_victoria_polygon_su5.
The concept of a Scale Use Code has been introduced to help control the level of detail displayed.
Attribute scale_use_code values of 1 are suitable for display 1:2 million - 1:5 million scale range.
Attribute scale_use_code values of 3,4&5 are suitable for display 1:250,000 - 1:2 million scale range.

- The source line work 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 80m tolerance was used on this dataset
