Positional Accuracy

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 40m tolerance was used on this dataset 

Lineage

Description

Level of detail reduced to suit 1:250,000 - 1:5 million scale range. Redundant attributes removed, Scale Use Code attribute added and populated. Number of verticies reduced using an enhanced Douglas and Peucker simplification algorithm.
