| Geospatial Accuracy | For the TR_ROADS product attribute accuracy ranges between a 1% to 5% error. For this product attribute accuracy will be better since, the vast majority of data is composed of the higher class, ie (highways instead of minor back roads). 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 30m tolerance was used on this dataset |
