OS Open Map Local data is shown at the two largest scales to provide greater detail and more accurate building footprints. Road and place names are well attributed in this dataset, improving labeling. Spot heights, heritage sites, and public amenities were not included in order to limit map detail and labeling in favor of roads and buildings.
At scales 1:50,000 and smaller place names are not shown. Place names in OS Open Map Local were replaced by the Vector Map District place names at scales 1:50,000 and larger. At 1:50,000 Vector Map District roads are used in place of Strategi.
