Something that may be of interest to UK mappers is that OS VectorMap District has been upgraded from Alpha to Beta release.

Some of the new features:

Foreshore – the inter-tidal area has been created as a feature in its own right. This new polygon means you can show the sea up to either high or low tide level. In the alpha release this was just a white space between two lines.

Land polygons – a Land feature has been added to cover any land areas that are not a feature in the specification (e.g. farmland). This enables users to alter the colour of this feature.

Combined underground/over-ground railway stations - separate feature code created to give greater detail.

Places of worship – not in the alpha release, a selection of these now included.
