South Africa provincial, regional and metropolitan route shields

[claysmalley]

Provincial routes have a green diamond shield with a white border and yellow text. Regional routes are the same, but rectangular. Despite the different shield appearance, these are both conflated with network=za:regional. Before we can add support for these route shields, route=road relations for provincial routes would need to have a separate network value, such as network=za:provincial.

Metropolitan municipalities can signpost their own routes, with M-prefixed numbers. Some cities have chosen to use unique shield designs, while others have opted for a simple rectangle identical to regional routes. Currently, only network=za:capetown is present in route=road relations, and routes for other cities are not completely mapped.

From left to right:

• Johannesburg-Ekurhuleni-Krugersdorp and Tshwane (Pretoria)
• Gqeberha (Port Elizabeth)
• eThekwini (Durban)
• Buffalo City (East London), Cape Town, Mangaung (Bloemfontein) and uMgungundlovu (Pietermaritzburg)

Note that directional signs show a prefixed route number in plain text in gold, without a shield:

But standalone trailblazer markers resemble the shields above, without an inline alphabetic prefix:
