In the new and much-anticipated Supplementary Planning Guidance - called the 'London View Management Framework' - Livingstone sets out 'definitive details' of the 11 existing viewing corridors.
As well as adding 'clarity to the London Plan' the Mayor's guidance also introduces a new protected 'view' of the Tower of London from the south bank of the Thames.
This news comes just days after Rafael Viñoly's controversial Walkie Talkie skyscraper in Fenchurch Street, close to the Tower of London, was given the green light by the government's new communities minister Hazel Blears.
According to the guidance, 'all parties involved in development within these 11 viewing corridors must take account of this guidance to ensure the landmarks within them are not obscured from stipulated viewing points'.
Meanwhile, the new document also introduces 17 riverside and 'other panoramic views' never before recognised under the previous view-protection arrangements.
It is understood these 17 panoramas will be protected in a slightly different way, where developments will only be permitted if 'it enhances the view and complements the existing landmarks'.
Livingstone said: `London's landmarks are cherished by Londoners and visitors to this great city.
'At present too much uncertainty surrounds the planning process and how we protect these views, leading to expensive public inquiries and costly delays.
'Together, the London Plan and this guidance will provide much-needed certainty for developers and planners. For the first time, this will help everyone to take a balanced view of development proposals, their impact on London's major landmarks and their contribution to the capital's character and identity,' he added.
