We employ a highly robust methodology that can be challenged at any time to confirm the proposal is accurately positioned within the photography.
In preparing the verified views, accurate photography is required, with survey information recorded, and an accurate model of the application parameters prepared. In simple terms, this allows a ‘virtual’ viewpoint to be constructed that accurately reflects an actual photograph, which in turn allows a wireline (representing the outline of the proposed development form) or fully rendered image of the proposed development to be accurately superimposed on the existing photograph.
The current practice guides this process and is informed by include:
• Landscape Institute Advice Note 01/11
• Guidelines on Landscape and Visual Impact Assessment 3rd edition (2013)
• London View Management Framework (March 2012)
1. Agree the viewpoints and level of AVR
2. Viewpoint photography and site survey
3. Produce panorama with photo correction
4. Model the proposal
5. Render out image from the 3D virtual camera
6. Apply foreground clipping
7. Formatted, identifying location and viewing distance
Depending on the nature of the view and the proposed development, an AVR can be a very simple block or wireline image or it can be a very detailed photorealistic image.
Appendix D of The London View Management Framework identifies 4 main types of AVR as shown
