GMJ Verified Views For Planning

GMJ pioneered ‘verified planning imagery’ as a new process in 1994. Combining survey data, photography and the 3D proposal model an accurate and verifiable image of the planned proposal can be generated.

Today, most major Central London planning projects require ‘verified imagery’ or as it is better known today ‘accurate visual representation’ (AVR) views for Townscape Visual Impact Documentation.

GMJ work alongside the architects, planning and townscape consultants from early in the design and planning process to help determine view locations, test the impact of different design options and provide 3D build parameter envelopes.

To produce  the rendered views GMJ interact closely with the architects and ensure that the materials and finishes employed accurately portray the quality of the design intent.

For the planning submission GMJ design and layout the required Townscape, Visual and Built Heritage Assessment Chapters that form part of the Planning Application documentation.


GMJ Views For Planning - Outline Step by Step Guide

Stage 1

Photography must be is natural and undistorted in terms of perspective. It must be level and corrected for vertical convergence. All  photographic details must be recorded and logged.

Stage 2

GMJ use medium format & 35 full frame digital camera systems for optimum resolution and clarity.

Stage 3

Specific lenses are used minimise perspective distortion and provide a horizontal view angle of approximately 40 degrees for a natural perspective.

Stage 4

Surveys of each photograph & location are recorded. A minimum of 10-15 points are recorded per photograph along with GPS readings of each.

Stage 5

The site photography and survey data are combined in a visualisation system ready for the 3D CAD scheme model/s.

Stage 6

The 3D CAD model is located within 3D environment and aligned to match the photography and survey data.


Stage 7

Material samples, supplied by the architects, are simulated and applied to the wire frame of the building.

Exterior lighting is a simulation of real world conditions and accurately positions the sun in the sky to match the photography. The photograph itself  functions as a light source within this configuration to create accurate colouration of the model and materials.




Stage 8

The completed render is opened in a post-production package (Adobe Photoshop) and further work is undertaken to create a finished image.

Foreground elements that should sit in front of the building are isolated and superimposed to set it visually into the scene, also atmospheric effects such as haze are added at this time.
