WHAT ARE VERIFIED VIEWS?

Most architects and developers will be aware of architectural photo-montages: CGIs (computer generated images) that have been montaged into photographs to show how a future scheme might look like. There are many factors and variables that mean the visual accuracy of such images can be questionable.

Verified views are architectural photo-montages which have been created to a high level of verifiable accuracy using collected survey data, precise photography and a strict recorded methodology.

This methodology and data is detailed in the supporting document that we produce to accompany any such views.

 

ACCURATE VISUAL REPRESENTATIONS (AVR) CLASSIFICATION

AVR LEVEL 1

Location, size and degree of visibility of proposal

AVR2

AVR LEVEL 2

As level 1 + description of architectural form

AVR3

AVR LEVEL 3

As level 2 + use of materials

METHODOLOGY

Our methodology is compliant with relevant sections of: The Landscape Institute Guidelines for Landscape and Visual Impact Assessment: 3rd edition (April 2013); Landscape Institute Advice Note (January 2011) Photography and Photomontage in Landscape and Visual Impact Assessment; Technical Guidance Note 02/17 (31 March 2017): Visual representation of development proposals and, where appropriate, London Plan 2011 Implementation Framework (March 2012) London View Management Framework Supplementary Planning Guidance: Appendix C: Accurate Visual Representations.

Here is a basic overview of our approach:

BRIEF

We are asked to produce a selection of verified views. The location of the views is typically chosen through consultation with the local authority and required for a visual impact assessment report. Views are often provided in the form of draft photographs.

PHOTOGRAPHY

Verified photography requires careful planning and execution. We take high resolution images from each viewpoint and record a set of precise parameters including geographic location, elevation, heading, vertical position, lens focal length and sensor info.

SURVEY

Our surveyor visits the site to record a large range of reference points and the camera locations to ensure a high level of accuracy.

3D DIGITAL MODELLING

Using available design information such as architectural drawings or existing 3D data, we create a 3D digital model of the scheme.

RENDERING

5We import the survey data reference points and real world camera locations into our 3D model. We position virtual cameras within our model at the equivalent relative locations. We then render images from our ‘matched’ virtual cameras.

MONTAGE/COMPOSITE

6Using advanced photo editing software we accurately composite/montage the base photography and rendered images together and mask any elements of the render that would be occluded by intervening existing features.

DOCUMENTATION

7The before and after views for each viewpoint are presented in a detailed document that also includes information on: exact viewpoint locations, camera and lens type for each view, survey points, and our overall methodology for the creation of the images.
