Verified views are specialist CGI’s created for planning purposes. A verified view is an accurate visual representation of a proposed development created by combining context photography and survey information resulting in an image that has verifiable visual accuracy. Verified views are specialist photomontages that can also be referred to as Accurate Visual Representations or AVR’s.
Our methodology for creating Verified views is compliant with the 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 and The London View Management Framework SPG (March 2012): Appendix C.
Final delivery of the exsiting/proposed images will be a high resolution pdf document and accompanied by a method statement outlining our production process.
Upon instruction we will research all image locations and liaise with any relevant parties with regards to gaining access. The number of Verified Views required and their locations are generally decided by the local authority or appointed townscape consultants.
The specified image locations are visited by our photographer, here they set up the camera ensuring that the camera is tripod mounted, leveled and capturing the agreed view. At this point we will note the camera specification, lens focal length and record an accurate fix on its geographic location. We will also note the date, time, weather, lighting conditions and direction of view. We use a full frame digital camera and have access to an array of prime lenses ensuring optimum image quality at capture.
We will appoint a trusted surveyor to visit each of the image locations to record a range of reference points visible in the proposed image view. These points are supplied geographically referenced against the Ordnance Survey National Grid coordinate system.
The captured images, survey data and metadata are used within our production flowline to create virtual cameras within a 3D space. The virtual camera settings are aligned with the real world camera used to capture the image backplate.
Proposed developments are either supplied in a 3D format or can be modeled by us from architectural drawings. The digital 3D model of the proposed scheme will be positioned to OSGB coordinates.
Using the matched virtual camera locations and other metadata we render the building model from the various specified locations. These rendered views of the development are then accurately composited with the original image backplates. Using photo editing software we then assure the rendered view sits correctly within its context, for example occluding any areas of the building not visible by using editing tools such as masks.
Before and After views of the proposed development from each of the specified locations are published in a high resolution pdf document. The document includes a detailed methodology outlining the techniques employed by us to create the Verified views. This document contains sufficient detail to allow for reliable comparisons between views within the same set and between our methodology and that employed by others.
