What is a Verified View Survey?
Verified view surveys are a highly accurate, geo-referenced method used to produce photorealistic visual representations of proposed developments within existing environments. It combines survey-grade spatial data with high-resolution photography to create images that accurately depict how a planned structure or landscape modification will appear from specific, real-world viewpoints. They differ from a simple visualisation (CGI) in that they are grounded in georeferenced survey data and can be used as objective evidence to illustrate how a development will look from specific vantage points. They are therefore an essential component of many planning applications.
When do I need a Verified View Survey?
A verified view survey might be required whenever there is a need to illustrate how the massing of a proposed building will sit within the existing context. They are generally required as part of the planning process, especially in the case of proposals of significant height or scale, in heritage or conservation contexts, or where a strategic view might be involved.
Deliverables:
Outputs can vary by specification but include:
- Existing View (Baseline): A high-resolution, georeferenced photograph showing the site in its current state.
- Proposed View (The Montage): The 3D model of the development is accurately locked into the photograph. This is presented at one of the four Accurate Visual Representation (ARV) levels:
- AVR 0 (Yellow Outline): A simple line showing the maximum height and width.
- AVR 1 (Occlusion): A “shaded” wireframe showing what is hidden behind foreground objects.
- AVR 2 (Architectural Form): Showing shadows and basic design articulation.
- AVR 3 (Photorealistic): The highest level, showing materials, glass reflections, and realistic lighting.
