The Verified Views Checklist

You’ve mapped out your viewpoints, agreed on the AVR levels with the local planning authority, and commissioned your visualisation partner. The clock is ticking on your planning submission deadline, and then the email arrives requesting the "on-site survey data and asset packages."

If you haven’t coordinated a formal Verified View (AVR) before, looking at a visualisation studio's data request sheet can feel like reading a foreign language. Why do they need Ordnance Survey coordinates just to place a 3D model into a photograph?

Unlike standard marketing CGIs—where elements can be creatively tweaked to "look right"—verified views are bound by strict legal and mathematical tolerances. To achieve that bulletproof accuracy, your visualisation team needs a specific set of raw ingredients.

Here is the exact technical data your studio requires, why they need it, and how to prepare it to keep your project on schedule.

1. The Architectural Assets (The Proposed Scheme)

Before anything can be verified, the studio needs the exact digital blueprint of what is being built.

• What to provide: Clean 3D models exported as FBX, DWG, OBJ, or native Revit/Rhino files, alongside 2D architectural elevations and site plans.

• Why it matters: The 3D model must be a 1:1 structural match to the plans being submitted to the council. Pro-tip: Ensure your model is correctly geo-referenced to the absolute OS (Ordnance Survey) grid from the start. If the 3D model is floating in arbitrary virtual space, matching it to real-world coordinates becomes a massive technical headache.

2. The On-Site Survey Data (The Anchor Points)

This is the most critical piece of the puzzle. To prove to a planning committee that a building is precisely where you claim it is, the photo must be mathematically locked to the earth.

• What to provide: A digital survey file (usually a DWG) from a qualified land surveyor containing Total Station or GPS coordinate data.

• Why it matters: When your visualisation team goes on-site, they record the exact $X, Y, \text{and } Z$ coordinates of the camera. The surveyor then maps out fixed physical landmarks visible in the frame (like a church spire, a specific lamppost, or a curb corner). The visualisation studio imports these coordinates into their 3D software, matching the virtual camera to the real camera with millimetre precision.

3. High-Resolution Photography & Metadata Stamps

You can't build a verified view on a quick snapshot taken on a smartphone. The base photography requires professional-grade equipment and precise logging.

• What is captured: High-resolution photography taken on a full-frame sensor, typically using a fixed 50mm lens (which closest matches the perspective compression of the human eye).

• The hidden data: The studio will log the exact height of the tripod, the lens focal length, the orientation, and the precise time and date the shutter was pressed.

• Why it matters: To satisfy Landscape Institute TGN 06/19 standards, the studio must digitally replicate the exact real-world environment. Knowing the precise minute the photo was taken allows them to calculate astronomical sun angles, ensuring the digital shadows cast by your model perfectly match the real shadows in the photograph.

How to Keep Your Project Moving: A Timeline Checklist

To avoid bottlenecking your planning submission, follow this ideal data workflow:

• [ ] Step 1: Freeze the external massing and envelope of your 3D architectural model. (Internal fit-outs don't matter, but the shell must be final).

• [ ] Step 2: Instruct your land surveyor to capture the site coordinates and coordinate with your visualisation studio on the required "target points" before they take the background photos.

• [ ] Step 3: Deliver the material palette specifications (brick types, glazing reflectivity percentages) if you are aiming for an AVR Level 3, so texturing can begin immediately while the camera-matching is being computed.

The Takeaway

Gathering this data can feel like an extra hurdle, but it is exactly what transforms a standard piece of digital art into a legally defensible planning document. By preparing your geo-referenced models and survey data early, you guarantee a flawless, high-accuracy output that will stand up to any amount of council scrutiny.
