Photographic viewpoint schedule for a visual assessment
The viewpoint schedule is what makes a visual assessment checkable. Here is every field it should carry, and the conventions behind the photography.
A photographic viewpoint schedule is the table that makes a visual assessment checkable. It records, for every agreed viewpoint, where the camera stood, what it was pointing at, what equipment took the photograph and under what conditions. Without it a set of photomontages is a set of pictures. With it, a landscape officer or an inspector can stand in the same spot, hold the printed sheet at the stated distance and compare what they see with what you predicted.
Agreeing the viewpoints before you photograph anything
Viewpoint selection is the part of the process most often done in the wrong order. The sequence that works is to propose a long list with a plan and short justification, discuss it with the authority and any statutory consultee, then photograph the agreed set.
A sensible long list covers representative views from public rights of way, views from settlement edges and recognised receptors, views from designated landscapes where the site is visible, views that test the worst case rather than the most flattering, and any specific locations the authority has asked for in pre-application advice. Where a National Landscape, a conservation area or a registered park is in play, expect the relevant body to nominate viewpoints of its own.
Record the agreement. An email from the case officer confirming the final list, with the plan attached, belongs in the appendix of the Townscape and Visual Impact Assessment or the landscape assessment. It is the single most useful document when somebody later asks why a particular view is absent.
What the schedule records for each view
One row per viewpoint, with enough information for the view to be reoccupied by someone else.
| Field | Content |
|---|---|
| Viewpoint number | Sequential and used consistently across all drawings |
| Location description | Named place, path number, street or feature |
| Grid reference | Eastings and northings to the nearest metre |
| Camera height | Eye height above ground, normally 1.6 m |
| Direction of view | Bearing in degrees, with the horizontal field of view |
| Distance to site | Straight-line distance to the nearest point of the proposal |
| Date and time | Date and clock time of the photograph |
| Weather and visibility | Cloud cover, precipitation, estimated visibility |
| Camera and lens | Body, sensor format and focal length used |
| Receptor type | Residents, walkers, road users, visitors |
| Figure reference | The drawing number where the view is presented |
Two columns earn their keep more than the rest. The grid reference, because it lets anyone return to the spot with a phone. And the date and time, because it tells the reader whether the view was taken in leaf or out of leaf, which changes everything on a screened site.
Camera, lens and the standard focal length
The Landscape Institute's technical guidance on visual representation sets the convention most practitioners follow. A full frame camera with a 50 mm lens is the standard for single frame images, because the resulting image, printed at the right size and held at the right distance, approximates the scale of the view as the eye perceives it.
Where a wider view is needed, the usual approach is a sequence of overlapping frames taken on the same 50 mm lens from a levelled panoramic head, stitched into a cylindrical projection, rather than a single shot on a wide angle lens. A 24 mm frame flattens and distorts in a way that makes the development look smaller and more distant than it is, and a consultee who spots one will discount the whole set.
Record the sensor format explicitly. A 50 mm lens on a cropped sensor is not a 50 mm equivalent view, and a schedule that lists only the focal length leaves that ambiguity open.
Weather, season and time of day
Photographs should be taken in clear conditions with good visibility, because a hazy image hides the thing the assessment is about. Overcast but bright is often better than strong sun, which throws contrast and loses detail in shadow.
Season is a judgement that should be stated. Winter views, taken with deciduous trees out of leaf, show the worst case for screening and are what most authorities want for a scheme relying on existing vegetation. Summer views show the condition for most of the year. Many assessments present both for the viewpoints where vegetation is doing the screening work, and the schedule should make clear which is which.
Time of day matters where the sun's position affects visibility of the site, and where the scheme includes lighting. For a lit development, a night-time baseline photograph from the same position, with the camera settings recorded, is worth taking alongside the daytime set, and it pairs with the obtrusive light work described in the lighting assessment section outline.
Coordinates, bearings and eye height
Take the grid reference with a handheld GNSS receiver and note the stated accuracy. A smartphone reading is usually good enough for a view half a kilometre away and not good enough for a close view where a few metres changes the composition.
Eye height is conventionally 1.6 m above the ground, which approximates a standing adult. Where a view is taken from a first floor window, a footbridge or a vehicle, the height has to be recorded and justified. Bearings should be taken from the tripod position to the centre of the site, and stated in degrees from grid north rather than magnetic north, with the convention named.
Levelling is not optional. A tripod with a levelling base, checked for each frame, is what makes a panorama stitch without the horizon bowing.
Presentation sizes and viewing distances
A photomontage only means anything at the size and distance it was prepared for. The schedule and the figure sheets should state both, for example a 50 mm single frame printed at 390 mm width on A3, held at a comfortable arm's length.
Print the sheets. Assessors who review the whole set on a laptop at an arbitrary zoom level are not seeing what the methodology intended, and a drawing that carries a printed scale bar, a stated viewing distance and a north point keeps everyone honest.
Keeping the schedule auditable
Keep the raw image files with their original metadata, unedited, in a project archive. Keep the field notes. Keep the correspondence agreeing the viewpoints. If the application goes to appeal two years later and the inspector asks for the original of figure 14, you want to be able to produce it without hedging.
A short statement at the front of the schedule naming the photographer, the date range of the survey and the equipment used closes the loop. It also makes the authorship clear, which matters when the assessment is challenged. Where existing vegetation is doing the screening work, the same evidential discipline applies to the tree data, as the canopy cover worked example shows.
PlanScope drafts the structure and policy framing of a townscape and visual assessment, flagging the photography, the viewpoint schedule and the montage work as inputs to be supplied rather than inventing them. Browse the 66 report types to see where the visual evidence fits in your application pack, then have a landscape professional complete and review it.

Frequently asked questions
What focal length should be used for viewpoint photography?
A 50 mm lens on a full frame camera is the convention followed in the Landscape Institute technical guidance, because the printed image at the stated size and viewing distance approximates the scale of the view as perceived. Wider views are built from overlapping 50 mm frames on a levelled panoramic head rather than shot on a wide angle lens.
Should photographs be taken in winter or summer?
Winter views with deciduous trees out of leaf show the worst case for screening, and most authorities want them where the scheme relies on existing vegetation. Summer views show the condition for most of the year. Many assessments present both at the viewpoints where vegetation does the screening work, with the schedule stating which is which.
What eye height is used for viewpoint photography?
Conventionally 1.6 metres above ground, approximating a standing adult. Where a view is taken from a first floor window, a footbridge or inside a vehicle, the actual height must be recorded and justified in the schedule. Levelling the tripod for every frame is what allows a panorama to stitch without the horizon bowing.
Do viewpoints need to be agreed with the council?
They should be. Propose a long list with a plan and a short justification, discuss it with the case officer and any statutory consultee, then photograph the agreed set. Keep the confirming email and the plan in an appendix, because it is the document that answers any later question about why a particular view is missing.
Why does the schedule state a viewing distance?
Because a photomontage only reproduces the perceived scale of a view at the size and distance it was prepared for. A sheet marked with its printed width and intended viewing distance, plus a scale bar and north point, lets an assessor judge the image as the methodology intended rather than at an arbitrary zoom level on screen.
