|Verified Views / photomontages
Before and after images of a proposed development
These are accurately verified with use of survey and mapping data to correctly represent the scale and shape of proposals... The process involves the following:
- digital photography of existing views with a calibrated camera
- site survey of camera location and reference points in the view (or from other survey sources)
- accurate CAD modelling and rendering of proposals, using survey information to align correctly to the perspective of the existing photograph
Very accurate verified views are usually more often required for urban developments where skyline issues demand the highest level of accuracy but we are now using cloud point survey data for rural locations too.
|ZTV / ZVI Visibility Analysis
'Zones of Theoretical Visibility' is becoming more commonly used to describe the potential visual influence of a development in the context of the surrounding environment, as predicted by computer analysis. Data for surrounding building and woodland heights can be used and their screening effect is demonstrated by comparison of the visibility results with the bare-earth ZVI. Always a good starting point for desktop study of Landscape Visual Impact Assessment (LVIA)
Results can be represented most effectively in the following ways:
- a simple 'count' of visible points... suitable for turbines in a wind farm for example or lighting columns in a park and ride facility
- a colour banded plan in which the magnitude of visibility can be displayed... this can be the actual vertical heights of a proposed building visible, or the 'subtended angle' visible in the vertical field of view of the observer (please call and we'll explain!)
NEW! Landscape Visual Capacity
Finding how the landscape can accommodate new development is a relatively new process whereby we can interrogate a terrain model and produce a colour-map of the landform to predict the maximum height of new development that will NOT be seen from key sensitive areas - such as conservation areas, historic landscapes, or other sensitive receptors.
Capacity analysis has also been used to assist in site design of maximum building height parameters, based on what height the landform has capacity to hold to minimise the visibility of new buildings.
The opposite is also possible - to map the best locations for a new landmark, from where it will be seen best.
Popular with developers and designers to communicate the wider context of their proposals to planners and interested groups quickly and in a way which allows interaction and an iterative design process.
We combine height data with aerial photography to create a base digital terrain model (DTM), then we add proposals, from wind turbines to housing estates, with woodland planting to complete the picture - the model can be delivered online with a free 3D viewer to play on your computer - simply fly around over the landscape from your desktop
"I never believed it could be so useful"
Randall Thorp Landscape Architects, Manchester
We are particularly proud of the model we produced for Randall Thorp Landscape Architects and Peel Holdings. This was presented at a press meeting to show a fly-through of the proposals for the new racecourse, hotel, eco-village, equestrian and eventing facilities and golf course in the contect of existing open countryside and woodland in Salford
The model informed the design and planning process as well as becoming the basis for more detailed photomontages. It is still being updated and it's usefulness to the design team and for environmental impact assessment is well proven
Architectural Visualisation and Animation
Particularly effective for showcasing urban developments, architectural modelling can provide a high level of realism the subject matter lends itself more effectively to precise detailed modelling, lighting effects and shadow simulation.

A useful addition to wind farm photomontages is to animate the turbine rotors. This is a simple but effective method to demonstrate the effect of movement, since a moving turbine can easily catch the eye at a much greater distance than would be predicted by a static photomontage or wireframe view
