VRM METHODOLOGY


The VRM methodology defines a scientific method developed by the Bureau of Land Management (BLM) in the USA – the impact of this management depends on the visual contrast created between a project and the existing landscape.

The Proposed Interim Code of Ethics for Landscape Visualisation (July 2003)1 states that professional presenters of realistic landscape visualisations are responsible for promoting full understanding of proposed landscape changes; providing an honest and neutral visual representation of the expected landscape, by seeking to avoid bias in responses and demonstrating the legitimacy of the visualisation process.

LANDSCAPE VISUALISATION PRINCIPLES

Presenters of landscape visualisations should adhere to the principles of:

  • Access to Information
  • Accuracy
  • Legitimacy
  • Representativeness
  • Visual Clarity
  • Interest

ETHICAL CONDUCT

The Code of Ethical Conduct states that the presenter should:

  • Demonstrate an appropriate level of qualifications and experience.
  • Use visualisation tools and media that are appropriate to the purpose.
  • Choose the appropriate level of realism.
  • Identify, collect and document supporting visual data available for or used in the visualisation process; conduct an on-site visual analysis to determine important issues and views.
  • Seek community input on viewpoints and landscape issues to address in the visualisations.
  • Provide the viewer with a reasonable choice of viewpoints, view directions, view angles, viewing conditions and time frames appropriate to the area being visualised.
  • Estimate and disclose the expected degree of error and uncertainty, indicating areas and possible visual consequences of the uncertainties.
  • Use more than one appropriate presentation mode and means of access for the affected public.
  • Present important non-visual information at the same time as the visual presentation, using a neutral delivery.
  • Avoid the use or the appearance of “sales” techniques or special effects.
  • Avoid seeking a particular response from the audience.
  • Provide information describing how the visualisation process was conducted and key decisions taken.
