Visibility Plans and Zones of Theoretical Visibility (ZTV)

Understanding where in the landscape a proposed development might be visible from can be a useful and sometimes critical tool in guiding developments and planning applications.   Our Landscape Architects regularly produce computer-generated plans showing the extent of visibility (or Zones of Theoretical Visibility – ZTV).

ZTVs can be produced for any project at any scale – whether a residential development, road or renewable energy scheme.  Outputs are produced on state of the art software using Digital Terrain Models (DTM) generated from Ordnance Survey data.  The models can also have further detail added such as main woodland blocks and settlements.

ZTVs are typically used to support Landscape and Visual Impact Assessments for planning applications, but can also be produced at early project stages to inform feasibility and site layout decisions.  ZTVs showing comparisons of existing and proposed theoretical visibility, and theoretical visibilities of a variety of potential roof or wind turbine  heights have proven useful tools in guiding development proposals.
