Zone of Theoretical Visibility (ZTV) analysis is an established and highly useful tool for undertaking landscape and visual assessments. Software and techniques have refined over the years and the accuracy of the data available to generate them is continually improving. However, they remain an under valued tool for use in site selection and early design stages. ZTV analysis can be a valuable tool for the early identification of potential visually sensitive locations. DRaW offer ZTV analysis as a standalone service, feel free to get in touch if this is something your projects may benefit from.
