A ZTV (sometimes known as a ZVI) is where you can ‘theoretically’ see an object from a given location. These are often used by Architects, Landscape Architects, Urban and Town Planners and Environmental experts for planning applications.
A ZTV is normally the pre-requisite to a full blown Verified View production. The idea is to narrow down the number of Verified View’s needed by running a Viewshed Analysis. The ZTV output is normally discussed by the planners and the client to decide which ‘views’ are most sensitive and then create a shortlist of Verified Views for production.
