A digital walkthrough starts with a route selection and its visualisation by 3D modelling, videos or photographs. Several elements should be decided in this step: the detail level of the 3D model (or videos, photographs), and the theme & purpose of the walk.
During the walk
During the digital “walk”, a 3D model (or videos, series of pictures) of the selected route is presented to a certain number of participants at the same time. Or, participants can watch the video and pictures, or explore the 3D model individually by themselves. Participants can decide whenever and wherever they want to stop and record the required information. The information should be linked to the location on a digital map.
After the Walk
The tour ends with a discussion. The route is handled place by place; everyone presents their positive and negative observations, and can leave comments to others’. The discussion should be archived and compiled. It would be desirable to be able to check afterwards who said what, not necessarily on an individual detail information, but at least stating the age, gender, professional/layman, etc. Usually the topics that came up in the discussion are recorded on a digital flip chart.
