Visualisation: An Approach to Knowledge Building

The chapter proposes the use of the Interactive Visualisation Tool (InViTo) as a method for sharing information by using spatial data visualisation, also known as geo-visualisation, applied to support spatial decision making and planning. InViTo is based on the idea that interacting with data can improve the users knowledge process, while visualisation should contribute to increase intuitive perception. Therefore, through the interactive and visual exploration of geo-referenced data, participants to spatial processes are supported to evaluate strategies and objectives for several alternative development options. The visual system works both on two-dimensional and three-dimensional views, so as to better meet users’ skills in interpreting images. InViTo has been used in different applications, with diverse purposes and spatial scopes, showing its effectiveness in creating a common language among the involved actors and enabling discussions on spatial development.
