Feedback Based Interactive Dynamic GIS Model for Landscape Evaluation

A feedback based interactive dynamic GIS model for landscape evaluation is proposed.The advantages of this model compared with the 4D-GIS model are also presented.The dynamic property of landscape is considered in this model adequately,and both the interactive behavior of designers and the interactive functions of the planning system are added into this model.Based on the feedback functions provided by the interactive ability of the planning system,designers can make real time control and revision to the landscape evaluation system to get a better landscape planning effect.An example is given to illuminate briefly the general planning workflow of the landscape evaluation system based on this model finally.
