Building Information Modeling (BIM) and Geographic Information Systems (GIS), as their names imply, are models of information at different scales that usually appear segregated. Our proposal is to integrate both scales of information in a Campus Information Model (CIM). This paper focuses on the description of this integration in terms of information and knowledge models, from the point of view of landscape design. We emphasize on the description of CLIM, an interactive tabletop we have developed to support collaboration and planning of landscape, which is constructed using models of information and knowledge to perform assessments, including quantitative aspects of effectiveness, efficiency and satisfaction of certain features of the Georgia Tech Campus.
