  1. 1. GIS in Decision Support: What it does in a classic sense is to “MODEL” SB 375 is a human value driven land use model • Human value driven models are a source of conflict • GIS is a land based modeling tool (land use decision support) • GIS inherently is a transparent modeling tool that can not only show you what values are but also show you where those values are 1. No person in this room wants or needs 375 to be a source of conflict 2. What everyone in this room wants is for 375 to result in more sustainable land use decisions that reduce potential carbon emissions Cal Poly PomonaC G I S R Center for Geographic Information Science Research
