This study integrated ecosystem services (ES) and 3D geo-visualization with urban design practices to inform future development in Pocatello, Idaho. Pocatello is a medium-sized city in southeastern Idaho that faces a range of challenges for sustainable future growth. It is important to understand what different urban designs can contribute to local ES. The objectives for this study were: building a 3D model for Pocatello Old Town, integrating key attributes in the model for planning and geodesign, visualizing in 3D using VR, and WebGL, and further, creating and analyzing the changes on local ES via future scenarios.The results showed that planting more treesand replacing impervious parking lots with green parking lots could reduce land surface temperature and improve air quality by removing particulate matter. With this approach, the decision makers in the City of Pocatello can analyze future scenarios both visually and statistically.
