The Geospatial Forum will host a lecture by Christa Brelsford, a research scientist at the Los Alamos National Laboratory. Brelsford will present research exploring the causes, consequences and determinants of the urban built environment and urban heterogeneity. She will describe a handful of methods for quantifying urban heterogeneity; present an example of a multi-objective optimization framework for describing risk along hydrologic, economic and social dimensions; and then demonstrate an approach for quantifying trade-offs between different objectives when designing observation networks of the system.
