Geoff Zeiss devoted over 30 years of his life to the Geospatial industry and global community,   focusing on utility and construction sectors, and mapping underground utility infrastructure among many other projects. Sadly, Geoff passed away in September of 2022.   The Geoff Zeiss Urban Infrastructure Mapping Fund was established to build on decades of innovation by Dr. Zeiss in developing effective and sustainable urban infrastructure through research and development supporting urban information systems.  The goals envisioned by Geoff include a focus on the creation of utility mapping, creation of infrastructure digital twins, and modernization of data workflows and interoperability in global construction and infrastructure management. This workshop will focus on working with the global community, through the SUMSF Conference, to co-design the specific strategies, objectives, projects, people, and resources needed to achieve Geoff's vision and build on his legacy.  The workshop will start with a brief overview of the Geoff Zeiss Urban Infrastructure Mapping program, followed by direct engagement with workshop participants to understand community priorities and identify specific opportunities to move the program forward.
