Project Overview

As part of the Houseal Lavigne team, I contributed to an innovative digital twin project for the St. Louis Development Corporation, focusing on the Dr. Martin Luther King Drive corridor. This area, identified as a priority in the city's Economic Justice Action Plan, needed a modern approach to urban revitalization.

At Houseal Lavigne, I implemented ArcGIS Maps SDK for Unreal Engine to create an interactive 3D model of the city. This digital twin allows stakeholders to explore and visualize potential urban transformations in real-time, making complex planning concepts accessible to everyone.
