The Acceleration Agency Leverages CesiumJS to Expand Port of Corpus Christi Active Digital Twin

For the Port of Corpus Christi, Texas, USA, managing security operations is a monumental task. The Port encompasses nearly 125 square miles, across both land and water, and directly owns close to 35,000 acres. This enormous footprint is spread over two counties with hundreds of facilities, vehicles, and vessels active at any time, and the Port relies on dozens of disparate digital systems for everything from vessel tracking to security.

With funding from a Department of Homeland Security grant to enhance critical infrastructure security, the Port brought on The Acceleration Agency (TAA) to build OPTICS, a 3D operational active digital twin that merges many of these systems into a single pane of glass and spatially organizes the data for true comprehensive situational awareness. TAA created both a desktop and mobile app for the Port that integrated live vessel traffic and computer aid dispatch with a geospatial model built using ArcGIS Maps SDK, giving port operators a realistic, real-time view of their environment.

This deployment served its purpose for internal teams; however, the Port is also looking to share this new fused dataset with security partners such as the United States Coast Guard. Deploying the app to external users during a crisis would be cumbersome: granting and revoking access to the secure application, which contains sensitive law enforcement data subject to FBI Criminal Justice Information Services (CJIS) requirements, created an administrative bottleneck. The port needed a solution that could be rapidly deployed to authorized external users on any device without requiring an installation, and that could also easily rescind access when needed.

The solution was CesiumJS. TAA developed Project Gemini, their Active Digital Twin platform and framework, which uses CesiumJS for geospatial visualization. The Port’s Active Digital Twin with CesiumJS is designed to give supervisors and dispatchers a better way to view various security-related operations in one single view, wherever they may be located. “Creating a mobile and web version allows us to put much of this data in the hands of officers in the field,” Keach said.

After years of investment in OPTICS, creating an entirely new, web-based 3D Active Digital Twin could have been daunting. But because CesiumJS embraces an open ecosystem and the ability to consume ArcGIS content out of the box, the team was able to directly ingest the Port’s existing ArcGIS Enterprise data. Rather than rebuilding the data pipeline from scratch, TAA used CesiumJS to bridge their existing geospatial data with what could be an easily shareable web environment.

The flexibility of open standards and community-driven development allowed TAA to develop a highly accessible web-based Active Digital Twin. When it’s complete, the Port of Corpus Christi will be able to use the CesiumJS Active Digital Twin to grant secure, temporary access to a real-time operational view during an emergency, empowering rapid, cross-agency collaboration in critical moments.

To get started with CesiumJS, experiment in Cesium Sandcastle, which has code examples and an AI-driven chat panel for support.
