STK was released in 1989 to serve US and allied aerospace and defense organizations, and GDC will be available to STK users in July 2025. Users may create virtual worlds including buildings, terrain, and other physical structures. Subsequently, an infinite number of simulation configurations may be exercised, resulting in a significant reduction in the dependence on physical prototypes.

Using Cesium, GDC will replace Ansys’ Geospatial Content Server, removing the need to develop and maintain their own real-world data, tilers, and hosting solution.

“Being able to use Cesium ion Self-Hosted has saved a significant number of man hours that can be redirected towards additional ways to take advantage of the unprecedented access to data. We estimate the time savings to be the equivalent of half a full-time employee,” the Ansys team noted.  

Cesium has helped Ansys enhance mission modeling since 2011.

Cesium ion Self-Hosted provides hosting, tiling, and streaming for massive heterogeneous 3D geospatial datasets in users’ own clouds, data centers, or edge devices, enabling air-gapped solutions that meet strict security requirements and can be deployed to remote, disconnected environments.

GDC accesses Cesium World Terrain, Cesium World Bathymetry, Cesium OSM Buildings, Japan 3D Buildings and Terrain, and Cesium Moon Terrain via Cesium ion Self-Hosted. Accurate elevation data, depth data, and per-building metadata support planning and analysis in critical simulations. Cesium OSM Buildings are streamed as 3D Tiles in conjunction with Cesium World Terrain or Cesium World Bathymetry. Users can add their own datasets to be tiled into 3D Tiles for optimal streaming and visualization in STK.

Ansys Uses Cesium ion Self-Hosted for Geospatial Data Cloud

Our third installment highlights two more tracks at the 2025 Cesium Developer Conference: community-contributed aerospace and defense topics and sessions on Cesium, iTwin, OGC 3D Tiles, and other open technologies compiled by the teams at Cesium and Bentley Systems who work on them.

With Cesium’s roots in aerospace and commitment to interoperability and rapid innovation for tackling the hardest problems in 3D geospatial, we were excited to receive a group of full and lightning talk submissions focused on space, the Moon, flight systems, and mission-critical visualization and analysis.

To provide the community with a closer look into the advancements happening with Cesium and 3D Tiles, we decided to group a set of talks from the Platform team in Bentley Systems. The Platform team comprises development teams from Cesium, iTwin, and iTwin Capture, bringing together global geospatial, cloud-based-BIM (building information modeling), and reality capture.

Cesium ion SaaS and Cesium ion Self-Hosted utilize containers to provide Cesium ion. Containers are cloud-native, lightweight, and stand-alone software packages that include everything needed to run a piece of software: the code, runtime, system tools, libraries, and settings. This encapsulation ensures that the software runs consistently across various computing environments, from development to testing and production, regardless of the underlying infrastructure. At the heart of any container is the base image, and Cesium has recently updated base images to use the Red Hat Enterprise Linux Universal Base Image as deployed by Iron Bank. Because containers are smaller than virtual machines, it reduces the surface area to patch and update as part of the software stack. 

Containers are smaller than virtual machines, reducing the surface area to patch and update as part of the software stack.

Iron Bank was created and is maintained by the US Department of Defense (DoD)’s Platform One group. The goal of Iron Bank is to provide trusted and vetted container images that can speed up deployment of commercial and open source software across the DoD. This is possible because there is an open process by which images are created and because the images are continuously monitored and continually updated for Common Vulnerabilities and Exposures (CVEs) as part of the process that builds these images. Trust is an important part of what we do at Cesium, so it’s important that we are able to trust the source of our base container images and that our users are able to trust that we work to ensure a secure product for them. 

CVEs don’t exist only in the base image itself, although that is where most of them are found. To ensure we stay on top of security reports and prevent releasing vulnerabilities to our users, Cesium also scans for CVEs. CVEs are tracked through various internet databases, with contributions by companies, security researchers, and developers. CVEs generally are reported against software as they are discovered and can appear at any layer in your container—the operating system, your build tools, or your software dependencies. At Cesium, we use open source tools like Grype to identify CVEs and then mitigate them by constantly updating our dependencies or removing unnecessary pieces of software from our containers. We run these tools in our continuous integration/continuous deployment (CI/CD) pipelines, so that no release happens without security checks. 

Creating a trusted software supply chain 

Another important consideration that has received more attention lately is the software supply chain. People consuming software are now more concerned about where their software comes from, how it’s built, and what other software is packaged inside the software they bought. With Iron Bank as the base image, there is a known and open source of the bottom layers of the container stack, including the system libraries and programs that are built on top of the operating system. 

Additionally, Cesium takes great care to analyze the JavaScript libraries we’re directly dependent on, as well as those that may be nested inside, to ensure that we are looking at what licenses the software is bundled with, if it contains any vulnerabilities, and if there are updates we should be using. To do this, we generate a Software Bill of Materials (SBOM) using Syft, which analyzes not just the software we’re using but also the dependencies of that software. Using those SBOMs and a tool called Grant, we can determine what licenses our dependencies have so that we can avoid any unfavorable licenses. A full view of what this scanning looks like is illustrated below. 

In addition to monitoring for CVEs, Cesium also continually monitors our software for security vulnerabilities through Static Application Security Testing (SAST) and secret scanning. SAST analyzes application code to identify potential security vulnerabilities that can be mitigated prior to release. It looks for things like SQL injection, cross-site scripting, and buffer overflows. Secret scanning helps ensure that authentication parameters are not stored in the code, containers, configuration files, or other areas in the released product. The reports generated from these tools allow us to harden our code and provide assurances to users about the security of the Cesium ion environment. 

Software security can be hard, and it’s important to be vigilant and confident in the measures taken to ensure your software and your users’ data are secure. In addition to vetting our own software, vetting containers and their stacks can be very complex. Fortunately, we can rely on a solid base with Iron Bank and use sophisticated tools from the open source community to ensure that we are always following security best practices. 

Use Cesium ion Self-Hosted to support corporate policies or create air-gapped solutions that meet strict security requirements and can be deployed to remote, disconnected environments. Learn more about using Cesium in your own environment. 

Cesium ion Uses Iron Bank Container Images for Software Security 

Defense and other government agencies rely on current weather information, forecasts, and historical data for situational awareness and effective decision-making. The Weather Company (TWC) improves military training and planning by pairing its detailed weather data with geospatial context in apps using Cesium for Unreal and CesiumJS.

The Weather Company: Weatherverse

TWC was founded in the 1980s, addressing needs across various industries, and began serving government agencies in 2022. Sudden changes in weather conditions affect personnel and equipment, even with otherwise meticulous planning.  

Weatherverse Sim prepares warfighters with accurate 3D visualizations of environments and conditions—such as strong wind, more rain, or less cloud coverage—simulating weather they might face in the field. With recording and playback, trainees can experience and memorize scenarios for anywhere in the world, and trainers can adjust future sessions. Google Photorealistic 3D Tiles are streamed with data from TWC’s SUN Spatial Data Services and other sources for a comprehensive picture. Weatherverse Sim has used Cesium for Unreal since 2023 to bring realistic weather elements and geospecific terrain to these simulations, increasing operational effectiveness.

Weatherverse Planner monitors the forecast for locations important to planning teams and their missions, so they know what impacts weather will have on aviation, communications, infantry, and more. Users set thresholds and alerts for conditions like lightning, wind, or precipitation, for example, to make better informed decisions. Weatherverse Planner can be used as a stand-alone solution or integrated as a widget within any CesiumJS-based app for reliable performance on the web, streaming Bing Maps Aerial imagery for the view from space. Fusing weather data and geospatial context instead of managing multiple separate systems concurrently saves time and lives. Weatherverse Planner has used CesiumJS since 2024.

SimCentric’s CesiumJS-based SAF-Foresight app for planning and safety for live fire exercises will deploy Weatherverse Planner as a plugin for Exercise Talisman Sabre 2025. Exercise Talisman Sabre is the largest combined military training activity between Australia and the United States, with other partner nations joining, and this year it will incorporate real-time weather information to improve readiness. 

The Weather Company has built on top of CesiumJS as a plugin to further support and integrate Weatherverse Planner. The TWC-Cesium Plugin includes the protocols for acquiring, storing, querying, and filtering weather data from its SUN weather and spatial data services and integrates with existing Cesium-based apps. It is in an experimental phase. 

“Cesium provides a deep and rich set of capabilities, especially with regards to 3D orientation and geospatial data visualization. The framework is also well documented, approachable, and performant,” said J.R. Cottingham, senior director for The Weather Company’s Weatherverse.

Lockheed Martin JAM - Vista, CA, July 2024

While still in development, this capability is intended for state agencies to visualize and analyze active wildland fires; track flights of aerial assets that have been tasked with detection, monitoring, and suppression; and incorporate weather information, such as temperature, humidity, and wind.

The wildland fire incident list in the application is populated every 24 hours with information from the National Interagency Fire Center (NIFC), based in Boise, Idaho, USA, to ensure daily updates on the number and locations of active wildland fires. Imagery from National Oceanic and Atmospheric Administration’s (NOAA) Geostationary Operational Environmental Satellites (GOES) is pulled every 30 minutes. 

In an upcoming feature, Lockheed Martin’s AI will detect near-real-time fire hot spots from this imagery and reflect them atop 3D terrain from Cesium every 15-20 minutes. Lockheed Martin uses its “super resolution” AI capabilities to, in effect, add more pixels to the images, which refines them prior to determining the near-real-time fire area from the satellite imagery.

JAM brings together ground, air, and satellite data from NIFC, NOAA, and ADS-B flight trackers (as seen in the image above) and combines them in CesiumJS. State agencies might also have their own assets (e.g., thermal imaging from multi-mission aircrafts) that can be added. The application uses Cesium World Terrain and Bing Maps Aerial imagery streamed as 3D Tiles via Cesium ion, to provide incident commanders and staff an accurate 3D map to enhance the common operating picture. CesiumJS was built for interactive web apps and streaming massive amounts of data—it is lightweight and performant, vital for users receiving rapid updates in the field.

Work on the JAM prototype began in December 2023, and efforts on the current demo started in March 2024. Lockheed Martin, which employs 122,000 people worldwide, assigned five developers on this project. The company selected Cesium and its real-time update capabilities as an efficient, effective tool for visualizing historical wildland fire data. Lockheed Martin continues to leverage commercial partnerships to accelerate development of JAM.

Cesium's Inaugural 3D Geospatial Technical Exchange Meeting

To derive additional value from digital twins, Brightline Interactive’s SpatialCore platform pairs AI and the Cesium for Omniverse extension for spatial computing, empowering enterprise and public sector users to combine massive datasets and perform complex calculations. Spatial computing is the use of accelerated compute to analyze and process spatial data, in order to derive insights, make predictions, and perform calculations on one-for-one digital twins.

SpatialCore’s users face challenges in infrastructure, maintenance and operations, and training and simulation. As planners and engineers consider updating roads or building new ones, for example, they can use a SpatialCore-enabled digital twin to estimate how long a road will last, based on where the road is, what it’s made of, typical weather conditions, annual traffic estimates, the weight of those vehicles, and more. As the inputs change, so do the outputs, visualized and analyzed in immersive 3D.   

Rapid simulation and calculation enable swift decisions. AI is incorporated into NVIDIA Omniverse-powered workflows to aid calculations, reduce the required technical expertise of users, and train both humans and non-human assets (e.g., drones) with a realistic understanding of Earth. 

SpatialCore leverages open data sources and standards for compatibility with a wide range of data and tools. Universal Scene Description (OpenUSD), created by Pixar Animation Studios as an extensible ecosystem for 3D worlds, and 3D Tiles, the Open Geospatial Consortium community standard created by Cesium, are streamed together for precise, scalable 3D scenes for collaboration on a multitude of devices. 

Real-time collaboration connecting and empowering teams. Courtesy Brightline Interactive.

“Global enterprise requires a global substrate. In principle, we can’t do what we’re doing without Cesium ion,” said Tyler Gates, general manager of Brightline Interactive.

SpatialCore employs a variety of data sources and tools for its complete picture. Brightline adds its own datasets and those of its clients, such as point clouds from drone scans, to Cesium ion, for hosting in the cloud, tiling into 3D Tiles, and efficiently streaming growing collections of data to Omniverse-powered applications and workflows. 

SpatialCore also uses Cesium ion to access Google Maps Platform’s Photorealistic 3D Tiles for line-of-sight visualization and Cesium OSM Buildings for building metadata via the Cesium for Omniverse extension. An accurate, full-scale WGS84 globe is included in the extension and enables SpatialCore’s vital calculations and resulting simulations.

Cesium technology is a key component of the program focused on refining 3D Tiles, the Open Geospatial Consortium community standard created by Cesium for streaming massive heterogeneous 3D geospatial data. 

The One World Terrain Well Formed Format (WFF) is an extension of 3D Tiles, contributing to the program's goals of global accessibility and scalability, delivery of high resolution data, and interoperability. 

Cesium’s efforts towards the program include:

Further development of format capabilities 

Cesium is proud to contribute to providing foundational data like OWT and 3D Tiles, which enables warfighters to carry out operations on the same data used in analysis and planning.

Cesium has supported the OWT contract for nearly 5 years. To learn more about how Cesium can support your federal use case, contact me.
