Federal & Defense

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.

French Air Force VR helicopter training

To minimize physical resources required for helicopter training and to properly prepare ahead of deployment, the French Air Force uses 3D geospatial data and collaboration in virtual reality. What do the terrain and buildings in a certain location look like? Should a pilot turn into the wind or away from it? How will the winch cables behave in different weather and at various altitudes? The French Air Force Heli Lab guides its trainees in answering those questions with accurate data at human scale, so they know what to do when they’re 40 meters above the ground.

The Heli Lab was created in 2019 with minimal funding, relying on free software and simulators with limited capabilities. Although this enabled the lab to imagine the possibilities for efficient training and begin work on its virtual reality program, the simulators could not communicate with troops on the ground, scenes had to be built from scratch, and locations were not precise, as they lacked a global map. 

The lab began using Unreal Engine and Cesium for Unreal to build their own platform in 2021, and in 2022 the team formally introduced the demo. With three people working full-time on the demo, the French Air Force’s helicopter VR training went from technology readiness level (TRL) 1, an idea, to TRL 9, operations, in the span of a year.

The Heli Lab taps into the French Air Force’s drone imagery and videos of an area of interest, using Reality Capture to build that part of the world in 3D. The team adds these high-res insets to Cesium World Terrain and Photorealistic 3D Tiles, accessed via Cesium ion SaaS and streamed as 3D Tiles to Unreal Engine; the lab is now shifting to Cesium ion Self-Hosted, to securely host classified areas. 3D models of rotary wing aircraft enhance the trainings’ authenticity, ensuring crews learn on the helicopters that are available to them. Cesium for Unreal pairs 3D geospatial data with Unreal Engine’s high-fidelity rendering power, making their VR training program smooth and accurate. 

With student servicemembers around the globe, learning with each other in simulation pods in France or via headsets in Gabon, having realistic training in a single accurate simulation is vital. The lab qualifies 18 pilots, 6-10 winch operators, and 6-10 medics each year. Current helicopter crew students are using the VR program as 30-50% of their training.

Initiatives like this one—starting from pockets of innovation from armed forces subject matter experts solving their challenges in a short loop by leveraging commercially available technologies—are beginning to take hold in service branches worldwide. 

The French Air Force adds high-res insets to Cesium World Terrain and Photorealistic 3D Tiles. Courtesy French Air Force.

The Heli Lab’s VR training program will enable other teams to add and share their own datasets, broadening the reach of the platform and improving training and mission planning across the French Air Force with accurate 3D data for next-gen education and preparation.

The UK’s Royal Air Force (RAF) has been preparing troops for some missions with immersive XR simulations in Cesium for Unreal.

RAF collaborated with VRAI to build its Virtual All-Domain Environment (VADE) mission planning and rehearsal system for both aircrews and operators on the ground. Defense planners can view operating areas, such as patrol routes, in typical light and with predictive weather conditions, providing critical situational awareness prior to deployment.

VADE began as a demo in 2021 and is still considered a proof of concept, but it was quickly applied to operational training—accurate, shareable 3D geospatial context enables better decisions. Users have been able to rehearse parachute assaults, visualize adversary equipment, and inspect potential evacuation routes at a 1:1 scale in XR, gaining a deeper understanding of locations and capabilities. VADE has been used in planning recent evacuations.

Through a suite of tools, users can rehearse parachute drops in VR in VADE, simulating the view they can expect to see through night vision goggles at their desired altitude. Courtesy UK Royal Air Force.

“How can I surmise this: through the darkness I was not met with the usual confusion of a compound I had imagined from above, but instead could instantly recognise the situation and orientate myself within milliseconds. One could argue this, on occasion, is the difference between success and failure,” said one VADE user.

Cesium ion enables VADE to be data agnostic, as the system can ingest various large datasets and render them in high fidelity quickly and accurately. Data from several sources comes together in VADE via Cesium for Unreal: Cesium World Terrain; Maxar Precision3D 3D Surface Model; imagery from Sentinel-2, Bing Maps Aerial, and the UK Ministry of Defence; Reveal Farsight models; photogrammetry from VRAI; and data from OpenStreetMap are hosted on Cesium ion On-Premises and tiled into 3D Tiles for streaming into Unreal Engine. With Cesium ion On-Prem, data is hosted offline and locally, ensuring security for RAF.

Coming December 2023, Cesium ion Self-Hosted features:

Delivery via Kubernetes to accelerate deployment and scalability

SAML-based user management to simplify integration

Same User Experience (UX) as Cesium ion's Software as a Service platform, including drag-and-drop ease of use

3D Tiles 1.1 generation for integration with Army One World Terrain data

Cesium Stories for dynamic, no-code presentations in 3D

As always, our included 3D Tiling Pipeline is engineered to produce the most optimized 3D tilesets for streaming, runtime visualization, and analytics.

Our new Reality Tiler for 3D photogrammetry and reality captures provides improved scalability, implicit tiling for optimized queries, KTX 2.0 compression for faster loading and decreased GPU memory usage, and enhanced coordinate reference system support for easier positioning on the globe.
