This Is VADE

An immersive XR platform in the works since 2021, VADE began as a proof of concept between simulation data company VRAI and the Royal Air Force for comprehensive situational awareness and could scale across Defence. VRAI announced VADE’s full release at DSEI in fall 2025. 

Real-world 3D data and live collaboration in VADE enable a common operating picture (COP) for detailed planning and faster decisions. Add XR, and troops familiarize themselves with a location before deploying. VADE can be set for individuals or in multiplayer mode, accessed via desktop app or with headsets.  

The tool’s capabilities span domains: 

For drone intervisibility studies, users can draw routes, mark waypoints at each kilometer, and determine blind spots at specific locations and heights to ensure proper placement anywhere on the globe.  

With a volumetric tool for battlespace management and deconfliction, airspace coordination via VADE is accurate and intuitive.  

High-altitude parachute insertion simulations include trackback lines for descent, giving the distance to the drop zone throughout the line; users can view the line from the aircraft or the ground, with the surroundings they can expect to see.  

Because VADE allows users to customize for NATO standards, slopes turn red if they’re not sufficient for helicopter landing sites (HLS). 

Although VADE is not a targeting tool, users can examine the impacts of explosives.

VADE employs Cesium World Terrain and Bing Maps Aerial imagery with Cesium for Unreal to enable users to navigate to places that matter for their missions, manipulating the time of day and simulating weather conditions, with high-fidelity rendering. When users are online, they can pull in Google Photorealistic 3D Tiles for exercises in urban areas, and Vexcel data is a boon when VADE is used as part of an airgapped solution via Cesium ion Self-Hosted.  

The VADE library includes data via Cesium ion; 3D models of aircraft, tanks, and other vehicles; NATO map marking symbols for friendly forces and enemy capabilities; and user-specific sources, like their own imagery, photogrammetry, or GitHub repos. VADE connects to users’ private Cesium ion accounts for hosting, tiling, and streaming efficiently. Using geospecific data via Cesium saves VRAI engineers and their users days of work per location and obviates the need for hand modeling or geotypical data, improving situational awareness and decision speed and reducing the cognitive burden on those tasked with complex planning and rehearsal. 

“It’s a transformative way of planning for defense. We operate in multiple dimensions—why wouldn’t we plan in multiple dimensions?” said Ant Casson, former Squadron Commander in the Royal Air Force and VRAI’s business development lead for the UK and Europe. “The possibilities are endless for VADE, enabled by the powerful tools provided by Cesium for Unreal.”

VRAI Delivers Virtual All-Domain Environment with Cesium for Unreal 

Large scale projects require massive coordinated efforts from many people across many businesses, whether that’s grading hundreds of acres for new suburbs, laying thousands of miles of pipelines, or hauling tens of thousands of cubic yards of dirt from quarries. Even minor errors can be costly, and sharing a common ground between the many teams involved is critical.  

Propeller supports users working at large scale sites: quarries, mines, earthworks, waste management, etc. Courtesy Propeller.

For users like these, Propeller provides the tools to perform frequent accurate drone surveys, process that data, and visualize the site. When this isn’t frequent enough, DirtMate brings near-real-time data into the mix. Propeller’s platform gives users an intuitive 3D model that’s recent, realistic, and accurate, so they can spot safety hazards, track earthworks progress, and measure reality against design plans to make calculated operational decisions around material, labor, and equipment needs. 

Propeller’s users perform drone scans of their sites and then visualize those scans in 3D with CesiumJS. Now, with support for IFC files as 3D Tiles, they’re able to compare designs against reality. Courtesy Propeller.

The heart of Propeller’s visualization is CesiumJS. Propeller was an early adopter of Cesium: for years they’ve been using Cesium’s open source software to visualize drone-captured surveys of earthworks, quarries, mines, and waste management sites. Propeller’s commitment to accuracy—reliably achieving geospatial accuracy within 3 cm—has made their platform trusted by professional surveyors. The sophisticated tooling they’ve brought into their platform, which they put into a simple form factor, makes advanced analysis accessible to anyone involved in the project, regardless of technical background.

Propeller users can see their project in accurate 3D. For pipelines, electric utilities, railways, and other long linear assets, the geospatial coordinate system in CesiumJS renders designs aligned with real-world curvature. Courtesy Propeller.

Propeller recently got an upgrade when its team incorporated Cesium’s Design Tiler into the platform. The Design Tiler takes complex BIM data, like the Industry Foundation Classes (IFC) open standard, and tiles it into 3D Tiles for efficient streaming. These improvements allow users to look at much more granular data, on a much larger scale, faster than ever.

"Integrating the Cesium Design Tiler into our platform has revolutionized our support for BIM for all our customers.” 

—Harry Morris, software engineer, Propeller

3D Tiles has made IFC files from one of the most cumbersome to one of the most performant file types on Propeller’s platform. This video shows first the original solution of an IFC model loaded in Propeller’s platform and then the same model tiled as 3D Tiles. Courtesy Propeller.

The tiling pipeline transformed IFC files—once cumbersome and limited to 300 MB—into one of the most performant file types on Propeller’s platform, which now supports IFC files up to 2 GB. This 6–7x increase in file size capacity came with dramatic performance gains. 

“For our customers with the most demanding projects, framerates are up anywhere from 20% to 170%, and memory usage has been drastically reduced, with our most demanding models seeing a 60x reduction in memory usage and similar reductions in data transfer," said Harry Morris, Propeller software engineer.

When streamed as 3D Tiles, IFC files retain all metadata: an inspector can click on an individual bolt in a bridge and see its size, manufacturer, the contractor responsible for installing it—whatever the users have uploaded. Courtesy Propeller.

Bringing Cesium’s Design Tiler into the platform took the Propeller team less than two months to roll out to full production deployment. When they released the new feature, the team also retroactively tiled all previously uploaded IFC files, delivering immediate value to their users without requiring re-uploads or workflow changes:

"Integrating the Cesium Design Tiler into our platform has revolutionized our support for BIM for all our customers. Cesium's expertise in the 3D Tiles open standard has delivered us a solution with greatly improved performance, accuracy, and feature richness—we've delivered highly requested features and given our construction customers confidence in an easy-to-use pipeline, revolutionizing their workflows," Morris said.

For Propeller’s users, streaming IFC files as 3D Tiles means a faster, higher quality experience. They can analyze large files, like viewing cross sections of this IFC model. Courtesy Propeller.

Reality Capture and Open Data at the Cesium Developer Conference

Siloed approaches to architecture, engineering, and construction (AEC) can lead to poor communication and collaboration across all phases of projects, resulting in delays and increased costs. DroneDeploy enables stakeholders to examine the entire life cycle of a project with its drone software and viewer, which use 3D Tiles and Cesium ion Self-Hosted to make massive photogrammetry datasets manageable and accessible.

DroneDeploy Map Engine

Founded in 2013, DroneDeploy has been using Cesium since 2018. With solutions for construction, agriculture, and insurance, DroneDeploy has built a platform for drone operators to host, visualize, and analyze their aerial imagery and photogrammetry, often on mobile devices. 3D comes into play for these users with accurate models and measurements of new schools or surveys for homeowners who are considering solar panels, for example. Teams can regularly refer to and update the models, examining change over time, making informed decisions, and staying on schedule.

The company has users in 180 countries, who have scanned 1.7 million jobsites, including 2D imagery and 3D models. It has the world’s largest drone data repository.

Operators run DroneDeploy’s software on their drones, capturing buildings and surroundings exactly as they are in the real world. This data is uploaded as aerial imagery or photogrammetry to DroneDeploy’s processing pipeline, which relies on Cesium’s 3D models tiler and point cloud tiler via Cesium ion Self-Hosted in their own environment, and is then available in DroneDeploy’s viewer for analysis and sharing.

Because users’ untiled models are multiple gigabytes, computers and networks might struggle with these massive datasets, especially phones or tablets. Using 3D Tiles means this data is optimized for streaming and designed for precision. 

“Customer datasets vary in size. For bigger datasets—like an entire construction site, multiple square kilometers—getting detail in an untiled model is nearly impossible. Tiling with Cesium allows us to get it in quickly and then refine while maintaining high quality and a high level of performance,” said Joseph Sullivan, DroneDeploy’s 3D engineering lead.

Cesium ion-WebODM Plugin

AERO AI rebuilt the Cesium plugin from the ground up, enabling the seamless integration of georeferenced ortho maps, point clouds, and 3D models generated in WebODM with Cesium ion. We removed the deprecated react-bootstrap dependency and implemented several API updates to improve overall functionality. We also resolved issues with dropdown buttons, refined styling with a cursor change, and refactored the modal usage. Our team fixed the file upload functionality in the UploadDialog and addressed text input issues. Plus we made adjustments to the task dialog, added logic to generate zip files for textured models, and updated the manifest plugin version while removing outdated dependencies. The full list of updates is here. Reach out to AERO AI with questions.

MathWorks/Cesium for Unreal

MathWorks, known for technical computing with MATLAB and model-based designs with Simulink, has provided basic airport scenes and permitted creation of a custom scene in previous integrations with Unreal Engine. Its R2023a release in March enables users to simulate flights in other portions of Earth and match the real-world location with Cesium for Unreal.

With Simulink, engineers access customizable models of aircraft or automobiles in Blocksets to see how various systems interact instead of hand-coding every aspect of the models and environments. Toolboxes build onto MATLAB to analyze data. The Aerospace Blockset provides Simulink reference examples and blocks to model aircraft and spacecraft. With UAV Toolbox, users can design, simulate, test, and deploy controls and autonomy algorithms for UAV applications. As of March, both of those offerings included integration with Cesium for Unreal to bring 3D geospatial data to their models and simulations.

Just as an accurate model of an aircraft is vital to training and simulation, so is accurate 3D geospatial context: flying (and landing!) in Boston is different from Kathmandu. MathWorks’ integration with Cesium for Unreal brings together high-quality models, high-fidelity graphics rendering, and geospecific representations of Earth. Cesium ion subscribers access curated 3D content and can host and tile their own massive datasets as 3D Tiles for streaming to Unreal Engine.

Among MathWorks’ many resources are tutorials for visualizing in Cesium and for flying the De Havilland Beaver, which includes modeling the bush plane and flying it through user-selected locations in Cesium for Unreal.

MathWorks Uses Cesium for Unreal to Enhance Aerospace Vehicle Simulations

Skydio, the unicorn startup building autonomous drones, has just released their newest product, Skydio 3D ScanTM, which brings greater autonomy to the drone market. 3D Scan simplifies drone operation, promising AI-powered flight planning that automatically creates an optimized path for data capture, as well as on-board computer vision so the drone can avoid obstacles and pick up where it left off after battery changes. 

A key piece of 3D Scan is the Edge Model Viewer, a feature built on Cesium that provides an instant view of the datasets produced by 3D Scan, allowing rapid field assessments. Whereas currently drone operators have to wait until they’re back in the office to review what they captured in flight, with the Edge Model Viewer, operators can check a low-polygon 3D model on a mobile device as soon as they land the drone. 

Skydio’s Edge Model Viewer allows users to see a low-polygon 3D model and their photos, all spatially indexed, as soon as they land the drone.

Quick review of a data capture drastically simplifies the workflow. That’s more nimbleness, fewer iterations, and improved captures. 

Law enforcement has only one chance to record an accident scene before cleanup begins, so seeing the data at the time of capture ensures nothing is missed. 

We learned more about the Edge Model Viewer from Skydio's lead engineer for the project, Rachel Basse:

"Working with Cesium has helped us turn 3D Scan's Edge Model Viewer feature into a game-changing customer experience. Being able to view 3D models in the field, even on a mobile device, is going to make a serious difference for our customers. We look forward to changing the game for drone inspection and mapping together!" 

Once satisfied with the data capture, the operator heads back to the office to download all the data from the flight, and export the photos to any photogrammetry tool. Many of those tools, including RealityCapture and ContextCapture, have integrations to Cesium ion, making it possible to view the photogrammetry data capture in 3D, together with geospatial context. 

Skydio 3D Scan makes it safer and easier to fly in tight spaces like this helicopter crash site.

Making drones simpler to fly means more people will be able to successfully use them. We’re proud to be part of that success as the drone data capture visualization platform of choice. To share your own drone data online, sign up for a free Cesium ion community account. 

Skydio’s Newest Autonomous Drone Software Brings Cesium to the Field

With high precision 3D visualization and measurement tools, global 3D terrain, and 3D Tiling that makes it possible to share even the largest 3D models, the Cesium platform supports unmanned aerial vehicle (UAV) projects from flight planning to real-time mission tracking to visualizing UAV-captured data.

Sky-Drones, an enterprise drone hardware and software company, is the latest UAV company to use Cesium in their real-time control and unmanned traffic management offerings.

Sky-Drones reduces the complexity for end users with full stack UAV avionic solutions, including both hardware and software. They specialize in the whole ecosystem of enhanced flight and ground control, encrypted communication systems, and cloud-based management for an organization’s entire fleet of UAVs.

Sky-Drones Cloud - Mission Planning in 3D

Cesium is an essential component of the Sky-Drones Cloud flight planning services. Instead of relying on elevation profiles to plan missions, pilots get an intuitive 3D view that allows them to visually create flight paths with interactive waypoints, all in the context of high resolution Cesium World Terrain. Terrain data is integrated with weather information and airspace data from Altitude Angel, helping pilots avoid ground hazards, manned flights, and other airspace restrictions.

Sky-Drones displays ground hazards, such as these power lines, to guide pilots in creating a safe flight path. Pilots can view the flight plan from any perspective: rotate, change view angle, tilt, view from surface and get back to orthogonal view.

Sky-Drones Cloud provides entire-fleet readings and status updates on one screen, with clear visuals as to where each drone has been, where its next mission is, and the type of terrain that will be encountered. Meanwhile, located in the same hub of information, flight hours, battery life, and real-time flights and flight logs provide the necessary information to maintain and service a vast fleet of drones.

Airspace data in the Cesium-based viewer provides a detailed picture of potential restrictions, such as airports.

Sky-Drones clients inspect industrial sites remotely, fertilize crops with precision, and make medical deliveries to hospitals fighting COVID-19. Police departments in the UK use UAVs, datalinks, and cloud services provided by Sky-Drones to quickly assess situations before sending in a secondary team. With better clarity in crowded environments, challenging terrain, and expansive rural areas, they’re better able to deliver an appropriate response.

Sky-Drones clients perform remote inspections, such as this cell tower inspection, which includes a stream of the drone’s video view in real time.

Cesium Supporting Remote Drone Operations and Unmanned Traffic Management with Sky-Drones

Every day, more than 100,000 commercial flights carry passengers around the world. At any given moment, you can see the real-time location of virtually all of those flights, not to mention a large portion of cargo and private flights, with Flightradar24, the premier flight tracking service.

Flightradar24 offers a wealth of data for plane enthusiasts watching the skies above them, for news outlets tracking air traffic incidents, and for ordinary people following the flights of friends and family.

Flightradar24’s 3D view, available in both the browser and mobile apps, is built with CesiumJS. The app shows the real-time location of flights, collected from terrestrial and satellite-based ADS-B transponders, radar, and more.

Planes are represented by a 3D model, which viewers can explore with a cockpit view, or from outside the plane, where they can pan and zoom to see the flight from any angle. When an aircraft is below 500 m, it also casts a shadow on the terrain below, calculated by the actual position of the sun at the time.

An aircraft in the 3D view cast shadows as they descend toward the airport.

Users can click on a flight to view details, such as flight number, speed, destination, altitude, and arrival time, as well as the data source. Viewers can see airports and other traffic, and can even switch flight paths.

In addition to the selected flight, users can see nearby aircraft.

Flightradar24’s real-time data provides vital information to millions of users every month—a use case Cesium was specifically designed to support. Learn how to build a 3D flight tracker like this, with real data from FlightRadar24.

UsPLM, with Cesium ion, is giving drone fleet managers the tools to keep drones flying as long and as safely as possible. With visualizations built on CesiumJS, their web-based software makes it easy to review mission performance over time and to quickly assess individual drones by examining high resolution digital twins.

Keeping an entire fleet of drones running involves numerous processes: asset tracking, operational overviews, flight logs analyses, mission planning, real-time simulation, forensics analysis, and regulatory compliance. UsPLM brings these many processes together with a focus on product lifecycle data management of unmanned aircrafts and their payloads.

CesiumJS powers two of these key elements: 3D Mission Review and 3D Asset Review. UsPLM says of working with Cesium:

“We have found CesiumJS such a powerful engine and ideal enabler to present and track drone fleet data at any granularity level as well as along the life cycle spectrum of any component.”

Time dynamic visualization for mission review

UsPLM’s Mission Review module combines their proprietary data analytics pipelines with CesiumJS’s time-dynamic data streaming capabilities to verify mission performance and conduct forensic analysis. Users can see historical performance of any given flight, shown in 3D over Cesium World Terrain.

PX4 is an open source autopilot for drones and other unmanned vehicles. As part of that ecosystem, Flight Reviewis a web service that allows anyone to upload drone flight logs. Flight Review displays interactive 2D plots of flight data, such as IMU sensor data, the vehicle’s orientation, or battery level. It also allows a user to view and replay the flight in 3D. Together, the 2D plots and the 3D view provide insights into what the vehicle was doing and help with finding problems and improving the flight software and vehicle setup.

The 3D view makes use of Cesium, including 3D terrain data. An overlay visualizes a remote control that is synchronized to the timeline and shows the pilot’s commands. Having the maps and 3D terrain helps to put the flight trajectory into perspective. The 3D view is useful to analyze crashes and reconstruct what happened as it is possible to pause, seek in time, and change the replay speed. Check out an example log.

Trendspek allows asset managers to digest ultra high resolution digital twins in their web browser. This allows inspections to be conducted remotely, boosting productivity and profitability for anyone responsible for the management or maintenance of physical assets. They create these high resolution datasets using refined capture techniques and aerial imagery acquired with drones.

Trendspek adopted Cesium to enable support of the 3D Tile specification. They have used Cesium to develop a range of incredibly powerful tools including measurements, annotations, and timeline viewers to compare tilesets. Users are able to extract an original full resolution image of any point in a tileset with a simple right click.

Trendspek builds a culture of collaboration using chat and messaging functionality. End users can comment, tag and respond to communications made about specific assets and even specific annotations. They aim to enhance predictive maintenance by closely monitoring trends and have built tools using Cesium that allow users to view models side by side and observe critical differences. Trendspek refines users’ understanding of an ever changing asset.

The ActiveFlight application shows current, historical, or simulated flight paths along with present or historical weather. Developed by the William J. Hughes Technical Center at the Federal Aviation Administration, ActiveFlight visualizes weather data alongside historical flight tracks, allowing usrs to analyze potential interactions.

To demonstrate how a flight interacted with the weather it encountered, ActiveFlight accesses a local proximity service that combines the flight position with a value ranging from 0 to 6, which represents its proximity to weather at that time.

Display of weather on the Cesium globe begins with accessing a service that delivers NetCDF or GRIB data files for various weather types, such as reflectivity, turbulence, or icing. After converting to either point cloud or batched 3D model with embedded glTF v2.0 formatted tiles, the 3D Tile resource is hosted as a local service. On the client side, upon request, the Cesium 3D Tiles API and Cesium3DTileset is used to access the url source of the tileset.json. An altitude property value used for declarative styling is embedded in each returned layer and allows the client to select the visibility of a single altitude layer or all layers at once.

To depict multiple simultaneous flights, the application uses Cesium’s SampledPositonProperty. Points along each flight path are modeled this way, allowing for the Cesium clock to control flight animations. Various weather products may be represented, not as flat images on the earth surface, but as layer data at their actual elevation.

New technologies such as 3D Tiles and the ability to create a 3D point cloud representation of weather data will be useful visualization tools in a variety of areas, including historical flight analysis, accident investigations, safety analysis, and research.

ActiveFlight: Multi-Layered Weather and Flight Path Visualization with 3D Tiles

Flights-pro is related to the Simpro-scene project. It uses Protege to represent knowledge and data and Rete4frames expert systems shell for intelligent information processing.

Flights-pro is both a simulator and an air traffic control system. It receives data on real air traffic from Flightradar-24, which is also powered by Cesium, and displays them on a 2D map in the browser window using Leaflet. Flights-pro performs analytics, such as determining whether an aircraft’s approach is dangerous, assessing the state of aircraft (e.g., take-off, landing, level), measuring the range to airports, and other tasks. The Flights-pro system allows users to plan and execute their own flights from one airport to another. In addition, users can make their own free-hand flight by piloting a plane from the cabin.

Flights-pro uses Cesium to represent the view from the cockpit. Users can be in the cockpit of any aircraft displayed on the map and can freely move from one plane to another. Also, users can view from the cabin in any direction (forward, backward, up, down, etc.). In addition to viewing the surrounding landscape, users can see other aircraft from the cockpit, which are shown as different colors and sizes. Users can control their own plane’s movements by entering data into the autopilot. The system can be used by pilots to study air traffic in the airport area and for training.

Users can adjust or further program the project, as shown on the project site.

Check out the examples on Sputnik Web, including Saint Petri Church in Sweden and Vyborg Castle in Russia.

Create 3D Models from Data Captured by Drones with Sputnik Web

Systems Toolkit (STK), created by Analytical Graphics, Inc. (AGI), is used to model complex systems for aerospace and defense applications. AGI’s Analytical Services uses STK Components to provide accurate time and coordinate representation as well as advanced analysis features such as route planning, visibility between objects, and communication and navigation analyses. Analytical Services provides an analytical back-end to any web-aware application, allowing for advanced analysis with simple web service calls. All of these apps demonstrate how to produce output in Cesium, bringing analysis to 3D visualization.

Analytical Services currently offers apps in the following areas. These demonstrate some of the functionality in Analytical Services.

The Unmanned Traffic Management (UTM) application provides UAV operators and planners an application that allows them to plan flights (both local and beyond visual line-of-sight) and monitor them in real-time. The Analytical Services provide REST interfaces that the UTM employs to assess planned or real-time flight routes for navigation errors, terrain intersections, and FAA airspace incursions.

The Communication System Link Budget service allows users to set up a transmitter, receiver, and any number of interference sources (jammers), each along any supported path, and receive link budget information for the receiver by time. This can help you understand where communication links are weaker and stronger.

With the Satellite Pass app, users can see details about satellites’ locations. They can view a satellite’s orbit over time, view a list of countries a satellite flies over, with entry and exit times, see when select satellites are within view, and see the pass visualized in Cesium. This demonstration application shows how you might use the Analytical Services Satellite Passes and Overflight web service calls.

The GPS Services app performs navigation accuracy calculations over a wide-range of options, including sites, routes, and search patterns. Users can view today’s maximum navigation accuracy over the entire world, view today’s current navigation accuracy using an animated heat map, and view all current GPS satellites, including their block type and current health status.

Analyze and Visualize Defense, and Intelligence Systems with AGI's Analytical Services

OneSky provides a fusion of web-based visualization with back-end API analytics to bring enhanced flight-planning and safety analytics to commercial drone operators. OneSky’s UAS Traffic Management (UTM) platform provides UAV operators and planners an application to plan flights (both local and beyond visual line-of-sight) and monitor them in real-time. Built on top of AGI’s Analytical Services, the OneSky UTM solution provides REST interfaces for users to assess planned or real-time flight routes and consider aspects such as navigation errors, communication link margins, and FAA airspace incursions.

Cesium’s 3D visualization brings a level of situational awareness to OneSky users that would otherwise be lost if only relying on 2D mapping solutions. Seeing the operational picture with 3D airspace volumes and terrain impacts helps users understand the real-world considerations that must be made when introducing their aircraft into the national airspace.

OneSky Brings Flight Planning and Safety Analysis to the Commercial Drone Industry

GeoFS started nearly six years ago. With the increasing quality of aerial images offered by Google Earth and as an aviation (and simulators) enthusiast, I felt frustrated that no flight simulator made good use of this data and decided to build my own. The goal of GeoFS was, and still is, to give users simple access to flying within these environments and the chance to enjoy the view. GeoFS grew more sophisticated as more people started to enjoy it, too. Today, it offers about sixteen aircraft ranging from the Piper Cub to Concorde and A380. Some aircraft are fitted with virtual cockpit rendering.

GeoFS is massively multi-player: users can see and chat with other players. Is also includes joystick support, autopilot, wind system, sound and light effects, replay mode, a map of restricted airspace, and a selection of over 30,000 referenced runways to take off from. The physics engine aims to be as realistic as possible while trying the keep the experience enjoyable for every skill level.

The application was originally built on top of the Google Earth plugin and has only recently been ported to Cesium. Porting to Cesium has been relatively straightforward. My code base abstracts enough of the underlying API to allow for an easy replacement. One of the best things resulting from the migration was that GeoFS now runs (and rather well) on mobile platforms. Running a native web technology is also much more logical and comfortable: using a Javascript debugger was a real burden with the NPAPI plugin but is as natural as it should be when using Cesium. Some major differences, however, led to some parts of GeoFS being entirely rewritten. For example, what are known as “Overlays” in the Google Earth plugin had to be replaced (this turned out to be for the best) with native HTML/CSS3 animations. Complex aviation instruments are being rendered with this technique, and performance was a concern but proved, eventually, to be very satisfactory.

Cesium is a relatively young platform, and the inevitable quirks had to be dealt with. But this is where the open source approach is making a real difference: I could easily browse through the code to understand problems, and even fix them myself if needed. And of course, much improvement and growth is expected in the near future. The API documentation has proven to be very good, and there are now plenty of examples to get inspiration from. Overall performance and stability are very satisfying, without much effort put into optimization.

Access Global, Photorealistic Flight Simulation with GeoFS

BridgeNet International, located in Newport Beach, California, provides consulting and software development services for airports and airport authorities around the world. Their services are primarily related to noise studies, analysis and reporting of aircraft operations near airports, flight procedure visualization, analysis and development, and the visualization of flight and noise data.

BridgeNet’s Volans software was developed in Java using NASA’s WorldWind to provide 3D display and analysis of procedures and flight operations for airports and airport authorities. However, the continuous advancement of browser capabilities and technologies has convinced them that browser-based applications will play an increasingly important role in providing simple and powerful solutions for their customers. To this end they are using Cesium to develop browser-based versions of their software that provide solutions accessible to anyone.

The Volans site for the San Francisco International Airport provides the public with an interactive tool used to view information about local aircraft operations and noise (both near real-time and historic). They have created similar sites for other airports including John Wayne Airport in Orange County, California and Heathrow Airport in London.
