Mantle

Historically, delivering realistic terrain has been complex, slow, costly, and demanded specialized technical expertise. Without the right tools, terrain generation is a training bottleneck, requiring scarce specialists, significant time, and labor, often centralized. This results in high costs, rushed efforts for last-minute digital twin data, low reusability, and consequently, missed training or operational opportunities.

Mantle^TM allows anyone to rapidly prepare critical training, rehearsal, and mission digital environments – Supporting needs from quick-turn rehearsal spaces to high-detail simulations for ISR analysis. By making terrain generation easy and fast you get the tools needed to easily create and serve terrains to your critical systems, regardless of scale.

Key Capabilities

Point of Need Editing

Give non-technical users in operational teams the ability to build and stream terrain on the fly, at the point of need.

Agility for Mission Success

Immediately leverage terrains to prepare for operations, responding to events in-progress in minutes, not days.

Automation

Automate upstream data ingestion and use the procedural generation of repeated assets like vegetation, to reduce effort and increases speed of using terrain.

Cost-Efficient

Reduce manual labor and technical overhead with automation at every stage - from data ingestion to runtime deployment. One terrain can serve every stakeholder—training, ISR, planning, or analysis—without duplication of effort or versioning errors from siloed terrain creation processes.

Avoid Vendor Lock-in

Upstream data can come from any of your own, or commercial sources. Mantle is completely interoperable with the data needed for the mission, not just data from a single vendor.

One Comprehensive Package

Ingest, fuse, and stream terrains using one software package into VBS4 and Unreal Engine 5.6.

Easy-to-use Tooling

Anyone can instantly process and deploy live edits to features like roads, water bodies, or building placements.

Terrain Interoperability

Input and output data using common geospatial and OGC standards, including CDB, WMS/WMTS, One World Terrain (OWT/WFF), and Unreal Engine. Export to simulation and analytic tools such as Blender, MACE, QGIS, Steel Beasts Pro, Unreal, VBS3/VBS4, and Vega Prime.

Procedural Generation

Replace manual work with procedural tools that extrude building footprints from satellite imagery, place vegetation based on biome, and add seasonal changes to your terrain.

Serve Any Simulation

Stream the entire globe's accurate height maps, elevation, 3D buildings, transportation networks, and biomes/vegetation into VBS4, Unreal, and other simulation software.
