TerraLens

TerraLens is a geospatial software development kit from Kongsberg Geospatial, a Canadian subsidiary of the Norwegian Kongsberg Group. It enables developers to build high-performance geospatial applications that display maps, terrain and real-time data in two and three dimensions. TerraLens has a long heritage in defence, aerospace and security, where operators require situational awareness displays that remain responsive while rendering large volumes of rapidly changing information, such as tracks from radars and sensors. General-purpose mapping libraries often struggle to meet these performance, accuracy and certification requirements. TerraLens addresses this by providing a mature, optimised rendering engine and a comprehensive set of APIs that allow system integrators to build mission-critical applications for command and control, air traffic management, unmanned systems and related domains.

Key features include support for a wide range of map and elevation formats, including military standards such as DTED, CADRG and CIB alongside common commercial formats, 2D and 3D rendering with smooth transitions, and the ability to display large numbers of moving objects in real time. Video overlays allow live sensor or drone footage to be combined with map data, and symbology support includes military standards such as MIL-STD-2525. The SDK provides tools for terrain analysis, line-of-sight calculations, measurement and annotations, and can operate in disconnected environments without internet access, which is important for deployed and secure systems. TerraLens is available for multiple operating systems and programming environments, including C++, .NET and Java. Its target users are defence contractors, government agencies, aerospace companies, public safety organisations and developers of uncrewed aircraft and maritime systems that need proven, performant geospatial visualisation embedded within their own applications. Licensing is typically tailored to development and deployment needs. Pricing starts from around USD 5,000; neither a free trial nor a free version is offered.
