What’s New

Carmenta Engine 5.14

Carmenta Engine 5.14 is the latest version of our core technology. You can find new features in earlier releases further down this page.

Georeferenced Full Motion Video in 3D

The new Camera Projection Overlay makes it possible to display georeferenced full motion video streams in 3D GlobeView maps. This feature complements our existing, battle tested support for handling such video streams in traditional 2D maps.

The high resolution video streams can be draped in real time onto any 3D structures, including detailed 3D city models. Our efficient GPU implementation ensures that the frame rate stays smooth and that the CPU has time for other tasks.

Volumetric Line-of-Sight

The Line-of-Sight Operator has been extended with the ability to produce viewshed volumes that indicate which parts of its surrounding airspace an observer can see.

The volumes can be visualized in 3D GlobeView maps. They can also be cut through by the Vertical Profile analysis.

Additionally, the new Airspace Coverage Operator can be used to merge a number of such viewshed volumes into a combined volume that represents airspace covered by a sufficient number of observers. The operator can also be used to show the parts of an airspace that lacks sufficient coverage, as in the picture below.

Support for Reading Aeronautical Information Exchange Model (AIXM) Files

The new AIXM Dataset makes it possible to directly connect to aeronautical information in the XML based AIXM 5.1 and 5.1.1 formats that have been jointly developed by EUROCONTROL and FAA.

The picture below shows how information from an AIXM file can directly be visualized in the style of an Enroute Chart.

New API for Creating OGC GeoPackage Files

A new API makes it easier than ever to create and populate files in the standardized OGC GeoPackage format – an optimized, single-file container that is perfect for distribution to mobile devices.

The API supports writing both image pyramids, coverage pyramids and vector data to the GeoPackage, and any Carmenta Engine View, Layer, Operator or DataSet can be used as the data source.

Other Notable Improvements

New Feature Animation API on MemoryDataSet

New feature animation methods on MemoryDataSet makes it easy to smoothly move features along a 2D or 3D trajectory.

The API can also be used to animate feature transitions to a new position. This is useful to ensure a smooth behaviour even when receiving infrequent position updates.

Automatic Deactivation of Layers with Errors

The new “Disable on Error” functionality makes it possible to automatically deactivate layers that are not operational, e.g. due to unavailable map servers. This allows the rest of the map to continue to operate when such errors occur.

User Defined Color Tables for Radar Video

The Radar Video layer can now visualize the sweep intensity using a user-defined color table. This type of visualization is commonly used for weather radar presentation, as in the picture below.

Hardware Accelerated Effects for 3D Overlays

The hardware accelerated Effects concept that was introduced for map layers in Carmenta Engine 5.10 is now also available for 3D overlays such as line-of-sight, terrain warning and georeferenced video.

Improved Hardware Accelerated Rendering Configurability

A new Renderer Settings API makes it possible to configure the hardware accelerated rendering for greater visual fidelity on supporting hardware. It is e.g. possible to tweak the parameters for anisotropic filtering and multisample anti-aliasing.

Next Generation Terrain Routing

The Carmenta Engine off road routing functionality has received a major overhaul in this release. Not only have we been able to make the routing calculation significantly faster – we’ve also added several new features.

A major new addition is the possibility to calculate omnidirectional travel times from a specified starting point, resulting in so-called isochrones.

When the vehicle is using the road network, restrictions on vehicle width, height, length and weight can now be taken into account. The routing algorithm has additionally been extended to be able to handle areas that should be avoided but which are not completely forbidden.

It is now also possible to produce a more detailed representation of the calculated route suitable for generating textual driving instructions.

 

Automatic Detection of Ridges and Valleys

The new RidgeOperator can detect and generate features for ridges, valleys, peaks and basins from elevation data in any source and resolution.

 

New Mouse and Touch Interactions for Creating and Editing Circular Features

The built-in tools for mouse and touch interaction have been extended with support for creating and editing circles, rings, ellipses, circle segments and related features.

It is easy for the application to control which kinds of objects can be created and which types of interactions should be allowed.

 

Performance Improvements

The new release includes a number of different performance improvements applicable both to visualising and analysing data.
The viewshed algorithm used in LineOfSightOperator has been extensively parallelized and is now several times faster.

The DirectX renderer that is used in .NET WPF applications has significantly improved performance when rendering large amounts of similarly styled information such as complex road networks.

The TileLayer component now uses an even more efficient approach to read and render
its map tiles in parallel.

Other Notable Improvements

Support for Non-WMTS Tile Servers

The OgcWmtsLayer component can now be used to load tiles from tile-based map servers that do not implement the OGC WMTS standard, such as OpenStreetMap and Bing Maps.

 

Automatic Range Circle Generation

The new RangeCircleOperator makes it easy to generate and visualize multiple concentric circles, optionally combined with radial lines at defined directions.

The resulting “bullseyes” can either be centred on objects in the map or positioned relative to the screen.

 

Metadata according to GéoBase Défense and TopoBase Défense from IGN

Carmenta Engine can now read additional metadata according to the GéoBase Défense and TopoBase Défense standards specified by the French Institut Géographique National (IGN).

The metadata is easily accessible to the application through the existing DataSetInfo API.

 

New programming sample for NATO STANAG 4609 Full-Motion Video

The Projected Video application sample now includes an implementation of relevant parts of the MISB ST 0601.8 standard that is used in the STANAG 4609 standard for UAV digital motion imagery.

Hardware Accelerated Radar Intensity Displays

The new RadarVideoLayer makes it possible to create radar intensity displays by directly passing in the scan line data. The functionality complements our existing support for high-performance display of radar plots.

We have carefully designed the API to the new functionality to minimize the overhead when passing in scan lines, ensuring that the radar video can be updated in real time without slowing down the application.

The new hardware accelerated radar intensity displays are supported on all platforms (Windows, Linux and Android™).

New .NET Core Compatible API

Carmenta Engine 5.12 introduces a new .NET API that is compatible with .NET Standard 2.0 or later. This makes it possible to target .NET Core, Microsoft’s new, cross-platform .NET implementation. The new API is provided as NuGet packages and is supported on both Windows and Linux.

An included programming sample shows you how to use .NET Core and ASP.NET Core to create a Carmenta Engine powered geospatial micro service.


Improved Support for Thematic Data Sources

It is now possible to access so-called Raster Attribute Tables when reading thematic data such as land use databases.

The tables can contain additional information about the data classes such as human readable class descriptions or average heights for different vegetation classes.

Additionally, the VerticalProfileOperator has been extended with new inputs for thematic raster data and will use it to generate profile lines and polygons that use the same colour scheme as the raster.

More Flexible Corridor Generation

The two new operators CorridorOperator2D and CorridorOperator3D simplifies the task of generating corridor geometries around arbitrary lines.

The size, cross section, texturing etc. of the generated corridors is fully configurable.

Other Notable Improvements

MVT and MBTiles Support

The new MvtDataSet component makes it possible to connect directly to web services serving Mapbox Vector Tile (MVT) data.

The new data set can also be used to read local vector tiles data from MBTiles files.

 

New Formats for 3D Models

The Symbol3D component can now be used to load 3D models directly from the COLLADA, OpenFlight, glTF and OBJ 3D formats.

This eliminates cumbersome model conversion work.

 

Hardware Accelerated Rendering Improvements

Applications built using WPF, the Windows Presentation Foundation, now benefit from a new rendering engine based on DirectX 11. Among other things, the new renderer improves the support for hardware accelerated effects.

Both the OpenGL and DirectX renderers will now use background threads to transfer information to the graphics card to enable an even more stable frame rate.

 

Improved OGC WMTS performance

The OgcWmtsLayer component that is used to connect to OGC WMTS web services has significantly improved performance thanks to increased parallelism when loading map tiles.

Other major improvements include the ability to add full-text indexes to any vector data source to enable fast address and point of interest search and a new aggregation algorithm that can be used to declutter military tactical overlays based on the order of battle (ORBAT).

Read more

On-the-fly Terrain and Obstacle Clearance Calculation

The new VerticalClearanceOperator can be used to calculate the clearance of a flight route over terrain and vector obstacles. The high performance calculation is based on the same algorithms as Carmenta Engine’s existing vertical profile calculation, which makes it highly suitable for use in a dynamic scenario such as when interactively planning the route.

The output of the calculation is not only the clearance for each route leg, but also detailed information about the clearance for each obstacle, the highest points in the terrain etc.
This makes it possible to visualise the clearance in a very informative way. An example is provided below.

A route passing over mountainous terrain with various point and area obstacles. VerticalClearanceOperator is used to display terrain and obstacle clearance and to highlight dangerous areas.

 

IHO S-63 Nautical Chart Support

Automatic Aggregation of Hierarchical Data

The new AggregatingLayer can be used to declutter objects in a hierarchical structure, e.g. the ORBAT hierarchy of a tactical scenario. The aggregation can either be fully automatic – based on object overlap – or controlled by the application.

AggregatingLayer can also generate a graph of the hierarchical structure, as well as bounding polygons for each level in the hierarchy. Applications can use these features to further enhance the situational awareness for the end user.

An example of how AggregatingLayer can declutter a tactical overlay based on the ORBAT. With the same tactical situation shown in three different scales, AggregatingLayer automatically displays either individual teams, squads or the entire platoon.

 

Full-text Indexes

It is now possible to add full-text indexes to any Carmenta Engine vector dataset. This enables virtually instantaneous lookups of features based on free text search strings. Partial queries are supported and the results are ranked according to how well they match the search string.

A common use case for this functionality is to add address search functionality to an application, such as in the example below. But it can for example also be used to provide quick lookup of aeronautical features in an ARINC-424 database based on ICAO and IATA codes.

Carmenta Explorer, the Carmenta Engine map configuration viewer, uses the new full-text search index functionality to empower its “Find Features” user interface.

 

Native Support for connecting to OGC WFS Map Servers

A Web Feature Service (WFS), provides a way to request vector features from a map server. The interface is standardised by OGC, the Open Geospatial Consortium.

OGC WFS support is now part of the core of Carmenta Engine through the OgcWfsDataSet component. This complements the existing comprehensive support for OGC services in Carmenta Engine – it is also possible to connect to WMS, WMTS and WCS services, as well as to send queries to CSW catalogues.

As a Technical Committee member of the OGC, Carmenta is dedicated to using and promoting open standards. Carmenta Server, our feature-rich map server, also has full support for OGC WFS.

Other Notable Improvements

Map Package Extension

This extension makes it possible to package a mix of images, raster data (for example digital elevation models) and vector data into a single Map Package file.

Pregenerated spatial indexes and built-in low-resolution versions of the raster data ensure very efficient access to the package data. This is especially important for mobile devices where it is essential to minimize the amount of processing necessary to read and display data, but map packages work equally well in desktop and server installations.

Since they are single, self-contained files, map packages are easy to distribute and install. Packages can be generated from regular Carmenta Engine map configuration files using Carmenta Explorer, and are accessed using the new MapPackageDataSet class.

Carmenta is committed to ensuring that our products implement open standards whenever possible. The map package structure is aligned with the current draft OGC GeoPackage specification.

 

Optimized Caching of Dynamic Objects

A new mechanism in the OrdinaryLayer class supports efficient, hardware accelerated caching of dynamic features stored in a MemoryDataSet. This feature can drastically improve performance for map layers which contain large numbers of moving objects.

The new mechanism is enabled by setting the OrdinaryLayer.CacheMode property to Dynamic. Refer to the documentation of this property for more information on
how to use it.

 

Support for New Operating Systems

Carmenta Engine 5.4 is the first Carmenta Engine version that is available for Android. For more information, refer to the separate document “Introducing Carmenta Engine for Android”, available from carmenta.com.

Carmenta Engine is now also fully tested and supported on Microsoft Windows 8, both 32 and 64 bit versions.

Other Notable Improvements

Sharper Raster Data Rendering with OpenGL and DirectX

Improvements to the visualization of raster data using the hardware accelerated OpenGL and DirectX renderers have resulted in both significantly sharper maps and slightly reduced graphics card texture memory consumption.

 

Smoother Text Rendering for Moving Map Displays

 The new View.RenderingHint property can be used to change the way text labels are drawn in the map. When RenderingHint is set to MovingMap, texts will move more smoothly across the screen since they will not be aligned to the nearest pixel.

 

Batch scripts for easier deployment of Carmenta Engine Runtime

The Carmenta Engine SDK package now includes batch scripts which can be used to copy all required Carmenta Engine Runtime libraries to an application’s deployment folder. This makes it very easy to create so-called “XCOPY deployments”.

 

Support for Spherical Formulas for More Projections

Carmenta Engine can now detect and instantiate spherical reference ellipsoids for more types of coordinate reference system definitions. Spherical formulas are often used for meteorological data.
