Additionally, a new runway surface type AM2 has been added to TLcdRunwaySurfaceType, representing a surface type consisting of metal planking.

The display names of the ELcdMS2525Standard enum values have been updates.

• Sectors that define their shape using a circle sector definition instead of an extent are now painted as arc bands, measured from the center point of the area. Previously, only sectors with an extent were painted.
• Sectors are now painted at the lower limit of their circle sector definition, which represents the altitude to stay above. The upper limit is used when no lower limit is available. Previously, only the upper limit was taken into account, causing sectors with only a lower limit to be painted on the terrain.
• The center point from which the sectors of an area are measured is now resolved for all feature types that AIXM 5.1(.1) allows an area to reference: a designated point, a navaid, a runway center line point, a touch down / lift off area, and an airport. The position is taken from the time slice that the time slice provider of the referenced feature returns.
• An area is now painted and labeled for a single time slice: the one returned by its time slice provider (TLcdAIXM51Feature#getDefaultTimeSliceProvider()), which represents the state of the area at the displayed time. Previously, all time slices of an area were painted and labeled, regardless of that provider, causing an area with multiple time slices to be drawn multiple times.
• Areas no longer lose their radius and angle labels. These labels are produced once per area, to avoid duplicates on an edge that two sectors share. Previously, the label texts that had been produced were remembered for the lifetime of the styler, causing an area to lose these labels when the same text had already been produced for another area or during an earlier styling pass.
• Sectors with a significant obstacle or a radius that is unknown, which AIXM 5.1(.1) expresses as a nil element, and sectors without a circle sector definition, no longer fail to paint with a NullPointerException. They are now painted using the information that is available.

The driver now refuses a connection whose requireAuth property excludes every authentication method, and rejects an empty requireAuth value. Replace such a value with the methods your server uses, for example requireAuth=scram-sha-256.

• VERTICAL_ANGLE: the vertical path angle that is published for the leg, in degrees.
• SPEED_LIMIT: the speed limit of the leg, as an ILcdISO19103Measure with the unit it is published in.
• SPEED_REFERENCE: the reference the speed limit applies to, such as indicated air speed, as a TLcdProcedureLegSpeedReference.
• BANK_ANGLE: the bank angle that is recommended for the leg, in degrees.
• ATC_REPORTING: the type of position report that an ATC unit requires at the leg, as a TLcdProcedureLegATCReporting.
• NAVIGATION_SYSTEM_TYPE and NAVIGATION_SYSTEM_IDENTIFIER: the navigation or radar system that the leg is to be flown on, for example a GNSS or an ILS.

It is now possible to configure the APP-6A and APP-6B "Antitank Ditch" symbols to be painted using the "Under Construction" stroke pattern. To paint these symbols using the "Under Construction" stroke pattern, set the ILcdAPP6ACoded.sTypeOfEquipment modifier to "U" or "Under Construction".

It is now possible to configure the APP-6A and APP-6B "Biological and Chemical Attack, Release Event" symbols to be painted using the "Chemical" icon. To paint these symbols using the "Chemical" icon, set the ILcdAPP6ACoded.sTypeOfEquipment modifier to "C" or "Chemical".

The APP-6E Cyberspace symbols now display the headquarters staff, feint/dummy and task force indicators when their hqTaskForceDummy modifier is set. Previously these indicators were missing.

In addition, the hqTaskForceDummy modifier now only offers the indicators that the APP-6E standard allows for the following symbol sets:

• Land Equipment (15): the headquarters and task force indicators are disabled.
• Land Installation (20): the task force indicator is disabled.
• Dismounted Individual (27): the headquarters and task force indicators are disabled.
• Activities (40): the feint/dummy and task force indicators are disabled.
• Cyberspace - Non Unit (64): the feint/dummy indicator is now enabled. Previously none of the indicators were available for this symbol set.

The APP-6E mined area symbols now display the feint/dummy indicator when their hqTaskForceDummy modifier is set to one of the Feint/Dummy values. Previously the indicator was missing, so a decoy area was indistinguishable from a real one.

The change affects the following APP-6E symbols:

• Minefield - Dynamic Depiction
• Mined Area
• Mined Area, Fenced

Fixed incorrect rendering of a number of APP-6A and APP-6B icons.

APP-6A:

• Hostile or Insurgent Infantry (2.X.3.1.15): now uses the Infantry icon, where it used to have the Motorised Infantry icon.

APP-6A and APP-6B:

• Hail (3.X.7.3): now uses the correct icon.
• Ice Pellets (3.X.7.4): now use the correct color.
• Ice Crystals (3.X.7.5): now use the correct color.
• Freezing Fog (3.X.9.2.1): now use the correct color.

APP-6B:

• Multi-Functional Earth Mover (1.X.3.2.2.3.2.1): now has a circular frame instead of a rectangular one when in the Friendly affiliation.

1. For local MBTiles files, an equally named Mapbox style file (.json) located alongside the MBTiles file is applied automatically.
2. Otherwise, the MBTiles metadata is checked for a STYLE property that references a Mapbox style. LuciadFusion uses this mechanism to advertise a style file associated with a published MBTiles data source.
3. If no style can be found, a default style is applied.

Visualization of an I3S dataset on a Lightspeed map — data: ODU GeoSEA, CC BY 4.0

Added support for the OGC Indexed 3D Scene Layers (I3S) data format. OGC I3S is an open community standard that defines a 3D content delivery format used to rapidly stream and distribute large volumes of 3D GIS data to mobile, web and desktop clients.

Additionally, a new runway surface type AM2 has been added to TLcdRunwaySurfaceType, representing a surface type consisting of metal planking.

We have added full support for the military standard 'APP-6 NATO Joint Military Symbology, Edition E Version 2, October 2025'.

The symbols of the Cyberspace symbol set, which we added previous minor release, LuciadLightspeed 2026.0, have been upgraded from APP-6E E Version 1 to APP-6E Version 2.

You can visualize the APP-6E symbols using the Military Symbology samples available for both GXY and Lightspeed. In a Lightspeed view, you can create a layer for these symbols with TLspAPP6ALayerBuilder. In a GXY view, you can paint them by setting a TLcdAPP6AGXYPainterProvider on your TLcdGXYLayer.

APP-6E - Fictional Scenario.

On NVidia GPUs, TLspViewBuilder now takes the GPU's video memory size into account when computing the default size of the OpenGL resource cache (#glResourceCacheSize()). This significantly improves the Lightspeed view's ability to load large datasets. In previous versions, the default cache size was usually overly conservative for modern GPUs with 8+ GB of memory.

The change reduces the need for users to manually adjust the cache size to alleviate performance issues. It only takes effect if the application does not explicitly set the cache size itself (either via the API or via the corresponding system property). On non-NVidia GPUs, the behavior is unchanged compared to previous LuciadLightspeed versions.

• setFirstArgument(Object)/getFirstArgument()
• setSecondArgument(Object)/getSecondArgument()

• setPropertyName(TLcdOGCPropertyName)/getPropertyName()
• setShape(ILcdShape)/getShape()

• Improved concurrency: downloading and decoding of tile payloads now happen on separate threads; larger thread pool for local data.
• Throttling of GPU data transfers for freshly downloaded tiles, to reduce frame drops during navigation.
• Improved prioritization of tile downloads based on camera position, and cancellation of downloads that become obsolete due to camera movement.
• Texture compression to reduce GPU memory usage and CPU-to-GPU data transfer volumes.
• Evaluation of the geometric error property is now DPI-aware.
• LPC point cloud layers no longer ignore the quality factor configured on the layer builder.
• Authentication can now be configured by annotating an ILcdPasswordProvider with @LcdService. It is no longer necessary to install a custom ILcdInputStreamFactory on the model decoder for this.
• Support for HTTP/2 if supported by the server; automatic fallback to HTTP/1.1 otherwise.

• TLcdDefaultModelModelTransformation
• TLcdDefaultModelXYWorldTransformation
• TLcdDefaultModelXYZWorldTransformation
• TLcdGeoReference2GeoReference

You can now configure the maximum expiry time for WFS-T feature locks with the wfs.maxLockExpiry servlet configuration parameter. The value is expressed in seconds and applies to locks created or refreshed by LockFeature and GetFeatureWithLock requests.

If a client requests an expiry value that exceeds this limit, the request is rejected with an InvalidParameterValue service exception report. The configured limit is also advertised as a maxExpiry constraint on the LockFeature and GetFeatureWithLock operations in the WFS GetCapabilities response, so that clients can find out about it up front.

• The LuciadLightspeed image processing framework uses a shared cache to store input, intermediate or processed data required by the imaging engine. The default size of this cache has been increased from 64 MB to 128 MB. This cache size can be configured by setting the system property com.luciad.imaging.maxCacheSize to a value in megabytes, e.g. -Dcom.luciad.imaging.maxCacheSize=64 to limit the cache size to 64 MB. Note that the cache should be large enough to fit at least all data that is being painted.
• The OpenCL imaging engine requires memory on the OpenCL device, typically a GPU, for its operation. It also uses a cache and its default size has been increased from 32 MB to 48 MB. This cache size can be configured by setting the system property com.luciad.imaging.engine.opencl.maxCLCacheSize to a value in megabytes, e.g. -Dcom.luciad.imaging.engine.opencl.maxCLCacheSize=32 to limit the cache size to 32 MB.
• The default size of the tile cache used by a height provider to read data from an image has been increased from 10 MB to 16 MB. This cache size can be configured when creating the height provider using the new cache size property on TLcdImageModelHeightProviderFactory or when creating a TLcdImageHeightProvider directly with the new builder. The maximal number of entries that can be stored in this cache has also been increased. You can configure it similarly to the cache size.

Set the com.luciad.fusion.wms.server.errorResponseOnPaintException system property to false to restore the previous behavior.

The hostile text modifier now accepts only two values: ENY (the default) and null.

You can use the modifier to disable the ENY indicator: setting it to null removes the annotation from both the icon label and the stroke decoration of tactical graphics. Previously, symbols with a hostile affiliation were always annotated with ENY, regardless of the modifier value.

The change affects all supported military symbology standards.

A number of control measure Line symbols in APP-6D and MIL-STD 2525D no longer display the generic PL ("phase line") label. Previously these symbols were labeled twice: once with PL followed by the first uniqueDesignation modifier, and once with the abbreviation specific to the symbol followed by the second uniqueDesignation modifier. They are now labeled only with their own abbreviation, followed by the first uniqueDesignation modifier.

The change affects the following symbols. All of them belong to symbol set 25 (Control Measure); the symbol code is given for each symbol.
