New featureLucy (LuciadLightspeed)

The new TLcyS101FormatAddOn and TLcyLspS101FormatAddOn add-ons provide support for the S-101 hydrographic format:
  • TLcyS101FormatAddOn introduces core support to decode S-101 data, visualize it in a GXY view and change the S-101 display settings in the UI.
  • TLcyLspS101FormatAddOn extends the core support with visualization support in a Lightspeed view.
Both add-ons also provide workspace support, enabling users to store GXY and Lightspeed layers with S-101 data in a Lucy workspace, together with the currently used S-101 display settings. See the reference documentation of TLcdS101ModelDecoder for more information about the supported S-101 files.

New featureLucy (LuciadLightspeed)

Partial support for the APP-6E standard has been added to the TLcyAPP6AAddOn. Since APP-6E is only partially supported, APP-6D remains the default standard. You will need to switch the standard to APP-6E in the addon configuration in order to use the new standard. Read the How to switch between military symbologies in Lucy article for more information.

The supported APP-6E symbol sets are listed in the Supported standards article.

New featureDefense Symbology

We have added partial support for the military standard APP-6E. This update introduces the ability to create and visualize instances of TLcdEditableAPP6AObject for the APP-6E military standard.

APP-6E support is currently limited to the Cyberspace icon symbols. All supported symbol sets are listed in the supported military standards article.

You can visualize the supported symbols using the Military Symbology "Allsymbols" samples available for both GXY and Lightspeed.

Visualization of an S‑101 dataset in Lucy, delivered via a WMS service from LuciadFusion

Added support for the S-101 maritime data format. S-101 introduces several enhancements over S-57, aimed at improving the usability and functionality of electronic navigational charts in modern ECDIS systems. S-101 data can be visualized in a GXY or Lightspeed view in LuciadLightspeed, or can be served in a WM(T)S service in LuciadFusion.

For more details, see the S-101 related articles in the ECDIS entry in the Data Formats documentation section.

To ease identifying issues with spatial OGC Filter conditions, the filter evaluation logic now logs an info message if it does not have access to the Advanced GIS Engine component.

ImprovementLuciadLightspeed

  • TLcdGXYLocationListLabelingAlgorithm now supports defining separate shifts for the X and Y axes to move the label from the anchor point of the domain object in both directions with the respective shifts. As a result, new methods have been added to set and get the X and Y shifts separately:
    • setShiftLabelLocationX(int)
    • setShiftLabelLocationY(int)
    • getShiftLabelLocationX()
    • getShiftLabelLocationY()
    In addition, the following methods have been kept for backward compatibility but are now deprecated.
    • setShiftLabelLocation(int)
    • getShiftLabelLocation()
  • The TLcdGXYFixedOnPathLabelingAlgorithm is a new labeling algorithm added to support precise label placement along a path using flexible horizontal (LEFT, CENTER, RIGHT) and vertical (ABOVE, CENTER, BELOW) alignment options. The anchor point, defined by a relative path position (0.0–1.0), determines the label’s base location, while alignment and optional offsets adjust its position relative to that point without changing the anchor itself.

ImprovementLuciadLightspeed

Added API for GML 3.2/3.1 coordinate systems, which completes the ISO19115 metadata coordinate system API. This causes some ISO metadata methods to accept stricter arguments than before. For example, TLcdISO19115VerticalExtent#setVerticalCRS's argument type has changed from the generic TLcdGML32Definition to the more useful TLcdGML32AbstractCRS.
No mapping is provided to/from Luciad's coordinate system API.

The TLcdWFSClientModelEncoderFactory class has a new protected method createFeatureMetaDataProvider(ILcdOGCFeatureIDRetriever, TLcdWFSRequestContext). This method creates a TLcdFeatureMetaDataProvider, which is used to retrieve feature-specific information during the encoding of a WFS feature response to GeoJSON. You can override the method to customize the GeoJSON encoding of each feature, such as changing the name of a property.

The TLcd3DTilesProcessorBuilder can now apply a geometrical transformation on input data. The transformation should be passed as an affine transformation matrix using the preTransformFactory API method. This can be used to fix shifts, rotations and scale of the data. When using the MeshUp sample, you can read the transformation matrix from a .matrix file next to the data. The common use case of rotating a Y-up OBJ data set to Z-up has also been added to the MeshUp sample.

Upgrade considerationLucy (LuciadLightspeed)

TLcyJPIPDecoderAddOn and TLcyLspJPIPFormatAddOn have been deprecated (along with TLcdJPIPModelDecoder itself, see separate release note for more information). Consequently, these addons are no longer loaded by default, and workspaces that contain JPIP layers will no longer restore these layers when loaded. If needed, you can insert the addons back into config/lucy/addons_data.xml to re-enable the JPIP functionality.

The ILcdWFSServerModelEncoderFactory interface used by WFS-T services to create a model encoder capable of storing feature type changes (additions, removals, updates) in the data back-end has changed. The existing method

void createModelEncoder(ILcdModel)
