LuciadFusion Release notes

Resolved an index error that prevented the correct execution of the Database migration scripts when upgrading from LuciadFusion to 2026.0 on SQL Server databases.

• TLcdEllipsoidUtil#closestPointOnShape
• TLcdEllipsoidRhumblineUtil#closestPointOnShape
• TLcdSphereRhumblineUtil#closestPointOnShape

The Custom Properties of type STRING are now limited to a length of 650 character for MSSQL databases. This value now matches the maximum index key size limit that is imposed by MSSQL.

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.

• 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.

• If the map doesn't contain transparent pixels, the image/jpeg format is used, ensuring a fast encoding time and small payload.
• If the map contains transparent pixels, the image/png format is used.

• The specification now uses reusable enums.
• The names of the operations have been standardized and are now all unique.
• The security on each operation is now defined.
• The required property is now correctly set on the response schemas

The Custom Properties of type STRING are now limited to a length of 4000 character¹. If there are Custom Properties present in the database, these will be truncated when upgrading to 2026.0.

¹ for Oracle databases, this maximum length is 4000 bytes. The maximum amount of characters varies based on the amount of bytes each character uses according to the database character set.

void createModelEncoder(ILcdModel)

void createModelEncoder(ILcdModel, TLcdWFSRequestContext)

This new method signature allows implementations to take into account request parameters via the TLcdWFSRequestContext parameter.

Existing implementations can be updated by simply ignoring the new TLcdWFSRequestContext parameter.

• createWCSCapabilitiesProvider: is now abstract. It does no longer provide support backwards compatibility for the way of working from 2016 or before.
• Removed methods:
  • createCoverageOfferingList
  • createServiceMetaData

• ILcdWCSServiceMetadata: use ILcdWCSCapabilitiesProvider
• ILcdWCSModelEncoder: use ILcdWCSModelEncoderFactory
• ILcdCoverageOfferingList: use ILcdWCSCapabilitiesProvider
• TLcdCoverageOffering: use TLcdDefaultCoverageOffering
• TLcdCoverageOfferingDetail: use TLcdDefaultCoverageOfferingDetail

• Models: Handling raster data
• GXY Views: Visualizing raster data
• Lightspeed Views: Visualizing raster data

void encodeGXYView(ILcdGXYView, OutputStream)

String encodeGXYView(ILcdGXYView, OutputStream, ALcdRequestContext)

This new method signature allows implementations to take into account request parameters via the ALcdRequestContext parameter. Furthermore, implementations should now return the content type used by the encoding, allowing to dynamically choose the most appropriate encoding for a given view.

Existing implementations can be updated by simply returning the value of the getContentType() method. The new ALcdRequestContext parameter can be ignored.

• Added support for Revit and Navisworks 2026 files
• Fixes several issues related to reading geometry and metadata
