ImprovementTerrain Analysis Engine
The TEA sample service has been updated to make use of the LuciadFusion API to add additional service types.
TEA services can now be created within LuciadFusion Studio like all other services.
This means that the data in a TEA service no longer needs to be configured in a configuration file,
but instead uses data available within LuciadFusion Studio.

TLcdLOSCoverageFactory.createLOSCoverageContours now creates contours that wrap around if
the angle arc spans 360 degrees. It does this even if the angle step is not a divisor of 360.
2018.1
ImprovementTerrain Analysis Engine
In LOS calculations, the maximum radius and radius step implicitly define the radius sample distances.
These are the distances (in meters) from the center of the LOS coverage at which to sample to perform the calculations.
Now, radius sample distances can be configured directly via a new property on
TLspLOSProperties.
This allows you to use your own custom sampling scheme. For example, using small steps close to the center of the
coverage and larger steps farther away could help increase the total range without impacting performance and accuracy much.

Added TLcdLOSOptions object. This object allows you to configure certain aspects of the result of a propagation function
for our 3 main propagation-functions: TLcdLOSRadarPropagationFunction, TLcdLOSRadarPropagationFunctionSkyInBackground

low memory mode. This mode reduces memory used by TLcdLOSCoverageFactory while calculating LOS coverages, at a slight

TLcdLOSCoverageFactory has a new createLOSCoverageContours method, which takes two arrays

ImprovementTerrain Analysis Engine
TLcdLOSFactory and TLcdRadarCoverage have been enhanced. They have the ability to
- support center points in any reference,
- support terrain data in any reference,
- return LOS/radar rasters in any reference, with a pixel density independent of the underlying terrain data,
- return LOS/radar rasters which contain minimum or maximum or nearest neighbor values,
- return LOS/radar rasters which contain altitudes above terrain or above mean sea level (AMSL),
- control the sampling rate of the underlying terrain data.

The profile view and the vertical view support negative altitudes (depths).

Line-of-sight rasters now also create images. As a result they can now also be painted by no warp raster painters.

All heights greater than 32765 are regarded equal to 0. This has
an effect on line-of-sight computations when data is missing.

Several classes have updated and extended reference documentation (Javadoc).

TLcdGXYViewBasedTerrainElevationProvider did not take into account the
property 'UseOnlyVisibleLayers' correctly. This could cause a null pointer exception.

com.luciad.tea.TLcdVVTerrainProfileModel takes
into account multiple DTED rasters which are contained in the
same model.

com.luciad.tea.TLcdVVTerrainProfileModel takes
into account multiple DTED rasters. The profile is
displayed for all polyline segments which do not
cross raster boundaries.

When 2 contour levels computed with com.luciad.tea.TLcdContourFinder are exactly the same, the lower of the two was not painted.

Height contours based on raster maps can now be painted on maps.

com.luciad.tea.TLcdTerrainProfileController and com.luciad.tea.TLcdTerrainProfileUtil can now also take height values of non
visible layers into account.

Line-of-sight rasters can now take multiple DTED raster into account, part of the same layer or dispersed over several layers.

Line-of-sight rasters with a radius over 250 km were not painted. This was caused by an integer overflow.
