LineOfSightOperator.OutputVolumeEncodingRaster Property
Gets or sets whether the operator should output volume-encoding rasters.
Syntax
public System.Boolean OutputVolumeEncodingRaster { get; set; }Property Value
Default: Differs depending on type. See the table below.
Whether the operator should output volume-encoding rasters.
Default values
| Class | Default value |
|---|---|
| AirspaceCoverageOperator | false |
| LineOfSightOperator | false |
| TargetLineOfSightOperator | Not used. |
Remarks
When this property is True, the operator will output a special kind of raster features that encode volume information in an undocumented way. These raster features can only be used to send volume output from this operator to a VerticalProfileOperator, an IsolineOperator or an AirRouteOperator, three operators that can accept volume-encoding raster features but not mesh features.
To produce this kind of output, the operator will internally represent altitudes above sea level in meters as signed 16-bit integers, and the two largest such integers have special meanings, so the highest representable altitude is 32 765 meters above sea level.
The volume-encoding raster features will get a boolean attribute isVolumeEncodingRaster that will be True; this is sometimes useful for filtering. They will also have some attributes that are intended only for internal use in Carmenta Engine; these attributes have names that start with two underscore characters.
LineOfSightOperator
When it is a LineOfSightOperator that produces these raster features, they will also get copies of all the attributes of the corresponding observer feature (except for the special geoType attribute).
AirspaceCoverageOperator
For an AirspaceCoverageOperator, the volume-encoding rasters can represent the merged viewshed volume, or its complement, or both, depending on the mode property. An AirspaceCoverageOperator cannot copy attributes from observer features to the raster features, but each raster feature will get a boolean attribute acopComplement that tells whether it represents the complement, as well as a boolean attribute acopCoverage with the value False.
