Method Detail

getIlluminationElevationAngle

@UML(identifier="illuminationElevationAngle",
     obligation=OPTIONAL,
     specification=ISO_19115)
Number getIlluminationElevationAngle()

Illumination elevation measured in degrees clockwise from the target plane at intersection of the optical line of sight with the Earth’s surface. For images from a scanning device, refer to the centre pixel of the image.

Returns:

A value between -90° and +90°, or null if unspecified.

getIlluminationAzimuthAngle

@UML(identifier="illuminationAzimuthAngle",
     obligation=OPTIONAL,
     specification=ISO_19115)
Number getIlluminationAzimuthAngle()

Illumination azimuth measured in degrees clockwise from true north at the time the image is taken. For images from a scanning device, refer to the centre pixel of the image.

Returns:

A value between 0° and 360°, or null if unspecified.

getImagingCondition

@UML(identifier="imagingCondition",
     obligation=OPTIONAL,
     specification=ISO_19115)
ImagingCondition getImagingCondition()

Conditions affected the image.

getImageQualityCode

@UML(identifier="imageQualityCode",
     obligation=OPTIONAL,
     specification=ISO_19115)
Identifier getImageQualityCode()

Specifies the image quality.

getCloudCoverPercentage

@UML(identifier="cloudCoverPercentage",
     obligation=OPTIONAL,
     specification=ISO_19115)
Number getCloudCoverPercentage()

Area of the dataset obscured by clouds, expressed as a percentage of the spatial extent.

Returns:

A value between 0 and 100, or null if unknow.

getProcessingLevelCode

@UML(identifier="processingLevelCode",
     obligation=OPTIONAL,
     specification=ISO_19115)
Identifier getProcessingLevelCode()

Image distributor’s code that identifies the level of radiometric and geometric processing that has been applied.

getCompressionGenerationQuantity

@UML(identifier="compressionGenerationQuantity",
     obligation=OPTIONAL,
     specification=ISO_19115)
Integer getCompressionGenerationQuantity()
