Method Detail

getIlluminationElevationAngle

@UML(identifier="illuminationElevationAngle",
     obligation=OPTIONAL,
     specification=ISO_19115)
Double 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)
Double 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.

Returns:
Conditions affected the image, or null if unknown.

getImageQualityCode

@UML(identifier="imageQualityCode",
     obligation=OPTIONAL,
     specification=ISO_19115)
Identifier getImageQualityCode()
Specifies the image quality.

Returns:
The image quality, or null if unknown.

getCloudCoverPercentage

@UML(identifier="cloudCoverPercentage",
     obligation=OPTIONAL,
     specification=ISO_19115)
Double 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 unknown.

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.

Returns:
The level of radiometric and geometric processing that has been applied, or null if unknown.
