Constructor Detail

NavigatedImage

public NavigatedImage(FunctionType function,
                      Set domain,
                      DateTime startTime,
                      String desc)
               throws VisADException

Construct a NavigatedImage without any data.

Parameters:

function - FunctionType for this image. It must have a domain with a NavigatedCoordinateSystem and a Range that has only one (Real) component.

domain - DomainSet for this image. The domain must have mappings to Latitude/Longitude and or have a NavigatedCoordinateSystem associated with it.

startTime - starting time of the image.

desc - description

Throws:

VisADException - couldn't create the NavigatedImage

NavigatedImage

Method Detail

getNavigation

public NavigatedCoordinateSystem getNavigation()

Get the coordinate system representing the navigation for the domain.

Specified by:

getNavigation in interface NavigatedField

Returns:

NavigatedCoordinateSystem for the domain of this field.

isNavigated

public boolean isNavigated()

Check to see if this image has a domain that can map to Latitude and Longitude.

Specified by:

isNavigated in interface SingleBandedImage

Overrides:

isNavigated in class SingleBandedImageImpl

Returns:

true if it has navigation, otherwise false

unary

public Data unary(int op,
                  MathType new_type,
                  int sampling_mode,
                  int error_mode)
           throws VisADException

return new NavigatedImage with value 'op this'

Specified by:

unary in interface Data

Overrides:

unary in class SingleBandedImageImpl

Parameters:

op - operation to perform (e.g., NOP, ABS, COS)

new_type - MathType of new object

sampling_mode - sampling mode to use (e.g., NEAREST_NEIGHBOR, WEIGHTED_AVERAGE)

error_mode - error estimate mode (e.g., NO_ERROR, DEPENDENT, independent)

Returns:

new FlatField corresponding to the requested operation

Throws:

VisADException - couldn't create new VisAD object
