Interface TimeCoding

All Known Implementing Classes:

ConstantTimeCoding, LineTimeCoding, PixelTimeCoding

public interface TimeCoding

The TimeCoding interface allows to convert pixel coordinates to time values and vice versa (if possible).

Since:

SNAP 2.0

Method Summary

Modifier and Type	Method and Description
default boolean	canGetPixelPos() Determines whether this TimeCoding is capable of converting time values into pixel positions.
double	getMJD(PixelPos pixelPos) Gets the time for a given pixel position as Modified Julian Day 2000 (MJD2000).
default PixelPos	getPixelPos(double mjd, PixelPos pixelPos) Gets a pixel position associated with a time value given as Modified Julian Day 2000 (MJD2000).

Method Detail

getMJD

double getMJD(PixelPos pixelPos)

Gets the time for a given pixel position as Modified Julian Day 2000 (MJD2000).

Parameters:

pixelPos - The pixel position in units of a given raster data node

Returns:

The time as Modified Julian Day 2000 (MJD2000).

canGetPixelPos

default boolean canGetPixelPos()

Determines whether this TimeCoding is capable of converting time values into pixel positions.

Returns:

true, if so.

getPixelPos(double, PixelPos)

getPixelPos

default PixelPos getPixelPos(double mjd,
                             PixelPos pixelPos)

Gets a pixel position associated with a time value given as Modified Julian Day 2000 (MJD2000).

Parameters:

mjd - The time as Modified Julian Day 2000 (MJD2000).

pixelPos - The pixel position to be modified and returned. If null a new instance will be created and returned.

Returns:

The pixel position, or null if this TimeCoding cannot compute pixel positions from time values.
