noaa.coastwatch.util.BucketResamplingMapFactory

All Implemented Interfaces:

ResamplingMapFactory

public class BucketResamplingMapFactory
extends Object
implements ResamplingMapFactory

The BucketResamplingMapFactory class creates a resampling map by placing the source transform earth locations into buckets and searching the bucket contents for the closest data location to each earth location in the destination transform.

Constructor Details

BucketResamplingMapFactory

public BucketResamplingMapFactory(EarthTransform sourceTrans,
 EarthTransform destTrans,
 ResamplingSourceImp sourceImp)

Creates a new resampling factory from the source and destination transforms.

Parameters:

sourceTrans - the source earth transform.

destTrans - the destination earth transform.

sourceImp - the source-specific object to use for resampling queries.

Throws:

IllegalStateException - if the source transform had invalid earth locations when trying to determine its resolution.

Method Details

create

public ResamplingMap create(int[] start,
 int[] length)

Description copied from interface: ResamplingMapFactory

Creates a new resampling map that covers a specified set of destination coordinates.

Specified by:

create in interface ResamplingMapFactory

Parameters:

start - the starting rectangle coordinates in the destination space as [row, col].

length - the size of the rectangle in destination space as [rows, cols].

Returns:

a resampling object that covers the specified destination rectangle or null if the destination rectangle has no corresponding coordinates in the source space.
