-----------------------------------
> Replace GridCoverage.evaluate(DirectPosition, …) method
> -------------------------------------------------------
>
> Key: SIS-485
> URL: https://issues.apache.org/jira/browse/SIS-485
> Project: Spatial Information Systems
> Issue Type: Task
> Components: Features
> Reporter: Martin Desruisseaux
> Assignee: Martin Desruisseaux
> Priority: Major
> Fix For: 1.1
>
>
> The following method has been added in the {{GridCoverage}} class in the
> development branch:
> {code:java}
> public double[] evaluate(final DirectPosition point, double[] buffer) throws
> CannotEvaluateException;
> {code}
> However this method is inefficient if invoked for more than one point (which
> is a typical scenario). It may trig many readings of small areas, construct
> many times the same {{CoordinateOperation}}, _etc._ Furthermore it does not
> allow users to control the interpolatipn method.
> An alternative approach could be to define a separated {{Evaluator}} class
> with methods for setting the interpolation types among other. All coordinates
> to evaluate could be specified in advance, allowing {{Evaluator}} to perform
> only one larger read operation instead than many small operations.
> We may keep {{GridCoverage.evaluate}} as a convenience method when there is
> really only one point to evaluate. But we would need to clarify at least the
> policy regarding interpolation method.
