Class UnifiedGridCoverage

java.lang.Object

javax.media.jai.PropertySourceImpl

org.geotools.coverage.AbstractCoverage

org.opentripplanner.graph_builder.module.ned.UnifiedGridCoverage

All Implemented Interfaces:

Serializable, javax.media.jai.PropertySource, org.opengis.coverage.Coverage

public class UnifiedGridCoverage
extends org.geotools.coverage.AbstractCoverage

Stitches together multiple elevation maps into a single elevation map, hackily. This is horrible, but the geotools way of doing things is too slow.

Constructor Detail

UnifiedGridCoverage

protected UnifiedGridCoverage(CharSequence name,
                              org.opengis.coverage.Coverage coverage,
                              List<VerticalDatum> datums)

It would be nice if we could construct this unified coverage with zero sub-coverages and add all sub-coverages in the same way. However, the superclass constructor (AbstractCoverage) needs a coverage to copy properties from. So the first sub-coverage needs to be passed in at construction time.
