Examples with DefaultSampleDimension org.apache.sis.metadata.iso.content.DefaultSampleDimension used on opensource projects

Example 1 with DefaultSampleDimension

use of org.apache.sis.metadata.iso.content.DefaultSampleDimension in project sis by apache.

the class MetadataBuilder method addMaximumSampleValue.

/**
 * Adds a maximal value for the current sample dimension. If a maximal value was already defined, then
 * the new value will be set only if it is greater than the existing one. {@code NaN} values are ignored.
 * If a coverage contains more than one band, additional bands can be created by calling
 * {@link #newSampleDimension()} before to call this method.
 * Storage location is:
 *
 * <ul>
 *   <li>{@code metadata/contentInfo/attributeGroup/attribute/maxValue}</li>
 * </ul>
 *
 * @param value  the maximal value to add to the existing range of sample values, or {@code NaN} for no-operation.
