Examples of org.opengis.feature.Feature

org.opengis.feature.Feature
An instance of {@link FeatureType} representing a geographic feature composed of geometricand non-geometric properties.
Beyond being a complex attribute, a feature contains the following additional information:
- A default geometry. To be used when drawing when nothing more specific has been provided.
- The bounds of all the geometric attributes of the feature
@see FeatureType @author Jody Garnett (Refractions Research) @author Justin Deoliveira (The Open Planning Project) @since GeoAPI 2.2 @source $URL$ @version 8.0

     * Computes the aggregated bounds of {@code features}, assuming all of them are in the same CRS
