Examples of net.opengis.gml.DirectPositionType

net.opengis.gml.DirectPositionType
A representation of the model object 'Direct Position Type'. DirectPosition instances hold the coordinates for a position within some coordinate reference system (CRS). Since DirectPositions, as data types, will often be included in larger objects (such as geometry elements) that have references to CRS, the "srsName" attribute will in general be missing, if this particular DirectPosition is included in a larger element with such a reference to a CRS. In this case, the CRS is implicitly assumed to take on the value of the containing object's CRS.
The following features are supported:
- {@link net.opengis.gml.DirectPositionType#getValue Value}
- {@link net.opengis.gml.DirectPositionType#getDimension Dimension}
