Feature Representation
In addition to the generic FME feature attributes that FME Workbench adds to all features (see About Feature Attributes), this format adds the format-specific attributes described in this section.
The geometry of FME GML features may be identified by its xml_type attribute. The valid values for this attribute are:
xml_type |
Description |
xml_no_geom |
FME Feature with no geometry. |
xml_point |
Point feature. |
xml_line |
Linear feature. |
xml_area |
Areal feature, may be a donut. |
xml_text |
Text feature. |
Other attributes, including the feature’s feature type, are dependent on the mappings that are in an xfMap document.
No Geometry
xml_type: xml_no_geom
Features having their xml_type attribute set to xml_no_geom do not contain any geometry data.
Points
xml_type: xml_point
Features having their xml_type set to xml_point are single coordinate features.
Lines
xml_type: xml_line
Features having their xml_type set to xml_line are polyline features and have at least two coordinates.
Area
xml_type: xml_area
Features having their xml_type set to xml_area are either a single closed polyline feature (simple closed polygon), a donut, or an aggregate of donuts (and/or simple polygons). A simple closed polygon contains at least four coordinates, with the first and last coordinate being equal.
Text
xml_type: xml_text
These are annotation features.
