GML v2.1.2 (Geography Markup Language) Feature Representation
In addition to the generic FME feature attributes that FME Workbench adds to all features (see About Feature Type Attributes), this format also adds format-specific attributes (Format Attributes).
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.
