Remarks

Supported shape types: gisShapeTypePoint, gisShapeTypeMultiPoint, gisShapeTypeArc, gisShapeTypePolygon.

To filter a gml file based on feature layer and shape type, additional parameters must be added to the layer Name property in format : “Name;sublayer_name;shape_type_wkt” :

lv.Name = "Objects;buildings;POLYGON"

Available metadata keys:

Metadata Values Default Description
TGIS_LayerGML.AxisOrder NE EN EN Swap X and Y.
TGIS_LayerGML.FlattenXML YES NO NO Nested attributes names will be concatenated with _ separator.
TGIS_LayerGML.ForceCoordinateDimension 2 3 4 Force coordinate dimension when parsing coordinates

The layer axis order forced to be revered by:

  • changing AxisOrderReversed property
  • use Metadata TGIS_LayerGML.AxisOrderReversed=true
