Feature attribute
A feature attribute is a an attribute referring to a geographic location. It refers to one or a sequence of coordinates.
Feature attributes are in use for vector data, referring to point, arc or polygon geometries.
For feature attributes it is advised to use the name: geometry. If another name is used, the feature attribute need to be configured for the vector domain unit with the following syntax:
unit<uint32> house
: DialogType = "**map**"
, DialogData = "**location**"
{
attribute<point_rd> location;
}
In this example the name location is used as feature attribute. As this is not the default name geometry, the configuration with the DialogType and DialogData properties is necessary.
The value type of a feature attribute is a value type from the PointGroup.
If the feature attribute is called (G)(g)eometry, the properties: DialogType and DialogData do not have to be configured (since version 7.206).
The composition type is
- not configured for point data items and
- arc or polygon for these types.
