Danish UFO Feature Representation

ufo_type: ufo_point

A multi-point feature in UFO turns into an aggregate point feature in FME. In this case, the feature will have the attribute ufo_pt_origins{<number>} for each point with the <number> being the coordinate index.

The value of this attribute is a comma-separated value list of point origin numbers with the first one being the point origin number for the first point, and the second one being the point origin number of the second point, and so on.

Attribute Name	Contents
ufo_pt_origins	This is the point origin number that refers to the meta feature ufo_meta_pt_origin’s ufo_group_id. Range: 32 bit integer Default: 0

ufo_type: ufo_line

A multi-line feature in UFO turns into an aggregate line feature in FME. In this case, the feature will have the attribute ufo_pt_origins{<number>} for each line with the <number> being the line index. The value of this attribute is a comma separated value of point origin numbers with the first one being the point origin number for the first point and the second one being the point origin number of the second point. Each comma-separated value list contains the point origin number for a line.

Attribute Name	Contents
ufo_pt_origins	This a comma-separated string that holds the list of ufo_pt_origins as describe for Points. If all points of the line has the same value for ufo_pt_origins then this string will only hold that single value. Range: 32 bit integer Default: 0

ufo_type: ufo_polygon

A polygon with more than one line is turned into a donut feature in FME. There is also a multi-polygon feature in UFO that turns into an aggregate polygon feature. In both cases, the feature will have the attribute ufo_pt_origins{<number>} for each polygon, with <number> being the polygon index. The order of the polygons are important.

The value of ufo_pt_origins{<number>} is a comma separated value of point origin numbers with the first one being the point origin number for the first point and the second one being the point origin number of the second point. Each comma-separated value list contains the point origin number for a polygon.

Attribute Name	Contents
ufo_pt_origins	This a comma-separated string that holds the list of ufo_pt_origins as describe for Points. If all points of the polygon has the same value for ufo_pt_origins then this string will only hold that single value. Range: 32 bit integer Default: 0

ufo_type: ufo_text

Text features are not native UFO features. They are created during translation from UFO to other formats, in order to convert the text information which can be part of the UFO feature label descriptions. (Here, we call this UFO feature the original feature.) The text feature is a clone of the original feature with the addition of the attributes ufo_text_size,ufo_text_string and ufo_orientation which are listed in the label description part of the Feature Representation Section, but do no contain the ufo_label{<number>} prefix. The coordinates for the text features are the first set of coordinates of the original feature if it is not available through the original feature's label description.

ufo_type: ufo_none

Note: Meta features must be created in the workspace in the exact order as they are listed here. Otherwise, the translation will return an error. In addition, all regular features must be created before the meta features in order for the UFO writer to function correctly.

Header Feature

The feature type of this feature is ufo_meta_header. The supported attributes are:

Attribute Name	Contents
ufo_coord_sys	A text string which describes the coordinate system used. Range: Text string with max length of 25 Default:ufo_coord_sys

Origin and Definitions of Precision for Points Feature

The feature type of this feature is ufo_meta_pt_origin. The supported attributes are:

Attribute Name	Contents
ufo_group_id	A unique number for KMS which expresses a number for the group. Range: Integer Default: 0
ufo_attr{<number>}	Text strings which contain information belonging to the group. <number> is a positive integer which expresses the line number of the text strings. Range: Consecutive integer starting from 0 Default: 0

Label Types Feature

The feature type of this feature is ufo_meta_label. The supported attributes are exactly the same as those supported by the Origin and Definitions of Precision for Points feature.

Object Reference Types

This is the Object Reference Types feature of the UFO file. The feature type of this feature is ufo_meta_ref. The supported attributes are exactly the same as those supported by the Origin and Definitions of Precision for Points feature.

Origin for Objects Feature

The feature type of this feature is ufo_meta_obj_origin. The supported attributes are exactly the same as those supported by the Origin and Definitions of Precision for Points feature.
