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 topic.
Each feature returned by the GenaMap reader has its feature type set to the name of the input map. All GenaMap FME features contain the genamap_type attribute that identifies the geometric type.
Attribute Name | Contents |
---|---|
genamap_type |
The type of geometric entity stored within the feature. The valid values are listed below: genamap_point genamap_line genamap_area genamap_text |
General Attributes
All GenaMap FME features contain the following attribute:
Attribute Name | Contents |
---|---|
genamap_tag |
The primary GenaMap attribute. |
Type 4 and Type 5 maps carry the additional attribute:
Attribute Name | Contents |
---|---|
genamap_symbology_id |
The GenaMap symbolization pointer value. |
Points
genamap_type: genamap_point
GenaMap point features specify point features defined by a single x,y or x,y,z coordinate.
Lines
genamap_type: genamap_line
GenaMap line features specify linear features defined by a sequence of x,y or x,y,z coordinates.
Polygons
genamap_type: genamap_polygon
GenaMap polygon features specify area (polygonal) features. The polygon may contain holes.
Text
genamap_type: genamap_text
The GenaMap text features are extracted from GenaMap Type 10 maps. Each text feature has a single x and y coordinate. The text coordinate point is located at the lower left of the text string. The original GenaMap origin point and justification are also stored in the text features as the attributes genamap_original_x, genamap_original_y, and genamap_original_justification. Text features have the following special attributes associated with them.
Attribute Name | Contents |
---|---|
genamap_text_string |
The text string. Range: Any character string |
genamap_rotation |
The rotation of the text measured in degrees counterclockwise from horizontal. Range: 0...360 |
genamap_width |
The width of each text in ground units. Range: Any real number >= 0 |
genamap_height |
The height of each text in ground units. Range: Any real number >= 0 |
genamap_original_ justification |
The original GenaMap alignment of the text based on the original GenaMap text origin point. Range: upper_left | upper_center | upper_right | center_left | center_middle | center_right | lower_left | lower_center | lower_right |
genamap_original_x |
The original GenaMap text origin point x coordinate. |
genamap_original_y |
The original GenaMap text origin point y coordinate. |
genamap_char_ |
The rotation of each character in the text string measured in degrees counterclockwise from the horizontal. Range: 0...360 |
genamap_slant |
The slant for each character in the text string. A negative angle gives a clockwise slant; a positive angle gives a counterclockwise slant. Range: -90...90 |
genamap_font |
The GenaMap lettering style. Range: Any valid GenaMap system font. integer >= 0 |
genamap_color |
The GenaMap color of the text. Range: GenaMap color index. integer >= 0 |
