Autodesk MapGuide SDL Feature Representation
In addition to the generic FME feature attributes that FME Workbench adds to all features (see About Feature Attributes), special FME feature attributes direct the SDL writer as it renders the feature into the image.
The most important of these is the sdl_type attribute, which controls the overall interpretation of the feature.
The correct values for sdl_type are sdl_line, sdl_point, and sdl_polygon.
The attributes common to each are listed in the following table:
Attribute Name |
Contents |
sdl_url |
Specifies a URL for the line, polygon or point. Required: No Default: Empty string |
sdl_name |
Specifies an internal name for the line, polygon or point. Required: No Defaults:
|
sdl_id |
Specifies an ID for the line, polygon or point. Required: No Defaults:
|
The parameters specified for each of these values are described below.
Lines
sdl_type: sdl_line
The SDL writer outputs a line object containing the points as specified in the input file. Also, the SDL writer outputs a URL, a name, and an ID number associated with the line object as attributes.
Points
sdl_type: sdl_point
The SDL writer will output a point object containing the points as specified in the input file. Also, the SDL writer will output a URL, a name, and an ID number associated with the point object as attributes.
Polygons
sdl_type: sdl_polygon
The SDL writer outputs a polygon object containing the points as specified in the input file. Also, the SDL writer outputs a URL, a name, and an ID number associated with the polygon object as attributes.
