Reader Overview

WhiteStar datasets store entities as a header (type “B” record) followed by zero or more coordinates (type “C” records) and then by zero or more labels (type “D” records). The WhiteStar reader emits a single feature representing all of the coordinate information for an entity, as well as a feature for each label record in the entity.

Note: If an entity contains multiple line segments or polygons, a mapping file generated by FME to read WhiteStar data will emit a feature for each line segment or polygon in the entity, rather than a single feature with all lines and/or polygons).

Any coordinates to be drawn with the pen in the “up” position are discarded by the WhiteStar reader. The reader interprets the lifting of the pen only as a means to end a polyline or polygon.
