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.

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). Point label features are also accommodated to carry annotation. No polygons with holes can be stored directly.

The format can hold linear features, which may be closed into simple polygons. In some circumstances, the coordinates may be in degree, minute, second format. The format does carry coordinate system information and supports several different projections, though normally it carries coordinates in decimal lat/long format. It does not support user-defined attributes. The WhiteStar format is a two dimensional format that employs a major/minor code scheme similar to that used by the USGS DLG format. sells a variety of digital map data in this format, much of it targeted at the oil and gas, pipeline, natural resource, and engineering industries. This format is also known as the Cartographic Data Format (CDF) Version 1.0 used by the GeoGraphix ® Exploration System (GES) mapping package.

The Halliburton GeoGraphix CDF format Reader and Writer modules provide the FME with the ability to read and write WhiteStar files.
