GlPosUncertaintyDataType is used for the unc field.
When used as a uncertainty value the semi-major and semi-minor axes have the same value with a semi-major axis orientation set to 0 (value is irrelevant for this case). The altitude uncertainty is independent of the horizontal, elliptical uncertainty. It should be set to -1 if there is no altitude information.
