Field Detail

ALLOW_FCG_PROPERTIES

public static final boolean ALLOW_FCG_PROPERTIES

If set true, the "properties" member is permitted on FeatureCollection and Geometry objects, in contravention of Section 7.1 of the GeoJSON spec RFC7946. Currently, the TFCat does allow properties here, so this value is set true.
