Export restriction on high-resolution geospatial data; attributes for listed sensitive installations restricted, owner-published exceptions apply. Prohibits export of maps and geospatial data that are more precise than the DST-prescribed spatial, gravity and bathymetric accuracy thresholds, and restricts export of specified sensitive attributes for an enumerated list of security, defence, nuclear, aviation, naval and strategic installations. These features must not be labelled or have attributes attached in vector or geo-tagged raster form. Restrictions may be relaxed only where the facility owner has publicly authorised disclosure.
