Conformance statement
20.3.2.1
The NSG must include a conformance statement associated with the content and accuracy of each constituent LSG. This is made available to all NSG Users and provided to each DCA Participating Authority to assist with the continual maintenance and consistency requirements outlined in this Reference Manual. One part of the conformance statement is the measure of the completeness of NSG data as compared to another nationally recognised dataset. Currently, a regular matching process is in place to compare the NSG to address data present in GeoPlace.
