This is good but seems like an awful lot of double, triple, quadruple+ handling as groups/custodians write down details to post elsewhere which are then copied back to providers, then eventually corrected.
Has there been any thought given to an OpenStreetMap-like system where the geometry and attributes are submitted directly, or even *shock, horror* validating basemap features against OSM itself?
Yes I realise that an open crowdsourced system is not the same as authoritative data, but could be used to test veracity/currency to give a confidence rating.
