I might be wrong, but from reading the metadata of the derived dataset, I think the base dataset basically only has parcels, but not forestry specific information attached to that, while the derived dataset uses the parcels and then adds forestry specific information to them.

Brendan, the original (i.e. pre-derived) VMPROP.PARCEL_CROWN_APPROVED file is also available at: http://services.land.vic.gov.au/SpatialDatamart/dataSearchViewMetadata.html?anzlicId=ANZVI0803004688 <http://services.land.vic.gov.au/SpatialDatamart/dataSearchViewMetadata.html?anzlicId=ANZVI0803004688&extractionProviderId=1> &extractionProviderId=1 Hence, if there were to be any issues in using the derived file, the original file could still be used (if permission has been granted). I imagine that it is a much bigger file and contain lots of other info. The SF boundary data should be the same in both presumably.

Unfortunately I'm also unclear as to whether we have permission to use these. If a CC-BY-4.0 dataset is "derived" from a base layer, and we have permission for that base layer, is permission inherited? That is assuming the "VMPROP" product listed is "Vicmap Property", of course. Two assumptions made just then. @Andrew Harvey <mailto:andrew.harv...@gmail.com> , or anyone else familiar with our requirements, is it worthwhile revisiting the Vicmap waiver to get clarity on Vicmap derivatives? https://wiki.openstreetmap.org/wiki/File:Vicmap_CCBYPermission_OSM_Final_Jan2018_Ltr.pdf ..Brendan
