Sorry, I was confused and didn't open up all the sub-parts of the page. It says "ANCHOR EPOCH" = "2010.0". So this is exactly the "NAD83(2011) epoch 2010.0" in use for RTK networks (and everything else). Adding anchor epoch is a relatively recent change, in November of 2024. https://epsg.org/closed-change-request/browse/id/2024.065 I guess it's interesting but not important that the dynamic datum this is derived from is (apparently) not in the db. _______________________________________________ PROJ mailing list [email protected] https://lists.osgeo.org/mailman/listinfo/proj
