I work in local government and create lots of new features using the OS Master Map (OSMMAP) layer by either tracing or copying and merging; so my new data is derived from OSMMAP but isn't an exact copy of it. A lot of this data has to be republished once ever year or two and when I come back to my layer I find that all the polygons have slipped a little in relation to the OSMMAP layer; I suspect this is because OSMMAP is being updated in the background and shifting slightly, and I would like to know if there was a way to anchor my newly created polygons so I they are properly located on the new version of OSMMAP when I next publish my data?
As I have to edit some of the existing polygons in my layers I manually move the polygon to line it up again and usually end up doing this for my full dataset. As some of my datasets are getting rather large now I think it's about time I learnt to automate this, if possible?
I'm using ArcDesktop /ArcMap 10.5.1 and create my polygons as feature classes in file geodatabases.
