The law here is clearly overly vague and needs clarifying, but so too does the source of data on published maps. A map to be shared, particularly for any legal or regulatory purpose, should include a note stating the source(s) of the data depicted. The source could be a surveyor, or it could be Google Maps, or a particular GIS database, or whatever, but provided the data source is clearly stated, then potentially damaging ambiguity is minimized, and a clear paper trail as to accuracy and reliability is established.
