I found this site looking for low bridge clearances, Australia and found data, but one location (Mooroolbark Rd) needs changing from 3.2 metres to 3.4 metres. Original source data was incorrect and now acknowledged by road authority. Can/will this be communicated to the most popular map data sets through this forum?
Also in the underlying map a Manchester Road vector incorrectly turns left into, and continues 40 metres plus up Shadowplay Rd. This is also common across suppliers (Google, Whereis, Tom Tom, Bimp). Is there a central coordinating body to apply the fix? (Town=Mooroolbark, State= Victoria, Country = Australia)
