The numbers given on the census are enumerator references, and so dont usually correspond to any street number or official addresses. The numbers were simply the order the enumerator visited each property to collect the census forms, the sequence is often different between the 1901 and 1911 census.
The one exception to this is that some of the references correspond to building numbers for some streets in cities and larger towns, particularly on the 1911 census forms (rural areas do not use street numbers).
I dont believe the enumerators created any maps showing the sequence they used.
For many areas you can establish a more detailed location for a property using the Cancelled Land Books, aka Revision Books. These are a continuation from Griffith's Valuation and in a similar format, and keep the same plot numbers forward up to the 1900s. The books are held by the Valuation Office in Dublin city, they also have later maps, similar to those used for the original Valuation showing where each property was located. These records are not currently available online.
