First, Welcome to the Forum.
This as been a problem for a long time and no doubt will always be a problem. It's a massive project for any company to get all 4 millions of roads in just the US located correctly, but then you throw in trying to make sure the block numbers of all these streets are correct.
DeLorme does it's best to find accurate sources for this information, and sometimes the other companies find it first. But, as users we can all help DeLorme correct their database via NetLink.
To me, given the number of miles of roads, railroads, power lines, rivers, lakes, streams, etc, etc, etc. It amazes me that any of this information is accurate, especially once you throw in Canada and Mexico!
