This is, im told, an engraving of Gibraltar -
I know of no software that can create a vector file like that, however, if you had such a tool path, then (aside from the massive number of machine hours) there is little reason why such a file could not be cut.
But...
That type of relief work may not even be suitable for your application. To get the detail, you either need the job to be massive (ie look at it from a distance, and produce it on a machine larger than anyone has knocking about!), or you would need a very fine cut.
If you have a fine cut, and leave it outside for years and years, corrosion, vandalism, etc.etc. would do for it anyhow.
There is no perfect solution - its a case of deciding which compromises work with your end goal the best.
