I was thinking more along the lines of your ‘harvest everything then map’ intent – there are very precise ways to apply that type of mapping (such as outlined by the NSDL at one point) but they require extensive sustained effort; I reckoned you were probably taking more of a ‘does this skilled hack work well enough?’ approach (or what can I offer without getting stuck on the human intensive bits).

Skilled hack, like a butcher. Perhaps I no longer harvest.
