Florida’s roads & cities are fairly well mapped, but the conservation lands, trails, forests, grasslands, scrubs, sandhills, & wetlands are generally sparse in OSM. From 1990-2008, Florida had one of the best land protection programs in the state & has protected ~2.5m ac, most publicly-accessible properties of high recreational value.
