SUMMARY

A national map as conceptualized by the USGS is justified and timely. Authority for such an enterprise is already delegated, yet the undertaking will require a cultural shift in the way that the USGS approaches its mapping. The future of mapping in the United States depends on forging partnerships among all levels of government and the private sector.
