Testimony to Congress on December 5, 1884
“A Government cannot do any scientific work of more value to the people at large, than by causing the construction of proper topographic maps of the country”

Once-over mapping was an immense feat
The only national synthesis of geography that is
Comprehensive
Transjurisdictional
Border to border and coast to coast
Cost of replication today would be $2 to $3 billion

Maps are increasingly outdated
Limited resources restrict maintenance
Maps and digital data do not correspond
Duplication of effort emphasizes the need to share
National priorities demand current information

The National Map must be immediately available to plan for, respond to, and recover from natural and human-induced disasters
The Nation’s urban areas are home to more than 180 million people and much of our critical infrastructure

A seamless, continuously maintained, nationally consistent set of base geographic data – THE NATIONAL MAP
Maintained through partnerships
A national foundation for science, land and resource management, recreation, policy making, and homeland security
Available over the Web and the source for revised topographic maps
The National MapThe National Map – Past and Present – Past and Present

The National MapThe National Map depends on partnerships depends on partnerships
The USGS role emphasizes collaboration to create and maintain data, tools, and applications
Partners include Federal agencies; State, tribal, regional, and local governments; private industry; universities and libraries; and the public
Partner roles include identifying needs for base geographic data, sharing and maintaining data, ensuring data access, developing tools and standards, research, and applications

Road Map to the FutureRoad Map to the Future
Initiated for defense purposes – movement of troops and materielRequired use of nationally-consistent standards – signage, road grades, on and off rampsConstructed using Federal and State matching fundsBuilt largely by private contractorsResulted in greatly improved interstate commerce and mobility
