New Framework Map Layers in Work
Skilled cartographers and technicians have been busy compiling new basic
layers of map information for inclusion in the National Atlas of the
United States®. This might not seem newsworthy since our staff has
maintained and revised these foundation map layers for the past eleven
years. We’ve always taken pride in offering an accurate and authoritative
set of information about America’s surface waters, boundaries,
and transportation networks. What is noteworthy is that we have started
fresh using the best available sources to create a new set of these frameworks
at a scale of 1:1,000,000 (where one inch on a map represents approximately
16 miles on the land). Until now, all fundamental map layers had been
produced at 1:2,000,000 - a legacy of The National Atlas of the United
States of America® of 1970 that included a series of basic maps at
this scale.
Moving to a scale of 1:1,000,000 offers important advantages to users
of the National Atlas. The most apparent of these is that our basic maps
will be more detailed. We will be

able to map and include more information about the United States than
we’ve offered in the past. For those interested in our nation’s streams,
lakes, and ponds, we are pleased to announce that our new surface waters
map layer is a generalization of the 1:100,000-scale National
Hydrography Dataset (NHD). We intend to offer a fully networked version
of this map layer that includes flow direction and all other advantages
of the NHD. A third benefit of mapping at 1:1,000,000-scale is that the
National Atlas of the United States® can fully support the creation
of the Global
Map. This is an effort by national mapping organizations around the
world to produce standard maps that cover the globe. Another potential
advantage of mapping at this larger scale relates to the North
American Atlas described earlier. Since we started this work in 2004,
we have made maps and data at a scale of 1:10,000,000. Atlas programs
in Canada and Mexico produce frameworks at 1:1,000,000-scale and we now
have the potential to work with our southern and northern partners to
produce an integrated set of frameworks for the entire continent at this
larger scale.
At present, we are working on tightly integrating these new map layers.
We intend to release them all in 2009. Some provisional map layers are
already available from the Global
Map.
