You can use the National Atlas Data Download
table to quickly determine all the maps offered in the Map
Maker and to learn more about them. This index is arranged in a
table with five columns.
If you're like most National Atlas users, you'll
only be interested in the first two columns. These include the
map layer names and release dates. To see these, click on any
sign in the table.
You can click on any name in the first column to learn more about
the map layer.
For those mapping professionals who have already invested in their
own desktop mapping or geographic information systems, the other
three columns should be of interest. The third column lists the
year that we most recently revised a map layer's National Atlas
Data Documentation. Click on this date to view documentation
that complies with the existing Federal metadata standard. This
will help you determine whether to download National Atlas Data. The current National Atlas Metadata
available from nationalatlas.gov is always accessible from this
All National Atlas Data are provided at no cost and may be available
in more than one format. If so, each format is listed in the fourth
column and each file's size is shown in the fifth. Please
note we compress National Atlas Data to speed delivery over the World
Wide Web. Simply click on a file name to begin downloading.
We offer far more detailed
help for those who wish to download our data.
