Raw Data Download Help

You can use the Raw Data Download table to quickly determine all the maps offered in the Map Maker and to learn more about them. The 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 raw 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 raw data from the National Atlas. The latest raw data documentation
available from nationalatlas.gov is always accessible from this table.

All of our raw 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 our raw data to speed delivery over the World Wide Web. Simply click on a raw data file name to begin downloading.

We offer far more detailed help for those who wish to download our data.
