The National Map Small Scale

Small-Scale Home


This is a color image of The National Map small-scale map layer Hydrographic Geodatabase of the United States at One Million-Scale showing a portion of the networked hydrography of the United States as of 2014. This map layer contains coastlines, streams, waterbodies and wetlands, and streamflow gaging stations in file geodatabase format. The streams are incorporated into a geometric network. In addition to a national dataset, there are four regional file geodatabases covering the conterminous United States, Alaska, Hawaii, and Puerto Rico and the U.S. Virgin Islands.

This is a color images of The National Map small-scale map layer showing the elevation of the Conterminous United States at 100 Meter Resolution at a ground resolution of 100 meters. This map layer is comprised of four separate data files for the conterminous United States, Alaska, Hawaii, and Puerto Rico and the U.S. Virgin Islands.

The National Map Small-Scale Collection


The 1997-2014 Edition of the National Atlas of the United States was retired in September 2014. However, The National Map (TNM) recognizes the importance of continuing to make a collection of the small-scale datasets, originally developed for the National Atlas, available to users.

Small-scale maps have an advantage over large-scale maps when there is a need to show a large area in a single view. This makes small-scale maps an ideal solution for scientists, decision-makers, and planners needing to provide a geographical context for the research projects. Generally, certain geographical and feature details found in large-scale maps are limited or omitted in small-scale maps. The choice of small-scale maps always comes down to the intended use of the final map.

The National Geospatial Program (NGP) has evaluated the collection of 197 small-scale datasets that were originally part of the National Atlas to identify a subset of data that is particularly relevant to small scale topographic mapping. This subset of data will continue to be available for download from TNM Downloader, and in addition, NGP is assessing a plan to begin regular maintenance of this subset of small-scale data.

The full collection of 197 small-scale datasets, as well as small scale maps and services will continue to be freely available through 2019 at the following pages, and then will be retired permanently.
