1:1M scale networked hydrography for the Nation (water features and streamgages)
Base maps designed for Streamer emphasize hydrographic features over transportation and political features. These map services are available to the general public for use in web mapping applications requiring small scale hydrographic base maps. The Map Services for Developers site provides information required to add the Streamer map services to your own application.
