USGS adds enhanced tools to National Map program

US: To make the GIS data easily accessible, usable, and downloadable, the U.S. Geological Survey has made some improvements to the National Map program. The downloading capabilities will now be available through the TNM Download Client, replacing the legacy TNM Viewer and allowing users to download larger quantities of data more quickly.

To access it, users will have to filter the data by product and file format, and search over an area of interest. New product-specific workflows allow users to select particular hydrologic unit and receive more appropriate results.  Data can be downloaded directly or placed in a “cart” for download later. An application programming interface is also now available that developers can use for their own applications.

Some other enhancements that was recently done by USGS on the National Map was a Download Manager that helps users download multiple products, making it easier to export search results into a .CSV file; a contours map service for large-scale (1:24K) maps; vector web services that allow users to change the color and line weight of vectors to customize mapping without having to download the dataset; a new launch page for navigating data resources.

With these releases, the USGS will be retiring the Geodatabase 9.3.1 format in mid-February and the removing of the download function in the legacy viewer, directing users to the new download client. The National Map Viewer will remain online for web-based analysis.
