Data from The National Map is free and in the public domain. We use "Cart" terminology only as a tracking mechanism to maintain download statistics.
USGS has implemented delivery of staged data from The National Map that no longer requires custom clipping. Staged data has already been pre-packaged in tiles so users can download as much data as they want.
USGS has developed a ScienceBase Product Index API that will support calling our catalog of over two million staged data files.
Digital elevation models (DEMs) are staged at resolutions of 2 arc-second in Alaska only (about 60 meters north-south, and varies from 20-35 meters east-west), 1 arc-second (about 30 meters), and 1/3 arc-second (about 10 meters), and are avai
Where can I find conversion scripts to convert downloaded raster data formats, such as for 3DEP, HRO, and NLCD products?
To help in the transition of raster data to different file formats, a set of scripts is available for download at http://viewer.nationalmap.gov/tools/rasterconversion/.
An error may sometimes occur which times out the web browser after clicking on a download link. If you try refreshing, it may open the archive (.zip) file.
The direct FTP link to staged products is: ftp://rockyftp.cr.usgs.gov/vdelivery/Datasets/Staged/.
We have found that if using the Mozilla Thunderbird e-mail client, then download links through a ftp protocol may return empty files.
The "Error: Inventory request failure" message occurs if our ScienceBase catalog database is not responding to download requests.
