Abstract
This is an index of all the National Elevation Dataset (NED) data tiles available at 1/3 arc-second resolution (approximately 10m pixels). All elevation values are in meters and, over the continental United States, are referenced to the North American Vertical Datum of 1988 (NAVD 88). The vertical reference will vary in other areas. Download links are provided for each 1x1-degree tile.
