Old .BIL Format - USGS National Elevation Dataset Files

Q: How are the National Elevation Dataset (NED) files from the USGS available from SoftWright?

A: TAP 4.5 and later, using TopoScript data access, can read the NED format files.

The graphic below shows the location of the "off the shelf" NED files for the continental United States, Alaska, Hawaii, and Puerto Rico. Custom files can also be prepared. A listing is also available to show the exact limits for each file.
