This is the same NED data except in Grid float format. These files are twice as big as the BIL format. They will run a bit slower for generating network backgrounds.
Downloading
The files are named by the North West corner having the following syntax:
NXXWYYY.zip where XX = the latiude in degrees and YYY = longitude in degrees
The files are available in two resolutions:
