all LAStools read/write NASA ATM QFIT format (*.qi files)

[Martin Isenburg]

Hello,

as of today all LAStools can read and write NASA ATM QFIT format. This
format is used by Operation IceBridge aircraft survey campaigns of
Arctic and Antarctic sea ice, and Greenland, Antarctic Peninsula, and
West Antarctic region ice surface.

In the GUI you can browse for *.qi files by checking the corresponding
button. In the command-line you can simply specify the file names with
a *.qi ending for input or output. These QFIT files are always in a
long/lat/elevation meter representation and are converted on-the-fly
to a LAS file during read and back to a QFIT file during write. Please
let me know if you encounter bugs or undesired behavior in the input
or the output of QFIT formatted files with LAStools.

Cheers,

Martin @lastools
