> Ikonos Data Converter
> This program converts ikonos 16-bit geotiff images to baseline tiff or tga
> files. The motivation was to provide a mechanism for people who don't own
> expensive image viewer to look at images with an inexpensive program link
> GIMP or Paint Shop Pro. Most programs only recognize the TIFF specified 4
> 8 bit greyscale images. The Space Imaging Geotiff format violates this by
> putting it's 11 bit data into a 16 bit field. "i2t" chops off the least
> significant 3 bits for each pixel.
