Thank you for the quick, helpful response. Sounds like I need to dig into the
NITF spec to determine how to best use the available precision. Thanks again.

NITF base georeferencing using the IGEOLO field sucks because there's
not enough decimal digits to compute the full accuracy of a
geotransform, and thus when GDAL tries to reconstruct the geotransform
from the 4 corners (that's how georeferencing is stored), the threshold

I am doing a real-time SAR spot simulation where the SAR orbits a target point
and saves a series of the georeferenced spot image files. My initial
implementation generated non-GDAL GeoTIFF or JPEG files. I use a least-squares
algorithm to develop the 6 affine geotransform values. This all wo
