Hi all,
There is a function called NITFReadBLOCKA_GCPs in nitfimage.c that can
read earth coordinates for image corner locations in the NITF image
subheader to provide higher precision. Is there a function that can
write higher precision earth coordinates into the NITF image subheader?
Is there an option in gdal_translate so that the earth coordinates can
be written into the NITF image subheader? Thanks in advance.
Mo,
Currently GDAL does not support creating a BLOCKA segment automatically
from GCPs. If you know exactly what you are doing, you can create BLOCKA
segment but you need to pass the appropriate creation options when creating
the NITF file. There is some documentation of this in:
http://www.gdal.org/frmt_nitf.html
Best regards,
