RE: [gdal-dev] NITF Header data
I would think it makes sense to return these two fields as metadata, specifically IGEOLO, since IGEOLO might not be returned as a geotransform (such as in the case when BlockA or other higher precision georeferencing is available). -- Dan Greve Date: Tue, 16 Dec 2008 12:01:05 -0500 From: warmer...@pobox.com To: cjans...@iavo-rs.com Subject: Re: [gdal-dev] NITF Header data CC: gdal-dev@lists.osgeo.org Christiaan Janssen wrote: Does anyone know if it is possible to access any more of the NITF header data than what is currently listed in the GDAL dataset metadata?

[gdal-dev] NITF Header data
Does anyone know if it is possible to access any more of the NITF header data than what is currently listed in the GDAL dataset metadata? There are a number of fields that I have noticed missing, namely ICORDS IGEOLO that I could really use. I realize that these are image subheader components but it would seem to make sense that a GDAL dataset represents a single NITF subimage and that it would contain the subimage specific metadata. Any help is greatly appreciated, thanks. Christiaan___ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
