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).<br><br>-- Dan Greve<br><br>> Date: Tue, 16 Dec 2008 12:01:05 -0500<br>> From: warmerdam@pobox.com<br>> To: cjanssen@iavo-rs.com<br>> Subject: Re: [gdal-dev] NITF Header data<br>> CC: gdal-dev@lists.osgeo.org<br>> <br>> Christiaan Janssen wrote:<br>> > Does anyone know if it is possible to access any more of the NITF <br>> > header data than what is currently listed in the GDAL dataset metadata? <br>> > There are a number of fields that I have noticed missing, namely ICORDS <br>> > & IGEOLO that I could really use.
