I'm not sure what you mean by getting the metadata information from the source dataset to the destination dataset. If you are referring to the metadata that ArcGIS maintains, such as all of the FGDC metadata it keeps in an XML file, I suspect that GDAL does not recognize that metadata. That metadata is a feature of ArcGIS. You might be able to use the "Metadata Importer" geoprocessing tool from ArcGIS 9.3 to copy the metadata from one raster to another, but I don't think GDAL has any support for it.
I followed the discussion about not being able to read the IMG files but I don't know an answer to that. Others on the list have more expertise in that than I do. I looked at the IMG files you mentioned. The one output by GDAL looks fine to me. It appeared that the only differences were the number of spaces separating the values and the number of digits of precision in the floating point numbers. Are these differences important to you? You do have some control over the format of the floating point numbers. See the discussion of the DECIMAL_PRECISION option in http://www.gdal.org/frmt_various.html Best, Jason -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of mail2vajram Sent: Wednesday, May 19, 2010 12:17 AM To: [email protected] Subject: [gdal-dev] Re: Hoe to convert ERDAS imagine(.img) files to ARC info ASCII files viceversa Hai, Jason thanks for your reply....
