[gdal-dev] Metadata from GeoTIFF to ENVI

[Nevzat Guler]

Thanks Even.
I changed the line as you suggested but still missing some of the information in the header file. The header I get has the following:

ENVI
description = {
createdFile.hsi}
samples = 7571
lines   = 7411
bands   = 1
header offset = 0
file type = ENVI Standard
data type = 12
interleave = bsq
byte order = 0
band names = {
Band 1}
AREA OR POINT = Point

But, I know there are more info in the metadata including map info, coordinate systems and extents data etc.. 

How do I access to the metadata, meaning, how do I learn what kind of information exists in the papszMetadataSet variable? If I knew that I could try to write the header file myself. I am sorry if this is explained in somewhere but I could not find any example on how to access to metadata.

Best regards ,

Nevzat,

According to http://www.gdal.org/frmt_various.html#ENVI , "all ENVI header fields will be stored in the ENVI metadata domain, and all of these can then be written out to the header file". Which means in your case, you should motify your last line to be :

poDstDS->SetMetadata(papszMetadataSet, "ENVI");
