<div class="gmail_quote">Hi all,<br>
<br>
I try to use gdal and otb (<a href="http://smsc.cnes.fr/PLEIADES/lien3_vm.htm" target="_blank">http://smsc.cnes.fr/PLEIADES/lien3_vm.htm</a>)<br>
with pds file.<br>
I try to get value associated to a key (meta-data).<br>
for an exemple the file : Index of /gdal/data/mc02.img contain :<br>
SPACECRAFT_NAME = "MARS GLOBAL SURVEYOR"<br>
INSTRUMENT_NAME = "MARS ORBITER CAMERA"<br>
INSTRUMENT_ID = "MOC-WA"<br>
TARGET_NAME = "MARS"<br>
FILTER_NAME = "RED"<br>
<br>
I would like to access to the key/value FILTER_NAME. But the function<br>
GetMetadata return nothing !<br>
I look in the source code (file pdsdataset.cpp) and the interresting<br>
method is "GetKeyword()" but it is a private method.<br>
<br>
Is someone have an idea how to get all meta data or specific meta-<br>
data ?<br>
<br>
I think is it impossible in fact.. but perhaps is it possible if i add new functionnality<br>
in the pds driver....<br><br>
<br>
regards.<br>
