Hi,<br>
<br>
I'm having troubles reading a SeaWifs L2 hdf file due to a bug in
the hdf driver. The problem here is that not all Subdatasets are
read. <br>
Below is the list givem by gdalinfo, which lacks 2 subdatasets: the<br>
cntl_pt_cols & cntl_pt_rows<br>
To prove I attach a little screencapture of "HDF Explorer". <br>
<br>
Now I have two questions. <br>
<br>
1- The hdf file in question is relatively small (1.2 Mb). Can I
attach it to a ticket? <br>
<br>
2- If I build GDAL with netCDF4, can I force the reading of this
file with the netCDF driver? And if yes, how?<br>
<br>
Thanks<br>
<br>
Joaquim<br>
