Hey all,
I'm working on an app that needs to pass HDF4 files (MODIS tiles) around as
byte arrays, and then open them up using gdal#Open, from java. Open works
great when I pass in the filepath, so I know that my gdal setup is solid.
The problem is, when I turn the HDF4 file into a byte array and try to use
gdal.FileFromMemBuffer("/vsimem/test.hdf", bytearray);
DataSet data = gdal.Open("/vsimem/test.hdf");
I get an error that reads: "`/vsimem/test.hdf' not recognised as a supported
file format."
I tried something similar, by converting
<VRTDataset rasterXSize=\"1\" rasterYSize=\"1\">
<GeoTransform>100,1,0,100,0,-1</GeoTransform>
<VRTRasterBand dataType=\"Byte\" band=\"1\">
</VRTRasterBand>
</VRTDataset>
to a byte array and reading it in, and that worked great.
Any ideas on how to deal with this issue? I'll note that open SEES the file
in the /vsimem/ directory, it just doesn't recognize it as a valid file. Is
this an issue with HDF4 files, or with large binary sequences? Any ideas on
how to get around this?
Thanks, all,
Sam
