<p class="MsoNormal">Hi there,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have some trouble reading from some particular MODIS files giving me the following error message:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">ERROR 1: GDreadfield() failed for block.<o:p></o:p></p>
<p class="MsoNormal">ERROR 1: HDF4_EOS:EOS_GRID:"/mnt/MODIS/MOD10/2014/MOD10A1.A2014139.h18v04.005.2014141065636.hdf":MOD_Grid_Snow_500m:Snow_Cover_Daily_Tile, band 1: IReadBlock failed at X offset 0, Y offset 0<o:p></o:p></p>
<p class="MsoNormal">ERROR 1: GetBlockRef failed at X block offset 0, Y block offset 0<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The reading in my case only fails for MOD10 products, MOD09 products work fine.
<o:p></o:p></p>
<p class="MsoNormal">This error occurs both when using gdal distributed tools like gdal_translate or when writing my own code reading a rasterband via the RasterIO method.<o:p></o:p></p>
<p class="MsoNormal">The general dataset access works fine, for extracting metadata and retrieving geocoding etc.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I found that a similar issue was reported back in 2009 but I couldn’t find any solution that works for me.<o:p></o:p></p>
<p class="MsoNormal">I have, as suggested in the old threads, compiled GDAL from scratch including many of the external libraries.<o:p></o:p></p>
<p class="MsoNormal">I have used the following libraries and compiled all of them on my CENTOS 7 64bit installation using configure and gmake:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">szip-2.1.tar.gz<o:p></o:p></p>
<p class="MsoNormal">zlib-1.2.8.tar.gz<o:p></o:p></p>
<p class="MsoNormal">tiff-4.0.4.tar.gz<o:p></o:p></p>

<p class="MsoNormal">gdal-2.0.0.tar.gz<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">szip -> ./configure --prefix=/usr/local<o:p></o:p></p>
<p class="MsoNormal">zlib -> ./configure<o:p></o:p></p>
<p class="MsoNormal">tiff -> ./configure<o:p></o:p></p>
<p class="MsoNormal">jpeg -> ./configure<o:p></o:p></p>
<p class="MsoNormal">proj4 -> ./configure<o:p></o:p></p>
<p class="MsoNormal">hdf4 -> ./configure --prefix=/usr/local --with-szlib=/usr/local/lib--with-jpeg=/usr/local/lib --enable-shared=yes --disable-fortran --disable-netcdf<o:p></o:p></p>
<p class="MsoNormal">hdf5 -> ./configure --prefix=/usr/local<o:p></o:p></p>
<p class="MsoNormal">netcdf -> ./configure<o:p></o:p></p>
<p class="MsoNormal">gdal -> ./configure<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">For each library in the order presented here I then executed gmake install. This finished without error messages. When looking in the summary of the gdal build I can see that all libraries are found correctly.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I ran a test on my windows x64 machine, where I also have compiled gdal2.0.0 x64 . There I can read the raster band without problem when running e.g.:<o:p></o:p></p>
<p class="MsoNormal">gdal_translate -of GTiFF HDF4_EOS:EOS_GRID:"M:\MOD10\2014\MOD10A1.A2014001.h18v04.005.2014003062628.hdf":MOD_Grid_Snow_500m:Snow_Cover_Daily_Tile output=test.tif
<o:p></o:p></p>
<p class="MsoNormal">The same command however fails on my linux machine. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Any help in this matter would be greatly appreciated.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks and kind regards,<o:p></o:p></p>
