that should be right, it's the L3m SMI/HDF download, not the BIN/HDF one. > gdal_translate -a_srs "+init=epsg:4326" -a_nodata 65535 > -a_ullr -180 90 180 > -90 -co "COMPRESS=PACKBITS" > HDF4_SDS:UNKNOWN:"A20100252010032.L3m_8D_CHL_chlor_a_9km":0 > prueba.tif > Input file size is 4320, 2160 > 0ERROR 1: SDreaddata() failed for block. > ERROR 1: IReadBlock failed at X offset 0, Y offset 0 > ERROR 1: GetBlockRef failed at X block offset 0, Y block > offset 0 I'm working with this data reasonably often and I've never seen that error, sorry.
