Re: How to place hdf raster in correct location

Hi etis, It looks like the reason that the .h5 is failing to read in the correct location is that the CRS information is not included in the metadata in a way that QGIS can read it/interpret it. From what I have read, reprojecting an .h5 file in QGIS is tricky. I would recommend using Earthdata sear...

Re: Polar stereographic and EASE-Grid projections

The two grids are based on different map projections. The polar stereographic projection was initially used with ice concentration products developed at the NASA Goddard Space Flight Center (GSFC) and has been retained for historical consistency. It specifies a projection plane tangent to the earth ...

Re: Ice surface temperature

Hi Ippolita, The HDF EOS Tools and Information Center has a webpage with example code for various NSIDC data sets - http://hdfeos.org/zoo/index_openNSIDC_Examples.php#MODIS. This webpage also contains some more generic example code for using HDF in MATLAB - https://www.hdfeos.org/examples/index.php....
