Unfortunately from the documentation it was not\r\nclear to me how the latitude, longitude values of certain EASE grid resolutions\r\nwere calculated. So I wrote this package to find out.\r\n\r\nSupported EASE Grids\r\n====================\r\n\r\nThere are two versions of EASE grid systems. This package focuses on EASE-Grid\r\n2.0 at the moment. The data we were reading is disseminated on the global\r\nEASE-Grid projection which is why this is the one that is currently supported.\r\n\r\nCalculation of any global EASE2 grid should work. Compability with the tiling\r\nscheme of NASA is tested for the global 36km grid (``EASE2_M36KM``) and the\r\nglobal 25km grid (``EASE2_M25KM``). The tiling of the 25km grid is only the same\r\nas the NASA tiling if the ``map_scale`` parameter is given explicitely. This\r\nwill also be the case for the subgrids of the 36km grid like ``EASE2_M09KM`` and\r\n``EASE2_M03KM``. The ``map_scale`` parameters used by NASA are available from\r\nthe file ``ease2_grid_info.pro`` inside the ``easeconv*.tgz`` file at\r\nftp://sidads.colorado.edu/pub/tools/easegrid/geolocation_tools/\r\n\r\nHow to use\r\n==========\r\n\r\nTo get the coordinates of a EASE2 grid:\r\n\r\n.. code-block:: python\r\n\r\n from ease_grid import EASE2_grid\r\n egrid = EASE2_grid(36000)\r\n assert egrid.shape == (406, 964)\r\n # these two attributes contain the longitude and latitude coordinate dimension\r\n egrid.londim\r\n egrid.latdim\r\n\r\nNote\r\n====\r\n\r\nThis project has been set up using PyScaffold 2.5.6.
