Prints values from all\n                   dimensions of the grid.\n\n\nGet information about a 3D grid::\n\n  $ kmsgrid info nkgrf03vel.01\n        filename:  nkgrf03vel.01\n      dimensions:  3\n          latmin:  53.0\n          latmax:  73.0\n          lonmin:  3.0\n          lonmax:  40.0\n     data[0].min:  -0.96\n     data[0].max:  1.75\n    data[0].mean:  0.204704\n     data[1].min:  -1.65\n     data[1].max:  0.86\n    data[1].mean:  -0.194318\n     data[2].min:  -0.72\n     data[2].max:  9.97\n    data[2].mean:  2.34521\n            dlat:  0.0833333333333\n            dlon:  0.166666666667\n            nlat:  241\n            nlon:  223\n           datum:  ITRF19yy/20yy\n            mode:  KMSGrid\n       tabletype:  3D\n\nValues in a single grid cell at index 55,12::\n\n    $ kmsgrid info Geoids2013\\nkgrf03vel.01 --point 55 12\n    0.649999976158 -0.200000002980 -0.720000028610\n\n\nTranslate\n...............................................................................\n\nThe ``translate`` sub-command work similar to ``gdal_translate`` in that it\ntranslates from one format to another. In fact, behind the scenes, it uses GDAL\nto convert KMS grids to more common formats. Only a small subset of the\nGDAL formats available can be used with ``kmsgrid``.\n\n::\n\n    $ kmsgrid translate --help\n    usage: kmsgrid translate [-h] [--driver DRIVER]\n                             [--creation_options CREATION_OPTIONS]\n                             grid out dimensions [dimensions ...]\n\n    positional arguments:\n      grid                  Binary grid file.\n      out                   Name of output grid file\n      dimensions            List of dimensions in output grid, e.g. \"1 2\"\n\n    optional arguments:\n      -h, --help            show this help message and exit\n      --driver DRIVER, -d DRIVER\n                            Output format. Currently supports: GTiff, GTX, NTv2\n      --creation_options CREATION_OPTIONS, -co CREATION_OPTIONS\n                            Additional GDAL creation options. Must be formatted\n                            as \"PARAM1=foo PARAM2=bar\".\n\nTranslate the DVR90 geoid grid to GTX format::\n\n    $ kmsgrid translate --driver=GTX dvr90g2013.01 dvr90.gtx 1\n\nTranslate the NKG velocity model to two grids, one for the horizontal part in\nNTv2 format and one for the vertical part in GTX format:\n\n    $ kmsgrid translate --driver=NTv2 nkgrf03vel.01 nkgrf03vel_xy.gsb 1 2\n    $ kmsgrid translate --driver=GTX nkgrf03vel.01 nkgrf03vel_z.gtx 3\n\n\nAPI\n-------------------------------------------------------------------------------\n\nThis is just a simple example of how the API can be used::\n\n    from kmsgrid import KMSGrid\n\n    # print some useful info\n    grid = KMSGrid('dvr90g.2013.01')\n    print('Dimensions of grid: {0}'.format(grid.dims))\n    print('Datum of grid: {0}'.format(grid.datum))\n    print('Bounding boix of grid: [{0}, {1}, {2}, {3}'.format(\n        grid.lonmix, grid.latmin, grid.lonmax, grid.latmax))\n\n    # convert grid to a TIFF file\n    grid.export(filename='dvr90.tif', dimensions=1)\n\n\nInstalling\n===============================================================================\n\nClone the repository from GitHub and run the following command in the local\nrepository folder:\n\n::\n\n  $ python setup.py install\n\nAlternatively ``kmsgrid`` can be installed from the Python Package Index with\n``pip``::\n\n  pip install kmsgrid\n\n\n",
