                             GeoidG2012B

Geoid height interpolator for GEOID12B Model grids CONUS, Alaska, Hawaii, Guam and Northern Mariana Islands, Puerto Rico and U.S. Virgin Islands and American Samoa based on `SciPy` RectBivariateSpline or interp2d interpolation.

Use any of the binary `le` (little endian) or `be` (big endian) `g2012b*.bin` grid files.

Method Details

### __init__(self, g2012b_bin, crop=None, datum=None, kind=3, name=`'````'`, smooth=0) (Constructor) |
New GeoidG2012B interpolator. Parameters: `g2012b_bin` - A `GEOID12B` grid file name (`.bin`). `crop` - Optional crop box, not supported (`None`). `datum` - Optional grid datum (`Datum`), default `WGS84`. `kind` - `scipy.interpolate` order (`int`), use 1..5 for RectBivariateSpline, -2 for interp2d linear, -3 for `interp2d cubic` or -5 for `interp2d quintic`. `name` - Optional geoid name (`str`). `smooth` - Smoothing factor for RectBivariateSpline only (`int`). Raises: `GeoidError` - G2012B grid file g2012b_bin issue, non-`None` crop or invalid kind or smooth. `ImportError` - Package `numpy` or `scipy` not found or not installed. `SciPyError` - A `RectBivariateSpline` or `inter2d` issue. `SciPyWarning` - A `RectBivariateSpline` or `inter2d` warning as exception. Overrides: object.__init__
