get_nodata_value

get_nodata_value(dtype) → int

Get default nodata value:

if dtype == np.uint8:
    nodata = UINT8_NODATA
elif dtype == np.int8:
    nodata = INT8_NODATA
elif dtype in [np.uint16, np.uint32, np.int32, np.int64, np.uint64, int]:
    nodata = UINT16_NODATA
elif dtype in [np.int16, np.float32, np.float64, float]:
    nodata = FLOAT_NODATA

Parameters:

dtype – Dtype for the wanted nodata. Best if numpy’s dtype.

Returns:

Nodata value

Return type:

int
