pygmt.GrdMathCalc

class pygmt.GrdMathCalc(arg_str=None)

Raster calculator for grids (element by element).

Examples

>>> grdcalc = GrdMathCalc()

>>> # Basic square root operation
>>> grid0 = grdcalc.sqrt(
...     ingrid="@earth_relief_01d", outgrid=True, region=[0, 3, 6, 9]
... )

Methods Summary

GrdMathCalc.compute()	Perform the grdmath computation and returns an xarray.DataArray object.
GrdMathCalc.grdmath(operator[, ingrid, ...])	Raster calculator for grids (element-wise operations).
GrdMathCalc.multiply(ingrid[, outgrid])	A * B.
GrdMathCalc.sqrt(ingrid[, outgrid])	sqrt (A).
GrdMathCalc.std(ingrid[, outgrid])	Standard deviation of A.
