Not directly related to this PR, but running grd2xyz gives me unexpected output:
>>> pygmt.grd2xyz(grid=grid, outcols=2, output_type="numpy")
array([[1536., nan, nan],
[1539., nan, nan],
[1542., nan, nan],
...,
[2793., nan, nan],
[2800., nan, nan],
[2802., nan, nan]])
So it looks like a bug, right?

Yes, this is a PyGMT issue related to how the temp file output is read into a pandas.DataFrame.

Two comments here:
pygmt.grd2xyz(grid=grid, outtput_type="pandas")["elevation"]is more readableShould we limit the use ofoutcolstooutput_type="file"only, otherwise we have to parseoutcolsand process the output columns.
