Subject [jira] [Commented] (CLIMATE-914) Update dataset_processor.spatial_regrid module
Date Thu, 11 May 2017 05:24:04 GMT


ASF GitHub Bot commented on CLIMATE-914:

Github user agoodm commented on the issue:
    No worries, I definitely agree that simply getting the correct result is more important.
I just think it should be looked into in the future, especially if the slowdown proves to
be significant for the longer examples.
    For now though:  :+1:

> OCW's spatial regridding has used scipy.ndimage.map_coordinates. For some unknown reasons,
the map_coordinates function outputs -9999. as a missing value without a mask. We will replace
map_coordinates with scipy.interpolate.griddata that is widely used in the climate science
