grdsample (pixel to gridline) returns nans #3090
Labels
bug
Something isn't working
Comments
I also note that the GMT commands returns "1"s for all data values for all three grids. In the pixel grid above, the first two rows have values that are not unity. |
I believe these are caused by grid padding (extra rows/columns at the grid boundary). Currently, there is very little we can do on the PyGMT side. Hopefully, the issue can be addressed after PR #2398. |

Description of the problem
When using the grdsample routine to translate from pixel registration to gridline registration, the output contains nans at the poles. This does not occur when using the GMT command line utilities.
