hydromt.gis_utils.meridian_offset#

hydromt.gis_utils.meridian_offset(ds, bbox=None)[source]#

Shift data along the x-axis of global datasets to avoid issues along the 180 meridian.

Without a bbox the data is shifted to span 180W to 180E. With bbox the data is shifted to at least span the bbox west to east, also if the bbox crosses the 180 meridian.

Note that this method is only applicable to data that spans 360 degrees longitude and is set in a global geographic CRS (WGS84).

Parameters:

ds (xarray.Dataset) – input dataset
bbox (tuple of float) – bounding box (west, south, east, north) in degrees

Returns:

ds – dataset with x dim re-arranged if needed

Return type:

xarray.Dataset
