   > What is this language?
   
   > The axis order of the coordinates in WKB stored in a GeoParquet follows 
the de facto standard for axis order in WKB and is therefore always (x, y) 
where x is easting or longitude and y is northing or latitude. This ordering 
explicitly overrides the axis order as specified in the CRS.
