#FORMAT POLAR_VECTOR (Polar Vector format)

...

1. Use the functions provided, e.g.

   Code Block
   language powershell
   lats = latitudes(gpt) vals = values(gpt) rh = values(gpt, 'rh') # assuming NCOLS format with a value column of name 'rh'

   
   

2. Use column indexing, e.g.

   Code Block
   language powershell
   lats = gpt['latitude'] vals = gpt['value'] rh = gpt['rh'] # assuming NCOLS format with a value column of name 'rh'

   
   

To assign values to a column, again there are 2 methods, but they have different behaviours:

  geo_clean = remove_missing_values (geo_source) 

Missing coordinates in geopoints

It is possible (since Metview 5.7.0) to include missing values in the latitude or longitude columns (or both). A point with either coordinate missing will be excluded from any operation that requires location information.
