Agreed. But, consider also how this may be extended with new data elements in the future. Compare 
$Easting{$Line}{$Station}
vs 
$Data{$Line}{$Station}{Easting}
For example, if you were to add lat/long or one of the misc items to Station, the second structure would more easily accommodate that new data.
