Resource: identifier

The identifier resource is used to specify station identifiers to the program when a program needs to parse or decode a specific station.  A list of stations can be provided separated by commas. The station identifier resource has the ability to parse for more than a list of stations.  Here is a list of keywords:

• Name=station_name -- This can be used to parse for the station name (column 1) out of the city dabase file.  An example would be "name=cleveland". The names can be abbreviated.  The program uses the first one that matches.
• ST=state -- This uses the name of the state.  If the state is 2 characters, it is the state abbreviation such as "ST=PA".   If it is 5 characters, it is the state and country, such as "ST=MN_US".
• CN=country -- This uses the 2 character name of the country such as "CN=DL" for Germany.
• ID=ident -- This uses the 3 or 4 letter identifier (ICAO).   The "ID=" can be omitted.
• Ra<lat,lon,range -- This uses all stations that are within range km of the specified center point lat,lon.
• P=prior -- This uses all stations that have exactly that priority.
• P<prior -- This uses all stations that have that priority or less.  This is the equivalent of specifying the stat_prior resource.
• P>prior -- This uses all stations that have that priority or greater.
• Lat<latitude -- This uses all stations that have a latitude less than or equal to latitude.
• Lat>latitude -- This uses all stations that have a latitude greater than or equal to latitude.
• Lon<longitude -- This uses all stations that have a longitude less than or equal to longitude.
• Lon>longitude -- This uses all stations that have a longitude greater than or equal to longitude.
• Elev<elevation -- This uses all stations that have an elevation less than or equal to elevation.
• Elev>elevation -- This uses all stations that have an elevation greater than or equal to elevation.
• WMO=wmo -- This uses the station with this WMO number.
• WMO<wmo -- This uses all stations that have an WMO number less than or equal to wmo.
• WMO>wmo -- This uses all stations that have an WMO number greater than or equal to wmo.
