ADDS Text Data Server - Station Information Examples


 

Station String

stationString
  • station id using the four-letter specification

  • delimited by white spaces and/or commas (,)
stationString=KDEN KSEA, PHNL obtain station information for KDEN, KSEA and PHNL
stationString
    using partial icaoId name
stationString=KSEA KDE obtain stations for KSEA and all icaoIds beginning with KDE (i.e. KDEN, KDEH, KDEW, ...etc.)
stationString
    using partial icaoId name and wildcard (*)
stationString=KSEA KDE* equivalent to above, obtain stations for KSEA and all icaoIds beginning with KDE
stationString
    using '@' and two-letter U.S. state (or two-letter Canadian province) abbreviation to obtain stations for a state
stationString=@WA obtain stations for all icaoIds from Washington state
stationString stationString=@BC obtain stations for all icaoIds from British Columbia, Canada
stationString
    using '~' and two-letter country abbreviation to obtain stations for a country

Lon-Lat Rectangle

Parameter(s) Allowed Values Example(s) Description
minLat, minLon, maxLat, maxLon
  • longitude and latititude in decimal degrees

  • -180<= lon <=180

  • -90<= lat <=90

  • Please refer to : latitude and longitude for a refresher on these ranges.

  • parameters can be listed in any order
minLat=25&minLon=-130& maxLat=65&maxLon=-40 obtain stations collected within a rectangular region (bounding box) defined by the min and max lon and lat

NOTE:

  • The LonLatRect constraint can accomodate situations where the bounding box crosses the International Date Line
  • The LonLatRect constraint does not support bounding boxes that cross the poles.

 

Radial Distance

Parameter(s) Allowed Values Example(s) Description
radialDistance
  • a radius (statute miles) around a point (longitude and latitude in decimal degrees)

  • -180<= lon <=180

  • -90<= lat <=90

  • 0< radius <=500

  • Radius and origin are separated by a semicolon(;)

  • Described area may not cross the international dateline or either pole

  • Please refer to : latitude and longitude for a refresher on these ranges.

radialDistance=20;-104.65,39.83 obtain stations within 20 statute miles of -104.65,39.83 (KDEN)
 

Flight Path

Parameter(s) Allowed Values Example(s) Description
flightPath
  • maximum distance in statute miles

  • two or more way points (indicated by lon, lat)

  • lon, lat are delimited by a comma (,)

  • maximum distance MUST precede the way points

  • maximium distance and way points are delimited by a semicolon( ;)

  • the ordering of waypoints is significant: always start with origin, end with destination

flightPath=57.5; -125.27,49.95; -104.65,39.83 obtain all stations for the flight path from Campbell River, BC to Denver, CO using a 57.5 statute mile maximum distance
flightPath flightPath=57.5; -104.65,39.83; -97.5,27.77; -81.33,28.42; -73.15,44.47 A flight path from Denver,Co to Corpus Cristi, Tx to Orlando, Fl to Burlington, Vt using a 57.5 statute mile maximum distance.
flightPath flightPath=57.5; KDEN; -97.5,27.77; -81.33,28.42; -73.15,44.47 A flight path from Denver,Co to Corpus Cristi, Tx to Orlando, Fl to Burlington, Vt using a 57.5 statute mile maximum distance and the station name for Denver.
NOTE:
Flight path results are sorted by distance along the flight path, from origin to destination.

The flight path constraint cannot accomodate the following situations:
  • flight paths that cross the poles

  • flight paths that cross the International Date Line.

 

Density

Parameter(s) Allowed Values Example(s) Description
minDegreeDistance 0 < any value <=90

The degree distance is the distance (based on longitude and latitude)
between stations. The larger the
value of minDegreeDistance, the less dense the results.
Duplicate stations are filtered and the most recent of duplicate
stations is reported.
flightPath=57.5; KDEN; KMCO& minDegreeDistance=90 obtain all stations for the flight path from Denver, CO to Orlando, FL using a 57.5 statute mile maximum distance and requesting the lowest density of results.
minDegreeDistance 0 < any value <=90

The degree distance is the distance (based on longitude and latitude)
between stations. The larger the
value of minDegreeDistance, the less dense the results.
Duplicate stations are filtered and the most recent of duplicate
stations is reported.
flightPath=57.5; KDEN; KMCO& minDegreeDistance=1 obtain all stations for the flight path from Denver, CO to Orlando, FL using a 57.5 statute mile maximum distance and requesting a high density of results.
 

Field Parameters

Parameter(s) Allowed Values Example(s) Description
fields
  • Constrain the results to contain only the fields of interest.

  • Indicate the fields of interest by a list of space or comma
    (,)
    delimited field names (as indicated in the Station Field Description Table).

  • If no fields are indicated, the default condition is assumed and all available fields in the Station Field Description are returned.

flightPath=57.5; -125.27,49.95; -104.65,39.83 &fields=station_id, elevation_m obtain all stations for the flight path from Campbell River, BC to Denver, CO using a 57.5 statute mile maximum distance. Only the available sky cover, cloud base, elevation and vertical visibility results are returned.
