Time Range

Parameter(s)	Allowed Values	Example(s)	Description
startTime, endTime	start and end times in seconds since January 1, 1970 query based on aircraft report obsTime	startTime=1743504916& endTime=1743512116	obtain all aircraft reports collected between the start and end times

Please refer to W3C date/time formats
startTime, endTime	start and end times in ISO8601 date/time format query based on aircraft report obsTime	startTime= 2025-04-01T03:55:16+0700 &endTime= 2025-04-01T05:55:16+0700	obtain all aircraft reports collected between the start and end times in ISO8601 date/time format using local offset: YYYY-MM-DDThh:mm:ss+ hhmm OR YYYY-MM-DDThh:mm:ss- hhmm NOTE: Due to differences in character encodings by various web browsers, the + might get encoded to a whitespace. To avoid this from occurring, use %2B in place of the +. Please refer to W3C date/time formats.
hoursBeforeNow	any positive integer or floating point value n = number of hours before current time query based on aircraft report obsTime	hoursBeforeNow=1	obtain all aircraft reports collected in the last hour

 

Most Recent

Parameter(s)	Allowed Value(s)	Example(s)	Description
mostRecent	true - get the single most recent aircraft report, only one result is returned false - don't get the most recent aircraft report, equivalent to omitting mostRecent parameter query based on aircraft report obsTime	hoursBeforeNow=1.5&mostRecent=true& minLat=30.0&maxLat=35.0& minLon=-105.1&maxLon=-95.0	All aircraft reports from the last hour and a half that fall within the min and max lon/lat are found, then out of those, the most recent one is returned.

NOTE: The mostRecent constraint is applied after all other constraints have been applied to yield only one aircraft report. This single aircraft report corresponds to the most recent in the result set defined by the other constraints. The mostRecent constraint MUST be constrained by a time range of either hoursBeforeNow or startTime/endTime. Only one aircraft report is returned.

 

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& hoursBeforeNow=3	obtain aircraft reports collected within the last 3 hours for a rectangular region (bounding box) defined by the min and max lon and lat

NOTE:

• The LonLatRect constraint can accommodate 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& hoursBeforeNow=3	obtain aircraft reports reported within the last 3 hours within 20 statute miles of -104.65,39.83 (KDEN)

 

Altitude Range

Parameter(s)	Allowed Values	Example(s)	Description
minAltitudeFt, maxAltitudeFt	any integer value (in feet) both a min and max altitude must be indicated min and max can be in any order	minAltitudeFt=10000& maxAltitudeFt=40000& hoursBeforeNow=2	obtain all aircraft reports that are greater than/equal to 10000 feet or less than/equal to 40000 feet within the past two hours.

 

Flight Path

Parameter(s)	Allowed Values	Example(s)	Description
flightPath	maximum distance in statute miles two or more way points Way points are selectable by (lon,lat), station name, or a combination of (lon,lat) with station name lon, lat are delimited by a comma (,) maximum distance MUST precede the way points maximium distance and way points are delimited by a semicolon( ;) time range: use start, end times use hoursBeforeNow default (hoursBeforeNow=1) the ordering of way points is significant: always start with origin, end with destination	flightPath=57.5; -125.27,49.95; -104.65,39.83 &hoursBeforeNow=3	obtain all aircraft reports collected in the past 3 hours for the flight path from Campbell River, BC to Denver, CO using a 57.5 statute mile maximum distance
flightPath		flightPath=57.5; -125.27,49.95; KDEN &hoursBeforeNow=3	obtain all aircraft reports collected in the past 3 hours for the flight path from Campbell River, BC to Denver, CO using a 57.5 statute mile maximum distance and the station name for DEN rather than using the (lon,lat).
flightPath		flightPath=57.5; -125.27,49.95; -104.65,39.83	same as above, except using the default time range of hoursBeforeNow=1
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 the default time range and a 57.5 statute mile maximum distance.

NOTE: Flight path results are sorted by distance along the flight path, from origin to destination. The flight path constraint cannot accommodate 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 aircraft reports collected in the past 3 hours for the flight path from Denver, CO to Orlando, FL using a 57.5 statute mile maximum distance and requesting the least dense 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 aircraft reports collected in the past 3 hours 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.
