| Constraint Type |
Parameter(s) |
Allowed Values |
Example(s) |
Description |
| LonLatRect |
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.
| Constraint Type |
Parameter(s) |
Allowed Values |
Example(s) |
Description |
| Radial Distance |
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) |
| Constraint Type |
Parameter(s) |
Allowed Values |
Example(s) |
Description |
| Flight Path |
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=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.
| Constraint Type |
Parameter(s) |
Allowed Values |
Example(s) |
Description |
| Density |
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.
|
| Density |
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.
|
| Constraint Type |
Parameter(s) |
Allowed Values |
Example(s) |
Description |
| Field Parameters |
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.
