Title
This is a list of supported deep links and URL parameters for aprs.fi. Please use these methods to link from your web page to this site - these are the ones that are likely to stay around longer.
If you would like to have a live APRS map on your own web page, you might want to try embedding the aprs map. For example, take a look at OH7AA's repeaters and digipeaters page.
Map, tracking a callsign:
http://aprs.fi/N0CALL
The above method only works with targets which consist of numbers, letters and the minus (-) character. No spaces or other non-APRS-callsign characters are permitted in this short link format. If you wish to link to a non-callsign target (like an item, object or AIS vessel with spaces) you need to use the longer format and remember to URL encode the callsign (a space becomes %20 - look up the target name by entering it in the tracking form and check what appears on the URL bar of your browser):
http://aprs.fi/?call=N0CALL
http://aprs.fi/?call=NORDIC%20JET
If you wish to specify a time range for the track line, enter it in the timerange parameter as seconds (again, this won't work in the short link format):
http://aprs.fi/?call=N0CALL&timerange=86400
Map, centered at coordinates:
http://aprs.fi/?lat=68.8020&lng=16.6113
Enter the latitude and longitude in the lat and lng parameters, in decimal format. Latitude in the southern hemisphere is negative, and so is longitude in the west. You can look up the decimal coordinates using the map view by selecting decimal coordinates from the Options.
Specifying zoom level and map type:
Zoom level (url parameter z) is specified as an integer value: 1 is completely zoomed out, showing the whole world, 19 is the maximum zoom level.
Map type goes in the mt parameter. Supported values are m for Map, k for Satellite (don't ask why) and h for hybrid Map-Satellite view.
http://aprs.fi/?lat=40.6914&lng=-74.0160&z=19&mt=k
http://aprs.fi/?lat=62.9030&lng=27.6677&z=11&mt=h
Static map:
The static map can currently only be centered on a callsign. Please note that you really do need to link to the web page containing the static map, it's not possible to embed the map image itself using an img src tag. Zoom level (url parameter z) is specified as an integer value: 1 is completely zoomed out, showing the whole world, 14 is the maximum zoom level.
http://aprs.fi/static/N0CALL
http://aprs.fi/static/N0CALL?z=12
Station info page:
http://aprs.fi/info/N0CALL
http://aprs.fi/info/NORDIC%20JET
This link does not have any other URL parameters. If the callsign has spaces or other special characters, they need to be URL encoded.
Weather report page:
http://aprs.fi/weather/OH2KXH
http://aprs.fi/weather/OH2KXH/day
http://aprs.fi/weather/OH2KXH/week
Works much like the info page link. It currently defaults to a 48 hour view. The view can be specified by adding one of these specifiers in the end: day, week, month, year.
Things not to do:
Please do not try to use the n= parameter when linking. The callsign/nickname entered on the login page is hoped to belong to the visitor, not the APRS user linking to this site. The login page retains the URL parameters described here - after entering a nickname, the user will end up on the deep-linked page.
