I have been looking for some time for a way to display the location of my contacts on Google Maps after a SOTA or WWFF activation, or after a day of SOTA chasing.

As I could not find what I was looking for, I decided to write it myself, and it does now the minimum I expected: you just paste a log in the ADIF, Cabrillo or SOTA format on the page, and the program tries to find the location of the contacts and shows them on a Google Map.

You might find it funny too :wink:

Comments and suggestions are welcome.


Happy New Year !



Very nice tool. I was already using you ADIF 2 SOTA and SOTA callsign checker tools. Both tools are very useful for an activator. Thank you very much.

Very nice Christohe,
I just input my last Sota Log from F/AM-418 (83 qso).
All show on the map except those:
•Could not determine the position of OE5EEP/P
•Could not determine the position of LA1ENA/P
•Could not determine the position of EA2CW/P
•Could not determine the position of I1YDT/P
•Could not determine the position of HB0/DK3RED/P
•Could not determine the position of OH7BF
•Could not determine the position of OH2NOS/P
•Could not determine the position of GW4ISJ/P

83 lines processed, 75 positions on map

Hello Gerald,

Bear in mind that the program has to figure out the coordinates of each station from what is in the log line.

"Could not determine the position of …’ means that the position could not be found, for example because

  • there are no coordinates or summit reference in the log line
  • the station was /p or /m
  • there is no position available for this call in the QRZ.com database.


Great tool and easy to use. Thanks for your efforts and initiative.

Happy New Year, Gene KC3RT

Hi Christophe,

I just hang around and wait until they appear on SMP.
I’m not sure how long we have to wait until the next import of data into SMP, but I see your activations up to
ON/ON-016 - Les Aisances (09/02/14) are available. (below)

Perhaps Rob or Andy can tell us the status of the uploads.

In the meantime your tool will fill the gap nicely.


I hesitated before starting developing Log2Map for that reason :wink:

And that is why I tried to do something different, that also works with SOTA chaser logs, or ADIF logs of other kinds of activations (WWFF, etc.), or Cabrillo for contests.

It does not look yet as nice as SMP , though :wink: I still have a lot to learn about the Google Maps features…


I received several questions about the way the locations displayed by Log2Map are obtained, and here is some clarification.

The purpose of Log2Map is to display the location of the stations contacted on Google Maps.

It is not limited to SOTA activators: any log (SOTA/WWFF activators/chasers-hunters, contests, etc.) formatted in ADIF, Cabrillo or SOTA CSV, can be used, as long as its size is less than about 100 kB (might change).

The locations shown on the map are determined using the following information in this order:

  • the SOTA summit reference from ADIF (“sota_ref”) and the SOTA logs
  • the latitude/longitude from ADIF (“lat”, “lon”)
  • the Maidenhead Locator from ADIF (“gridsquare”)
  • the location provided by QRZ.com for the callsign (callsigns without prefix/suffix only)

Of course, for callsigns with a prefix (EA8/ON6ZQ) or a suffix (ON6ZQ/P), the location cannot be displayed if not explicitly specified (SOTA reference, grid or lat/lon).

Let me know if I can help.


Just tried your application. It is very nice!
Thank you Christophe!

By the way, you can share the link to the map, for example when writing about your activity on the reflector, like http://www.on6zq.be/p/Log2Map/index.php?log=1420544459853770641

The link will work for two months (may change).
