Difference between SOTAData activation map and sotamaps.org?

Hi everybody,

could anyone explain the difference of map displays in SOTAData and SOTAmaps, please?

When checking maps of my recent activation at the EU-NA S2S event, I saw that SOTAData doesn’t display one of my S2S QSO’s.

The difference is obvious:



How did my S2S QSO with KP4/K0YT on KP4/CE-001 disappear on the map display of sotadata?

There are some known issues and bugs in the sotadata mapping which will be addressed when the person in charge - Andrew VK3ARR - can find time to do that. At the moment, yes, some QSOs do appear to “go missing” in the sotadata map, but in time those bugs will be ironed out. It is what it is, it costs us nothing at all, and we have to live with its’ imperfections. Like life, really…

Another difference between the two systems is that the SMP map has potentially more data on “non-SOTA” participants/QSO partners’ QTH positions available to it, since it uses a different DB. In particular, the DB table which the SMP map uses for QTH positions can be updated (via the activations page) by any user logged into the system, so missing data can be added, and faulty data can be corrected. That’s a feature which I am fairly certain will NEVER be included in the sotadata system.

Cheers, Rob

Dear Rob,
thanks a lot for the detailed explanation.

But if QRZ.com is not an option for the lookup of locators another option is hamqth.com.
As far as I know it is not as restricted in number of requests per day.

@VK3ARR here the info on the API:

and caching the results it a good idea I guess.
