Kaip užduoti QGIS klausimą?

If you are going to ask QGIS related question via the mailing lists, please provide enough information to help others easily understand what your problem is. Without a clear and precise question, it is very hard to answer for anybody or takes just too much time because the answer will be a question to you etc etc. You may provide information such as:

  • pageidautina informatyvią jūsų laiško antraštę

  • kurią QGIS versiją jūs naudojate šiuo metu (tiksliai)

  • what are you expecting to get

  • if applicable, what have you tried and the result you got

  • if your question is about something broken, you may also provide:

    • what exactly is the error (if possible: screendump, stacktrace, copy of error text)

    • kuri operacinė sistema ir versija

    • kaip įdiegėte (osgeo4w? atskiras diegimas? patys susikompiliavote?)

    • at what time did it break (reinstall, new install, system update, project changes)

Keep in mind that the more precise is your question, the quicker and more accurate can be the answer.


In case of a broken function, you may give a look at QGIS issue tracker before mailing to the list. More information at Riktai, savybės ir problemos.

How are QGIS release names selected?

After a successful developer meeting in Zurich (Switzerland), we decided that the next release should be related to it. Since then, all releases have been named after locations of our developer meetings.

I created a map with QGIS, do I have to mention QGIS?

There is no requirement to mention QGIS for maps produced with it. It is of course really welcome if would like to add a note saying that the map was produced with QGIS. „Made with QGIS“ or „Map created using the Free and Open Source QGIS“ are good examples of such a note.


Do not say ©QGIS as QGIS does not hold copyrights on your work.

Ar galiu atverti ECS failus su QGIS?
