Come fare una domanda su QGIS?

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:

  • preferibilmente un titolo descrittivo nell’oggetto della tua mail
  • Quale versione di QGIS hai usato in quel momento (esatta)
  • 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)
    • Sistema Operativo in uso e versione
    • come l’hai installato (osgeo4w? installer-standalone? Una versione da te compilata?)
    • 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 Bug, Richieste e Segnalazioni.
