Como preguntar unha cuestión de 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:

  • preferentemente un título descritivo para o correo electrónico

  • que versión de QGIS utilizaches naquel momento (exacto)

  • que agardas obter

  • se é aplicable, que foi o que tentaches e o resultado que obtiveches

  • se a túa pregunta é acerca de algo estragado, tamén podes indicar:

    • cal é exactamente o erro (de ser posible: captura de pantalla, stacktrace, copia do texto de erro)

    • que Sistema Operativo e que versión

    • como o instalaches (osgeo4w? instalador autónomo? compilado por ti?)

    • en que intre se estragou (reinstalación, nova instalación, actualización do sistema, mudanzas do proxecto)

Ten en conta que canto máis precisa sexa a pregunta, máis rápido e máis precisa pode ser a resposta.

Note

In case of a broken function, you may give a look at QGIS issue tracker before mailing to the list. More information at Erros, Características e Incidencias.

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.

Note

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

Podo abrir ficheiros ECW con QGIS?

Si que podes… PERO dependendo do teu Sistema Operativo, é máis ou menos difícil.

Se estás en Windows e empregas o instalador OSGeo4w, está incluído.

If you are using macOS, you can find the ECW plugin and install instructions at https://www.kyngchaos.com/software/frameworks

For other instructions, eg look here: https://www.faunalia.eu/en/blog/2019-05-21_ecw_support
