FAQ¶

Как задать вопрос по 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:

• письмо должно иметь содержательную тему

• какую версию QGIS вы используете (точный ответ)

• 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)

  • укажите используемую операционную систему и её версию

  • каким образом она была установлена (OSGeo4W? автономный установщик? собственная сборка?)

  • 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.

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.

Могу ли я открывать файлы ECW в QGIS?¶

Да, можете… НО в зависимости от используемой операционной системы это может быть не так просто.

If you are under Windows and are using the OSGeo4w installer, it is included.

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

Can I compile QGIS myself?¶
