[Qgis-user] change pixel value from no data to zero

Hi to all, I am using qgis 3.16. I have a raster file that I created from shapefile of polygons (rasterize of GDAL) using a column that has the number 9 every where there are the polygons. This raster has 2 different values in the pixel: not data and 9. I need to have 0 (zero) instead of no data.

Re: [QGIS-it-user] Apertura dei progetti direttamente da cartella evitando però le aperture multiple di QGIS

Ciao Salvatore e Marco, effettivamente si tratta di una possibilità già proposta qualche anno fa [1] e che si iniziò anche ad implementare [2] [3] in vista di QGIS 4. Quindi, le basi mi pare che ci siano, ma il problema è che bisogna modificare 1000/2000 righe di codice [4]... Penso che

Re: [QGIS-it-user] Apertura dei progetti direttamente da cartella evitando però le aperture multiple di QGIS

Se con il termine "progetto" si volesse, seppur impropriamente, intendere solo la componente "mappa" del progetto stesso, cioè l'area di lavoro dove vengono rappresentati i diversi temi geografici, allora la funzionalità richiesta potrebbe avere un'utilità pratica, specie nella composizione

Re: [Qgis-user] Export Attributes to Excel and import back edited

Actually, for point layers - there's a better workflow. Use the 'Add geometry attributes' tool to add X and Y columns before exporting to Excel. After you change your values, use the Processing Toolbox -> Create Points layer from Table which can read Excel file directly from disk and give you a

Re: [Qgis-user] Export Attributes to Excel and import back edited

Right click -> Export -> Save Features As and select 'MS Office Open XML spreadsheet'. Save it as a '.xlsx' file. Once you are done editing, drag-and-drop it to QGIS and it will be imported as a table. If you want the shapes, you'll have to join the table to the original layer using 'Join

Re: [Qgis-user] Editing my map

Hi, "Is there a better way to do this?" Yes, try Vector/geoprocessing tools/clip.  Select the US, in the countries files, select "district" as input layer in the clip tool GUI and the country file as the Ovelay layer (use selected features only if you have pre-selected the US). Good luck

Hi Nicole An other idea is to use a version control system where you need to check-in and check-out the projects. https://www.perforce.com/ has this kind of feature. But this would add another system to your infrastructure and as such it is not a light weight solution for you problem. Best

[Qgis-user] Several users working with one project file - warning

Dear QGIS-users, we are several people, sometimes working on the same QGIS-project without knowing it. Unfortunately you never get a warning that anyone else is currently working on the project, when opening the project file. That is why I would like to generate a warning, that person xy is
