[Qgis-user] Proportional Symbols Bug in 3.2?

Hi QGIS User Community! I am attempting to represent water utilities (points) using *graduated symbols* (by size), and would like the symbols to be *proportional* to the number of customers. I thought that this could be done be done under the symbology dialogue box by selecting "graduated" and

Salve a tutti, l'algoritmo in oggetto crea un vettore di output con un campo integer, questo esclude tutti i casi in cui il raster ha valori con virgola. Secondo voi è un bug da segnalare?? saluti - https://pigrecoinfinito.wordpress.com/ -- Sent from:

[Qgis-user] qgis3 uses IE as default browser on windows10?

Hi, Is there a setting in qgis3 to change the default browser used by processes? For instance, qgis2web opens a webbrowser after exporting the webmap. In qgis2.18 my default browser Firefox was opened. Now, qgis3.4.4 it opens IE. According to Tom Chadwin (qgis2web) the plugin refers to a

Ciao a tutti, sto utilizzando l'algoritmo k-means di SAGA tramite QGIS. I vari raster che entrano come input per questo algoritmo, provengono tutti dal medesimo DEM, il quale è stato ottenuto da un "ritaglio" di un modello digitale molto più esteso. L'algoritmo non viene nemmeno eseguito ed

Re: [Qgis-user] nodata and raster calc

Hi, In 99 % of what I do, treating nodata in any other way than a data mask would be severely detrimental to my results. This would include OR and AND. (The scientific equivalence of “Do you want it eat pizza or ‘I don’t know’? or Do you want to eat pizza or nothing?” are two different valid

No, no, io lascerei così com'è guarda ...se ci sono arrivato io (che, di comprendonio, sono più tosto del legno) a capire (anche se l'ho capito in ritardo) che "Figli" si riferiva a un gerarchicamente più elevato "Parent", vuol dire che lo può capire chiunque abbia il pollice opponibile

Ok, I have no idea what went wrong the first time - I just ended up with lots of graphics and no records in tables - but starting a new project, creating a new geopackage with regular polygon as geometry type the tool now works as I expected - geometries and records are added to the attribute

[Qgis-user] QGIS 3.4.4 add ellipse

Dear list, I just discovered that QGIS 3 has the nice option to add ellipses in the editing toolbar. Does this just add a graphic to the map? I was hoping I could add a polygon in the shape of an ellipse to a vector layer. I have tried both with a shape file (polygon) and with a geopackage

Credo di aver tradotto io i "termini incriminati" e ricordo di aver avuto molti dubbi in proposito. Ogni suggerimento è ben accetto cmq. Nello specifico poi ho usato la traduzione "genitore" per "parent" sia perché è quella corretta sia perché ci possono essere vari gruppi annidati uno nell'

Re: [Qgis-user] nodata and raster calc

In fact I would always expect nodata. nodata is what it says: no data. How can one calculate or generate new values with one unknown term. Especially in the case of boolean. Lets take an example from real life. You have the information of wet or not wet area. In the case of wet you have to

Re: [Qgis-user] nodata and raster calc

I absolutely agree. For the Discussion. nodata is a valuable information, and is getting lost when dealing as desired value. Although the OR part needs more Discussion. For consistency that has to be nodata as well. What about nodata OR 0? In my opinion nodata always needs a discrete
