[QGIS-it-user] La funzione $length restituisci il valore cartesiano se richiamata dalla funzione aggregate

[Totò Fiandaca via QGIS-it-user]

Buongiorno,
scrivo solo per capire se è un comportamento voluto o è un bug quanto in
oggetto.

descrizione problema:
ho un layer lineare (testOne) e una tabella (tableOne) senza geometria,
avvio il *field calc* dalla tabella e scrivo la seguente espressione, per
aggiornare l'attributo *len*:

aggregate(
layer:='testOne',
aggregate:='array_agg',
expression:=$length) [0]

il risultato (*126671,709 m*) è diverso da quello che mi aspetterei
(*126721.310
m*) , in quanto restituisce il valore cartesiano di *$length* e non quello
ellissoidico, infatti se usassi $length nel vettore testOne otterrei il
valore desiderato.

PS. il progetto è impostato correttamente con ellissoide, ovvero siamo al
corrente che:'La lunghezza calcolata da questa funzione rispetta sia
l'impostazione dell'ellissoide del progetto corrente che le impostazioni
dell'unità di distanza'

Allego dati e progetto di esempio.

Testato sia su QGIS 3.28.13 LTR Firenze che su QGIS 3.34.1 Prizren da
OSGeo4W - win 10 PRO 64b

saluti

[Luigi Pirelli via QGIS-User]

intentionally I would say:

https://github.com/qgis/QGIS-Enhancement-Proposals/issues/271

"We will port the Python implementation to C++ (including the GUI widgets
for Processing) and we will drop the custom GUI - the entry in Raster menu
will open the Processing algorithm instead. The existing custom GUI will be
dropped"

[Qgis-user] Marxan for QGIS

[Shivonne Peters via QGIS-User]

Hello,
I am writing to ask for some technical support.
I am currently trying to use Marxist to create a Marine Spatial Plan for my PhD 
thesis, this will be the first MSP for our Marine Protected Area.
I am using version 3.32.3 of QGIS and when I launch Marxan from the CLUZ plug 
in, it's keeps saying program now responding. I used CLUZ for all other stages 
and it worked fine.
Can you give me any suggestions to overcome this problem? Is the version of 
QGIS?
Any assistance would be greatly appreciated.
Thank you.

Kind regards,
Shivonne M. Peters

Re: [Qgis-user] Missing Raster Calculator in QGIS 3.34

[Lene Fischer via QGIS-User]

Hi Alex,
It sure does - but I have a feature request: Is it possible to add Resent - 
Generic as in other expressions dialogs ?.

I just stressed a bit - because I didn´e realise before now - preparing for 
lectures just after new year. And my material are from the previous version. 
But I prefer the new version because we have missed this in the Model Builder. 
So thanks!!
Regards
Lene

Emne: Re: [Qgis-user] Missing Raster Calculator in QGIS 3.34

Hi Lene,

raster calculator is not missing, it is still there and the dialog you see is 
the one you are looking for. This algorithm was ported to C++ earlier this year 
and the algorithm dialog was unified with the rest of Processing tools. Also 
there were some other changes aimed to fix several issues which made the raster 
calculator algorithm unusable in the modeler context.

As for the predefined expressions functionality, it was removed as a result of 
discussion between QGIS developers involved in Processing maintenance. It was 
not missed or forgotten, it was an intended move.

Hope this helps
