Re: [Qgis-user] Creating raster difference for many small rasters

Hi, Can you use the zonal statistics in the processing tools? It’s not the plugin. Nicolas Cadieux Ça va bien aller! > Le 17 avr. 2020 à 11:04, joolek a écrit : > >  > Hi Everyone, > > I have failed looking for a solution. And using latest QGIS so can't use > Zonal Statistic Plugin > > I

Salve, vi sottopongo questa situazione, per capire se é una cosa che si possa modificare "facilmente", o debba entrae in questione complesse del CORE di QGIS. Ho un file CSV, con piú di 1 milione di linee. Ad importarlo come punti, ed a usare la tabella attributi, ho notato velocitá in un

Re: [Qgis-user] topology checker - Check if point features are covered by line features

Hi, Small correction, If you extract the end nodes (vertices) of the line, you can use the following rule.  End node layer must be covered by endpoints of line layer or node layer must be covered by line.  I therefore assume the QGIS topology checker can work for endnode only and not for

Michel, Thank you for your response, and for putting some good geometry generator examples out for others to learn from. (If others on the list haven't seen them, they are at: https://gitlab.com/GIS-projects/qgis-geometry-generator-examples) Your suggestion worked for me. I am mapping in EPSG

Re: [Qgis-user] topology checker - Check if point features are covered by line features

Hi Marshal, I looked at your data. The first problem is that none or your line nodes intersect with a point.  It looks close... but it's not close enough.  By using "snap geometry location", I was able to create a new line that snaps to your point.  (called Topologie snapped_line in the file

[Qgis-user] Creating raster difference for many small rasters

Hi Everyone, I have failed looking for a solution. And using latest QGIS so can't use Zonal Statistic Plugin I basically have almost a hundred of small asc grids, from two different data sets. They overlap and I'd like to calculate difference between them... not as a one value but difference for

Grazie a tutti per il suggerimento. La mia é stata una svista, in realtà avete ragione. Sto provando a replicare un codice per poter fare un override di un drop event tra una listwidget e una tablewidget splittando i nomi dei file che seleziono e sposto e sto avendo parecchie difficoltà. Spero

Ciao Enzo, perché non usare una normale stringa di python? Hai qualche vantaggio specifico con una QString? Matteo ___ QGIS-it-user mailing list QGIS-it-user@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/qgis-it-user

Re: [Qgis-user] geometry generator - unexpected results

The numbers you need to use in “rand(-10, 10), rand(-10, 10)” depend on the CRS of your layer. I tested it with some demo data in EPSG:31370 and I got a similar result as you. When I changed those numbers I got a better result. After you changed those, you can play around with that 100 inside
