[QGIS-Developer] r.series of GRASS not working in pyqgis
Hi devs, I'm facing something really weird using r.series. The tool, beside the open ticket [0] is working nice. What is really really weird is that while with the UI I can generate the aggregated raster, when I copy and paste in the python console within QGIS the exact same command (with output saved in a folder), I get no error but at the same time no output. Other GRASS tools (e.g. r.info) seem working fine. If someone wants to test, you can use the raster attached in the ticket: just be careful to change the Max parameter in the Advanced Parameter to e.g. 1.

Hi Tim, Thanks Sunni!

Well, if you want to configure it from the data, it should be possible (or I should make it possible) to do it from the symbol. Since we can use an expression to configure the symbol, it's mean we can also configure the billboard also. Hopefully, I can show how to do it in this week. Best regards.

Re: [QGIS-Developer] Dropping the extra label placement algorithms?
Yes, if you consider trial and error a mindful method, I "use" label placement algorithms when preparing a cartographic layout for printing. I mainly work on geographic data and web output, so it's not frequent and I follow the easy and dumb way: I swap algorithms, hoping for a result that solves cluttering in the worst spots, until it fits – usually it fits here and it's out of order elsewhere... I generally criticise this approach, but when looking for a good appearance, it seems bearable. Yes, I would need some more information to do a better work. As already said, I think this is a cartographic issue that can get more benefits by a better GIS approach. Label positioning is not "substantial" but can exploit proper data. Say population for a populated place. Using these algorithms on top of geometric-only data gives little more than casual results. I had the opportunity to weight the theory behind these methods starting from the obituary of Mitchell Jay Feigenbaum by Maurizio Codogno on ilPost.it that referenced the New York Times: https://www.nytimes.com/2019/07/18/science/mitchell-feigenbaum-dead.html. Looking to further developments, I think there is not a "best" algorithm, but that it's useful to keep alternatives. I doubt the algorithms could really work well without an interface that can reach useful data, but I also think that keeping them available without any special interface could keep them in a place that is not really influenced by the frequent enhancements of QGIS. c On Mon, Jul 29, 2019 at 8:31 AM Nyall Dawson wrote: > On Mon, 29 Jul 2019 at 16:28, Carlo A.

As stated in the earlier email, I would not mind if we remove those. Are you thinking about removing the option in GUI or to get rid of the code in PAL for other methods too? > I don't think ANYONE knows what these mean, and it's a heck of a lot > of code (which needs fixes) to cart around for no compelling reason > that I can see. > > I have no particular preference to any of the methods, so would > happily accept a different default if anyone out there can point to > which method is best! > > Googling pop music / tabu / chain only gives a handful of results > relating to QGIS labeling engine. And googling for "falp" sounds like > something that would get you flagged on your company's firewall. To shed some light on the methods for those interested... a good starting point is PAL docs [1] with links to papers, unfortunately most links there are broken, but this paper is a good start: Laurent et al: From Point Feature Label Placement to Map Labelling (2009) The paper is available here [2] and gives an overview of the whole process of labeling with PAL. Generally the idea is to turn labeling into a general combinatoric problem and then apply some heuristic. The paper also covers the various optimization techniques. FALP seems to be the most basic initial solution. "Tabu" seems to be a meta-heuristic method from 1980's [3], "chain" stands for "ejection chains" concept somehow related to Tabu search. And finally Popmusic is a search method co-authored from one of the authors of PAL. I remember there was a paper with quite extensive testing of the methods, but can't find it anymore. From what I remember, one would higher amount of labeled features with a slower method (e.g. Popmusic) or fewer labels with a faster method. If we decide to stick with a single method, it may be interesting to get the opinion of original PAL authors on what method to choose... I don't know enough about those methods to decide.
