Also QGIS allows to create custom scale lists and switch between scales by selecting desired value from the scale combobox in the main window statusbar. пт, 21 лют. 2020 о 00:48 Nyall Dawson пише: > > On Fri, 21 Feb 2020 at 05:37, C Hamilton wrote: > > > > We have written a plugin that fixes the scale of the QGIS canvas to match > > the integral size of EPSG:3857 map server tiles.

Richard, Thanks for that information. I meant plugins.qgis.org. From the URL you sent it looks like it has many of the components and it gives me ideas for EPSG:4326. Unless someone else is working on this I will submit a plugin after I see if I can make it work with other CRS tile caches.

Re: [Qgis-user] [QGIS-Developer] Zoom to Scale Plugin - Should we include it on qgis.org?
Hi Chris, One year ago I proposed the following: a tree embedded widget to be used for WMS/WMTS layers. It uses the functionality which is in the Juergens Tile Scale Panel: http://www.qgis.nl/2019/02/14/about-layer-tree-embedded-widgets-and-have-your-wmts-always-crispy-sharp/?lang=en Probably you mean something else? As it is not resizing the servertiles, but 'clicking' to the right scales (coming from the capability documents) of the active layer. If you mean plugins.qgis.org when you talk 'adding it to the repo' I would say yes! Why not? If you say add it by default to QGIS, I'd say: let's first see and check it out as plugin :-) Also (see discussion about resources plugin) adding python plugins to QGIS installs has some drawbacks.

[Qgis-user] Zoom to Scale Plugin - Should we include it on qgis.org?
We have written a plugin that fixes the scale of the QGIS canvas to match the integral size of EPSG:3857 map server tiles. This way there is no degradation of the images by transformation. This has some similarities to the QGIS 2 plugin called Tile Map Scale Plugin which was never updated for QGIS 3. This only works with EPSG:3857 projections. I wish I could figure out a way to also match an EPSG:4326 tile cache to the canvas scale size, but I cannot use the map scale to calculate this because it changes as you move around. Would you be interested in having this plugin added into the QGIS repo? Unlike the Tile Map Scale Plugin ours only has a single toggle button to lock or unlock the QGIS scale to one of the predefined scales. Let me know what you think?

Re: [Qgis-user] Thoughts on QGIS Development and LTR Releases
Hi Chris, I share most of your concerns, as much as I advocate the spread of QGIS in enterprise and organisations. It is true we need always more reliability, documentation. I'd like also to point that 2.x is not so far away, and that the reliability have since improved by order of magnitude. Let's also keep in mind that the level of expectations of users grows very fast too, so this is a race that will never end ;-) However, I think there is a cultural problem, and probably a pedagogy effort we should make. LTR does not mean stable. LTR means it will gain bugfixes longer than releases. So it is highly expectable that installing a LTR in its early versions will let you hit more issues. I remember the very same situation for ArcGIS 8 or 9 early stages. And this is the very same for linux distributions or any software. I don't remember any early x.0 release in QGIS that was not followed one week later by an urgent point release. But new users don't know this. They see a big green button "download that sexy new version". That said, how to improve the situation? After years of discussions in the various events, hackfest, conferences, discussions with public or private customers, developpers, here are the possible leads we have: - Keep on explaining the rationale and codes of free software to users and potential funders. - Try to keep our "power users / early testers" population, so that we target the right issues during bugfix sprints. - Offer longer LTR lifespan, so that funders have a larger window to actually find and have bug fixed. - Keep on explaining that QGIS bugfix release should be easily deployable in big organisations. OSGEO4W silent installs allows this. Maybe going toward auto upgrade / patch system could help (it's a big effort though) - Keep on gaining more budget for QGIS.org, so that we can setup a real semi automated Q/A acceptance test suite. This requires human tests. Boundless did, it is possible. It is a matter of ressources. Should it be centralized or community powered ? I have no idea, but this requires someone to be hired all year long to do this. IMO, enterprises requiring such reliability should really consider sponsoring this framework and dedicate some human ressources. - Same goes for documentation - Same goes for code review, we need to have more reviewers. the learning curve is steep though, and we need to find money for this - Improve the website with a simple page, with graphics and videos on what is the lifecycle of QGIS, and what version to use for what expectations. A note about QGIS.org budget. To me, it is only a leverage, a catalyser, but it can't fund itself a full QA infrastructure with the current economic model of the association. I think, this is our responsability to spread this word everywhere so that the user / contributor rate changes a bit. After all, even Microsoft with its thousands of testers, and its early testing network was able to push updates causing the famous Blue Screen Of the Death. So shit can happen. Packaging nightmare with major changes in underlying libraries remains a really really complex process. How fast we are to fix and change our ways to do is the real question. I think the QGIS and OSGeo Community does a tremendeous work.

[Qgis-user] Thoughts on QGIS Development and LTR Releases
I first want to say how much I appreciate all of the QGIS developers and all of your hard work, but I would also like to suggest that you exercise caution when you label a release LTR. I work in a large organization where most geospatial analysts can have access to ArcGIS if they want it. The advantage to ArcGIS is that everyone has been trained to use it, ESRI has been around for a long time and there is a lot of documentation, training and support for it. So why would users want to use QGIS? There are always a curious few who see QGIS and realize they can download it for free at home. They tinker with it and come to like it and then they try it in the workplace. For the users who have ArcGIS at their disposal there must be a good reason to use QGIS instead. These tend to be the reasons they use QGIS: 1) It does not crash as much as ArcGIS. 2) It is faster than ArcGIS. 3) It can effectively processing larger data sets than ArcGIS. 4) There may be some workflow in QGIS that is simpler than in ArcGIS. I think that the QGIS community can be proud about the fact that most of my users who start using QGIS love it and don't want to go back to ArcGIS if at all possible. If a user finds that their reason for using QGIS goes away, they will be disappointed, but will to go back to ArcGIS. I am an advocate for QGIS in our work place. I think it should be used more, but it is really, really hard to convince most people. Most of my users are not programmers so if something is broken they don' t know how to fix it. We have QGIS support contracts which help. Users consider the QGIS LTR to be a stable release. If you release the LTR before it is stable, then that can have bad consequences to our user base. QGIS 3.10.2 probably should not have been labeled LTR, but I have been actively telling our workforce not to use 3.10 yet. 3.10.2 still seems to have some serious bugs as it is frequently crashing (negating one of the reasons for using QGIS). There must be a WMTS problem that is causing it to crash and I have had a report that there is a serious memory bug. I am hoping that 3.10.3 will have solved most of these problems, but I am not going to count on it until I test it. Everyone has different uses for QGIS and different workflows and each person's experiences are going to be different, but I would suggest that you don't mark a release LTR until it is reliable. Additionally, I suggest that you never back port major libraries or capabilities into the LTR like what happened last fall. Only fix the bugs. As saying goes, "If it isn't broken, don't fix it." I still have users on QGIS 2.x and they love it and it works for their needs. I share this with you in the hope that it is helpful.

Re: [Qgis-user] QGIS uninstalled after GDAL PPA install
Hi again Andre, Thanks for that, I more or less get what you mean. The problem is that when I ran autoremove it came back with almost a gig of dependencies it wanted to remove, so I cancelled it! QGIS wasn't the last program I installed so I have no idea how to purge only the dependencies directly related to the previous version of it I was running. If I run autoremove and it damages other applications or makes my system unusable then I won't be able to fix it (I'm only a user, I've got no background in programming). I read around and people warned strongly against doing this unless you're sure what you want to remove. How can I be sure I only remove the right dependencies? Does QGIS have a list or something I can use as a guide? If anyone could explain how to use Synaptic package manager then I'd be really grateful! It must have the most unintuitive interface of any piece of software I've ever tried to use.. I edited the source file last time I installed it, so that part is done. Incidentally, I don't see the 'other Software' tab in the Ubuntu Software Center, so I just edited it manually. Any idea what that package is called? I'm happy enough using the terminal if I know (roughly) what I'm doing! Thanks a lot team, Jimi. On Wed, Feb 19, 2020 at 8:18 PM Andre Joost wrote: > Am 18.02.20 um 23:58 schrieb J.

[Qgis-user] QGIS release confusion
Hi! I am a bit confused about the current QGIS releases. The splash screen for QGIS 3.10.2 says Long Term Release, but the download page maintains that 3.4.15 is the LTR. or Long Term Release Repositories (LTRR?). Instructions for the Network installer says "To get the *long term release* (that is not also the latest release)..." Which one would that be? And the road map says that 3.10.3 will be LR/PR, due tomorrow. And no LTR until october. Is there a difference between Long Term Release and Long Term Repositories? The release schedule says "four monthly releases with LTRs in late february". Please clarify.

[Qgis-user] Semi Automatic Classification Plugin and Python3.8
Hi all, it's my first message here and i hope to be ok with this. I use manjaro linux (based on arch) which comes with python3.8 right now. I have a problem with the plugin Semi Automatic Classification that calls a python error: >EndT = cfg.timeSCP.clock() >AttributeError: module 'time' has no attribute 'clock' Googling i found out that it might not like python 3.8, so i am trying to run qgis with python3.7 with no success. I tryied venv also, but it seems that qgis in venv does not even load python. The 3.7 version is apparently running on my machine infact: > $ python3.7 > Python 3.7.6 (default, Feb 20 2020, 09:49:29) [...] Hoping for any tip, Giovanni Rossetto ___ Qgis-user mailing list Qgis-user@lists.osgeo.org List info: https://lists.osgeo.org/mailman/listinfo/qgis-user Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-user
