Re: [QGIS-Developer] Tool to create Mesh from raster layer?
Hi Andreas, Indeed, there is no native tool at the moment to convert raster directly to mesh. I filed a ticket with a link to this discussion so we can add it to QGIS later: https://github.com/qgis/QGIS/issues/52313 But, in general, I would first try to find the source of the DEM raster (e.g. point cloud or spot survey) and use the raw data to create the mesh. This will avoid double interpolation :) Kind regards Saber On Mon, 20 Mar 2023 at 14:31, Andreas Neumann via QGIS-Developer < qgis-developer@lists.osgeo.org> wrote: > and there seems to be https://github.com/heremaps/tin-terrain > > However, I am looking for a solution integrated in QGIS ... > > On 2023-03-20 14:28, Andreas Neumann via QGIS-Developer wrote: > > Hi, > > Yes - exporting the raster to xyz points or to contour lines are both > workarounds. > > It would be nice, if QGIS would gain a direct algorithm of creating a mesh > from a DEM - as many DTMs are provided as raster.

Hi Andreas, There should be a tool to convert vector to mesh (under Processing > Mesh > TIN Mesh Creation). There will also be some new Processing tools for handling point clouds.

Re: [QGIS-Developer] Re-discussing the QGIS release schedule - in combination with the quarantine rule for LTR versions
Hi Andreas, Thanks for raising this issue. >From our experience with various large organizations, they generally skip most of the minor releases. But for those who fund a specific bug fix, they will immediately upgrade to the latest LTR as soon as the fix appears in the release. So, having the current regular releases of LTR suits both sets of users. The LTR releases can be skipped for most organisations but also crucial for those who pay to fix a bug in QGIS master and get backported to LTR.

[QGIS-Developer] Point cloud processing, elevation profile & 3D maps enhancements crowdfunding
Dear QGIS community, We have only 2 weeks left on our crowdfunding campaign to bring lots of exciting new features to QGIS: https://www.lutraconsulting.co.uk/crowdfunding/pointcloud-processing-qgis/ So far, we have only managed to raise 25% of the target funds. If you work within a large organization who benefits from using free and open source QGIS, it is time to ask them to contribute, because free software costs money to develop and maintain. Without your support, it will not be possible to add features like these.

Re: [QGIS-Developer] Problems with MAC and OneDrive
Hi Allen, It is possible to use GeoPackages and synchronise them across multiple devices/platforms (including mobile devices through https://inputapp.io which is based on QGIS) using Mergin service ( https://public.cloudmergin.com/ and for your own hosting: https://github.com/lutraconsulting/mergin). This allows you offline editing, collaboration with other users and tracking changes. Kind regards Saber On Tue, 5 Apr 2022 at 00:34, Carlo A.
