The new QGIS 2.10 (Pisa) has been released, with many great new features, tweaks and enhancements. Check out the changelog for the highlights (you’ll need some time, it is again an impressive list of improvements and new features).
The source code and binaries for Windows, Debian and Ubuntu are already available via the large download link on the QGIS home page. More packages will follow as soon as the package maintainers finish their work.
A big thanks to the developers, this is again an impressive piece of work!
In a recent post Anita Graser (aka underdark) showed how to create illuminated or Tanaka contours in QGIS using various functions available in the toolbox and some custom functions.
Here I want to explore a slightly different way to achieve the same, using GRASS GIS to compute the azimuth, brightness and line width. I’ll use the command line, but you can do the same using the menu in GRASS, or the corresponding GRASS functions in the QGIS processing toolbox.
This new feature created by Nyall Dawson and funded through crowd funding really sets new limits in terms of what is possible in terms of cartography. Check out Nyall’s post Introducing QGIS live layer effects! for a walk through of the new possibilities that this features brings to QGIS. It will be available in version 2.10, or if you can’t wait you download a QGIS development snapshot from the QGIS website to help in testing.
QGIS Brighton (2.6) is out, with tons of new features and improvements. Check it out on http://qgis.org/.
For an overview of the new features, check out this change log. You really should check it out. I just had a look and although I am using the trunk and beta versions for some time now, I still noticed quite a few new features I hadn’t discovered yet!
In a by now fairly old post I described how to sample raster values at point location in QGIS. The method I described used the ‘Point Sampling Tool’ addon. However, the function creates a new point layer, which only contains the values extracted from the raster layer. None of the fields in the original point layer is copied to the new one. It is possible to join the attribute table of the new vector point layer with the original attribute table afterwards using a spatial join as explained in that post. However, this will not work if your point data includes points with exactly the same coordinates.
Since I wrote that post, QGIS has come a long way. Continue reading
Just a few days after the release of GRASS GIS 6.4.4, now the latest and greatest QGIS Chugiak. And this new version comes with a whole bunch of improvements and new features. Check out this nice visual visual changelog of the major changes or go straight to the download page to try it out yourself.
Some notes to self about steps I had to take to make GDAL work from within QGIS. Both where compiled from source and run without problems. However, there are still a few issues with running gdal from the QGIS processing toolbox. This may have to do with the fact that I installed both in a non-default location (in the /usr/local/ folder), but in any case, the steps below solved the problem for me. Continue reading
