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.
You may be aware that there is also a GRASS GIS version 7. So which version should you go for? Well, it depends. Is long-term support, backward-compatibility with the GRASS 6 line and stability important to you. Or do you use the QGIS GRASS GIS toolbox a lot (which is not yet compatible with GRASS 7)? Go for the new GRASS 6.4 series.
Are you always looking for the latest of the latests, or is speed or the ability to handle very large data sets important to you? Have a look at list of new and improved features in GRASS 7. It is still in beta, so in theory less stable. But I should add that I am using this version for some time now (on Linux) and in my experience it is very stable.
Of course, you can also install both, they should run happily next to each other.
After a long wait, GRASS 7.0 beta is out! See here a summary of what is new in this release. Take your time, is is a long list :-).
In fact, GRASS 7.0 has been available for some time now for those willing to compile it themselves. So have I, and out of experience I can tell you, this is a great release, with tons of new features and improvements, including great speed improvements in handling vector layers, a whole new module for time series analysis, numerous interface improvements, etc.
Really, you should go over to the download page and give it a try! Good change you won’t look back after that.
Are you one of those people eagerly waiting for all those new features in QGIS that have been mentioned in the last couple of months on various forums and blogs? Well, the waiting is (almost) over. QGIS 2.2 is already available in OSgeo4W, Fedora, and Debian, while binary packages are being updated and will be available any time (or might already be available by the time your read this) on qgis.org.

And it is looking great. I have been using the master (development) version for some time now, so I can tell you out of experience that this release rocks! Some of my favourites are the greatly improved map composer, great new styling features, integration of Sextante in QGIS core and much improved stability. For a list of major changes and new functions, go here. But, of course, don’t take my word for it, but check it out yourself and get a copy from the QGIS website. Continue reading
GRASS GIS 6.4.3 released – Birthday release for 30 years of GRASS GIS on http://grass.osgeo.org
Good news, check it out: http://grass.osgeo.org/news/25/15/GRASS-GIS-6-4-3RC4-released/
The upcoming QGIS 2.0 will have some really cool and useful new features. Check for example out the latest blog posts by Anita Graser aka Underdark, where she takes you on a tour of all the new features of the all new print composer. There are six posts highlighting the following new features: guidelines, multi-column legends, overview maps, html labels, map grids and rules and guidelines.
At nyalldawson.net you can read more about the upcoming ‘blend modes for layers‘. These effects, previously only found in photo/image editors like GIMP or photoshop, will allow you to blend layers together using various effects. Another feature you would normally expect in GIMP or the like is colour control for raster layers. This allows you to tweak the saturation, hue, grey scale, etc.
There is a lot more coming, but these changes alone are really impressive!
Some time ago I came across this post from Sylla Consult about a script to calculate forest fragmentation index suggested by Riitters et al. (2000). Obviously, it can be used for any land cover type, so perhaps landscape fragmentation index would be a better name. Anyway, the script r.forestfrag.sh is available from the GRASS-addons page.
Unfortunately, it only worked with GRASS 6.4. Because I mostly work in GRASS 7.0 I adapted the script to make it work on GRASS 7.0. I also added some additional options and changes: Continue reading
