Hi Manuel,<div>I also suggest you to consider the analysis tools provided by Sextante [1]. It offers "bridges" to other GIS analysis software, like GRASS and SAGA, and they have a lot of analysis functionalities and algorithms.</div>
<div>For example GRASS has the r.li.* [1 ]set of commamds for landscape analysis.</div><div><br></div><div>giovanni</div><div><br></div><div>[1] <a href="http://plugins.qgis.org/plugins/sextante/">http://plugins.qgis.org/plugins/sextante/</a></div>

<br></div><div>I will check all the stuff you suggested.</div><div><br></div><div>
I teach landscape ecology and wildlife habitat evaluation for master students, I use R for some topics, but I want use more QGIS and stay away from commercial software. Our students (from all over Latin America) usually work under very restrictive budgets.</div>

I am not aware of any specific tutorials for doing this work in QGIS.<br>
<br>
No offense but these tasks are relatively basic. Your comment "I found this task kind of difficult to do in QGIS" is suggestive that you have difficulty in either basic GIS concepts or extrapolating your existing knowledge from a commercial package to QGIS.<br>
<br>
*Assuming you stick with QGIS*<br>
<br>
Micha Silver has provided a tutorial called "GIS basics with Quantum GIS" <a href="http://www.osgeo.org/node/1058" target="_blank">http://www.osgeo.org/node/1058</a> that may help you master the basics.<br>
<br>
The QGIS website has a great section called "How do I do that in QGIS?" that covers alot of material <a href="http://hub.qgis.org/projects/quantum-gis/wiki/How_do_I_do_that_in_QGIS#How-do-I-do-that-in-QGIS" target="_blank">http://hub.qgis.org/projects/<u></u>quantum-gis/wiki/How_do_I_do_<u></u>that_in_QGIS#How-do-I-do-that-<u></u>in-QGIS</a>. Note the large number of videos on youtube -- sometimes seeing it done can help.<br>
<br>
*Assuming you are considering an alternative*<br>
<br>
The OSGeo Educational Content Inventory also has a wide variety of other educational material available that might also help fill in the gaps. <a href="http://www.osgeo.org/educational_content" target="_blank">http://www.osgeo.org/<u></u>educational_content</a><br>
<br>
Finally, QGIS is not the only fosGIS out there. Check out what is on offer on the LiveDVD (<a href="http://wiki.osgeo.org/wiki/Live_GIS_Disc" target="_blank">http://wiki.osgeo.org/wiki/<u></u>Live_GIS_Disc</a>).<br>
<br>
Personally, I found using gvSIG relatively easy when moving from ArcView. Unfortunately the bulk of the tutorials are in Spanish; unlike QGIS which are predominantly in English. See my website for details and a list of ecological tutorials I have prepared to date.<br>
<br>
*Final Comment*<br>
<br>
All this material is predicated by the premise that you actually know what things are called. Reprojection and transformation is a good example. Projection, SRS and CRS another. When stuck, posing a problem on the forums can help as others can help you with terminology and suggest methods to solve you problems.<br>
<br>
I hope this helps.<div><br>

What I am trying to do is a very common task in landscape ecology. The<br>
buffer could be considered a landscape for some species and some metrics<br>
could be obtained for these "landscapes", however, I found this task<br>
kind of difficult to do in QGIS. Any input on this? Is there any<br>
oriented landscape ecology tutorial for QGIS.<br>
