I'm new to Qgis. I have experinece with Arc and TNTMips.
At the moment I'm working with habitats and Fragstat can anyoane give me some hints where to start in QGIS?
I have two rasters one is the auto- classification and the other one is the mask with 0 for habitats, 1 for background and -1 for external background, limits (border).
Thnaks,
Merry Christmas,
Dan

This is not true: QGIS is adopted widely. The fact is that most organizations use it
as it stands, either because they think it is good enough for them, or because they
do not want (have the resources for) invest on it.
Good examples, of organizations investing to improve qgis, are around, and are
increasing. Of course we all would like the quality and functions to improve much
faster than they do, but in general I think things are not going bad.

Well said. So why you and others are not investing in the new analytical framework,
to bring together the full power of these and other sw? Without an investment,
development will obviously be far slower.
All the best.

Hi Henry,
what is the column format of the csv? Is there already some column in
the data on which you can 'know' if the point is good or bad?
If that is the case, you can use the 'Add Delimited Text Layer'-plugin
to just load your dat in QGIS.
Then you use a 'Categorized Style' (see 'Layer
Properties'/Style-tab/...) and choose the column with your two states
good/bad.
Push button 'Classify' and optionally change color by clicking on the
colored dots in that dialog.
Both for using the 'Add Delimited Text Layer'-plugin and about
Categorized classification for styles, see documentation:
http://qgis.org/en/documentation/manuals.html
Hope this helps,
Richard Duivenvoorde

Thanks a lot to Giovanni for having checked.
I wondered where the difference of behaviour comes from.
In fact, when the CRS is set in project properties TO EPSG: 3035, both
shapefiles match as Giovanni noticed it. But when the project-wide CRS
is set to EPSG: 31370, the shift appears.
Here is a link to both screenshots:
http://www.yousendit.com/download/T2dlak80YXliR0pBSXRVag.
As I explained in a former mail, this shift appears in QGIS 1.7.2 and
not in 1.6.
If you want to have a try, here are the links to the freely donwloadable
shapefiles:
- belgian (Walloon Region) Natura 2000 limits:
http://environnement.wallonie.be/cartosig/telechargement/NATURA2000_DIFFUSION_BASE_MARS2010.zip
use "NATURA2000_PERIMETRES.shp".
- european Natura 2000 limits:
www.eea.europa.eu/data-and-maps/data/natura-2000 (I use the 2009
version)
NB: I can manage without the european data. I reported this as it might
help bug tracking and debugging.
Is this a bug of 1.7.2.? Should I file a ticket?
Thanks for all
Paul

Did you see this http://gis-lab.info/qa/road-graph-eng.html? Also you can use
pgRouting (PostGIS) and VirtualNetwork (SpatiaLite)

You don't need to configure or build QGIS with pgRouting. Just use your DB
as ordinal DB and simply execute queries with DB Manager or similar plugin

hi Richard,
thanks for reply.
The way of Categorized Style surely make the dot seem different.But I
hope to put all thing predefined in that csv file,because
I need output the csv from another software and then import qgis to get the
glance of whole state of these dots.This operations will be a little bit
more frequent and the dot actually has three or more different states,so I
want to simply the operations as much as possible.
I guess put everything in that a single file is a simple way but i dont't
know wether it is feasible in QGIS?
