Thanks for support to Paolo Cavallini - Faunalia !
Can you give some detailed steps for OTB plugin in GRASS ?
Bets regards,
Dan

Hi Yves
Add a new directory called 'composer_templates' into /usr/share/qgis and
save template files into it ('Save as template' in print composer
window). The composermanager creates a new entry for each template in
that directory.
Btw, that functionality was developed for the edugeo project ;-)

Marco

there's no "if" operator, but ">" returns 1 if true and 0 if false,
e.g. (field > 5)*10 let's give you 10 or 0 as result.
The problem is that you don't want to display anything when
the field value is 0, so we can use the substr function.
Here's the solution to your problem:
substr(id, 0, (id > 0)*-1)
that means if id <= 0 then substr(id, 0, 0) else substr(id, 0, -1)
In general:
substr(output, 0, (condition)*-1)

Hi all.
I recently had reports about some instability of the GRASS plugin on windows.
(Un)fortunately I cannot test it, as I do not own a win licence, so I'm asking here:
* is this a common problem?
* can be related to anything specific?
- Win version
- installed software
- does it happen on "dirty" installations only, or also on clean ones?
- antivirus?
* when (at what QGIS version) has the problem arisen?
Thanks a lot.

Hi Dan [I already sent this, did you receive it?].
AFAIK there is nothing like Fragstat ready-made in QGIS. You have two routes:
- r.li (GRASS module), not yet implemented in QGIS, you'll need GRASS
- OTB plugin (methods should be added for the analyses you need).
All the best.

Hi all.
Wouldn't it be better using the /home dir instead of /usr/share/qgis for this?
All the best.

Hi,
I can confirm problems with output messages encoding [0] under
32 bit Windows XP Pro SP3, 32 and 64 bit Windows 7. This happen
on clean and dirty installations and seems not releated to any
specific software.

Hi Giuseppe,
Thanks for your hint with the syntax - it works in my case.
I think I sort of understand the syntax - at least the > operator and
the substr. What I do not understand is why I need the *-1 (multiplier).
But I think the syntax is far from being intuitive, without some help.
Maybe we can come up with a simple solution in the future?
If we could combine the rule-based renderer approach with the current
labeler (with its new query builder), it would be awesome.
Thanks for your help!
Andreas

Thanks for feedback - but this does not ionvolve any instability, right?

Agreed, I think we must use the same approach everywhere (renderer, field calculator,
raster calculator, actions), and the labelling approach is the best IMHO. Others are
often a bit geeky.
All the best.

It would be handy to add condition statements to QgsExpression so we can
support this kind of thing, Martin would be the guy to talk to about adding
this kind of thing. He knows the most about QgsExpression.
I am also looking at adding Python support to any sections that also use
QgsExpression; this would allow us to use a QGIS expression for simple-ish
stuff but also Python if need be for doing more powerful stuff.
I started a wiki page[0] before the last Hackfest about some of my ideas
about adding rule based labeling, which would be very cool to have.
