Since I don't understand how library (clustTool) can run, I test the
method described on the site that Dylan me advise ...
http://casoilresource.lawr.ucdavis.edu/drupal/node/340

#etape 1
#lecture de la table
x <- read.table ("vine", sep="|")
names(x) <- c('easting', 'northing', 'cat')

y <- data.frame(x[,1:2])
row.names(y) <- x$cat

plot(y, pch=3)

#etape2
#charger les librairies dont on a besoin...
library(cluster)
library(flexclust)
s <- stepFlexclust(y, K=2:10, nrep=20)

But I have a problem here

Erreur dans stepFlexclust(y, K = 2:10, nrep = 20) :

Thank you Leonardo, but I read it, without understanding much more about

Hi Susana,
can you explain the procedure to import vector?
because if you happened to import examples ... I think the function module.
Is that way you appear in your layer list vector

[GRASS-user] Cluster whit area?

[Etienne DELAY (deust 2010)]

Hello everyone
I work with GRASS GIS, and arrives on time where I need to do a bit of
statistics (aggregated plots clustered) so I turn to R. but I'm a noob,
in R to... Does someone can give me a hand for my fist R experience? I
installed R ... I find a module that area to do what I want : clustTool
(I hope). But now I do not know where to start ...
I have a vector layer into GRASS-GIS, which
contains parcel of vineyards across Europe. I would group them  in order
to propose a methodology for an inventory per cluster.
I hope this is clearer

 thank you :-)

Hello Vincent
first thank you for putting the good word on my request (though I
searched long), and thank you for french :-). In fact my brain is broke
down, si can you,  or others  give me an example with r.mapcalc or
r.reclass, for this request?
thank you ;-)

Bonjour Vincent
en premier merci d'avoir mis les bons mots sur ma demande (j'ai pourtant
cherché longtemps). En fait, mon cerveau fait un blocage.  Est-ce que
toi ou un autre pourriez me donner un exemple avec r.mapcalc, ou r.reclass?
Parce que je ne vois pas comment fonctionne ce type de requête.

Hello Nikos
sorry for the French, I need to think in my language :-)
So I have no problem using r.mapcalc for 1st and 2nd criteria, and to
assemble the two masks. The region is also parameterize, but now, it has
become a 3rd test, I must arrive in isolating the flat portions of the
mountain in Spain, if not that is reflected in part authorize my mask,
but not know  structural problems in they vineyards ...

I want to use something like:

r.mapcalc "Maskplate= if((Area>10ha && slope<=10%), 1, null())

mais l'utilisation de aire ne me satisfait pas vraiment parce quelle
peut changer en longueur et largeur...

but the use of area does not really satisfy me  because what can
change in length and width ...

Is there a solution would be to make visual grade, to define the
geomorphological unite?

thank you very much ;-)

[GRASS-user] create a mask to exclude plate area

[Etienne DELAY (deust 2010)]

Bonjour
Je travaille actuellement sur des problématiques liées à la viticulture
de montagne, qui répond a des critères bien précis (altitude supérieure
a 500, ou pente supérieure a 30%)à partir des données DRTM. J’ai donc
créé un masque qui permette de délimiter ces zones.
Maintenant je dois exclure les zones de plateau (par exemple les
plateaux espagnols) mais je n'arrive pas à visualiser quel critère
utiliser pour cela.
J’ai pensé faire une commande r.mapcalc avec une requête à la fois sur
la superficie, et sur la pente. Est-ce que vous pourriez m'aider à créer
ce masque?

Merci

Hello
I am currently working on issues related to mountain viticulture, which
responds to specific criteria (above a 500, or upper slope 30%) from
data SRTM. So I created a mask that allows to define these areas.
Now I have to exclude the plate areas (eg trays Spanish) but I can not
see any use for this test.
I thought r.mapcalc place an order with a request to both  area and on
slope. Can you help me to create this mask, or give me an idea?
thank you

Hi Syncrasy,
I work on a Mac and I found an alternative, I do background work on
GRASS, but once I want to do the layout, I go into Qgis to directly
integrate the work of grass ...

[Etienne DELAY (deust 2010)]

Hello
I am a Master (french) student, and I work in Valle d'Aosta on vines
issues . I'm a noob to 3 days. I discovered the potential of GRASS with
great pleasure. I wanted to know if it was possible to make remote
sensing (télédétection) with this fabulous software?
thanks
