Indeed.
It took some time locate, but it was missing python-shapely installed.

Of course,

First, open the Metadata Catalog Plugin and put a default catalog service 
(whatever you want). 
Then, search for a wms typing "wms" on the search box
Next, click on a service/dataset  which has no the possibility to add it into 
QGIS using the WMS/WMTS button
Finally, click twice on the selected service/dataset and the message will 
appear automatically. That's my case.

Let me know if you have any doubt.

Vicent.

[Qgis-user] Metasearch plugin problem

2016-04-06 Thread Vicent García

Hi everyone,

 

Im having troubles to run Metasearch CSW plugin on QGIS 2.14. When I find a
dataset/layer which cant be added as a wms layer directly, I click on the
dataset located on the list in order to obtain more info about the data, but
a python error message appear inmediately. Typical error displayed is:
<> has no attributes.

 

Im using Lubuntu as a OS.

 

Vicent.

[QGIS-it-user] Conversione complessa vettore>raster e viceversa

2016-04-06 Thread Andrea Gagna

Ciao a tutti,
Utilizzo la versione 2.14.1 del QGis, che ha integrato il plugin del Grass
6.4.3.

Ho notato che non e' possibile (o non sono capace) convertire un raster i
cui pixel sono associati a codici RGB della scala dei colori che
definiscono sia "disegni" (non so come definirli in altro modo) puntiformi,
che multilineiformi che poligonali (esempio: raster in cui sono presenti
diversi colori per rappresentare diversi usi del suolo, tipo gli alberi
rappresentati da uno o piu' pixel dello stesso colore e attaccati l'un
l'altro,  che definiscono la loro forma circolare puntiforme, le case  dove
i pixel definiscono aree poligonali, e quelli che definiscono i fiumi).

Forse lo si puo' solo fare se converti un vettore di questa tipolpgia in
raster..

Ho visto che tramite funzione di conversione raster in vettore (e
viceversa)del plugin GRASS, puoi solamente convertire raster riconducibili
a geometri univiche; quindi solo da singolo raster con punti che
rappresentano gli alberi in vettore puntiforme o conversioni sempre solo da
singolo raster fiumi a vettore multilineiforme e da singolo raster case a
vettore poligonale...

Seconda domanda: ho importato un layer raster che rappresenta una Tavola
con i beni paesaggistici del PPR di una Regione dal suo Geo-portale tramite
servizio WMS (o WMF ora non ricordo).
Ho poi provato a salvare con nome tale raster ma non mi lascia farlo...Non
si puo' davvero, corretto?

Se volete maggiori dettagli per capire come aiutarmi posso fornirveli.

Grazie,
Gagna Andrea.

Perhaps related to https://trac.osgeo.org/gdal/ticket/6186

You need GDAL 1.11.4, 2.0.2 or 2.1.0beta1

Potrebbe pure essere un temporaneo problema di rete.
Magari riprovando più tardi funziona !

Fai anche questa prova: copia l'URL della repo direttamente nel browser e

Re: [Qgis-user] Current item @value in expressions

2016-04-06 Thread Neumann, Andreas

Hi Enrico, 

I can't tell why this expression fails, but there is a more elegant way
to distinguish between even and odd numbers. The modulus operator (%). 

CASE WHEN @atlas_featurenumber % 2 = 0 THEN --these are the even pages
   210 - @value
 ELSE --these are the odd pages
  @value
END 

The modulus operator returns the remainder after the divison - e.g. 5 %
2 returns 1, 6 % 2 returns 0, 7 % 2 returns 1, 8 % 2 returns 0 and so
on. 

Als note, that @atlas_featureid is not a good variable to use, because
it isn't always guaranteed that the is no hole in your primary key
sequence (e.g. if you delete features) - you would also run into
troubles if you start filtering features in the atlas. I would rather
suggest to use the variable @atlas_featurenumber. This should always
start at 1 and increment by one for each subsequent atlas record,
regardless of any filter or holes in the primary key sequence. 

Hope this helps, 

Andreas

Is there a way to get the current item value that is being modified by
expressions.
I would like to reformat my print composer atlas for two sided printing
referencing to @value variable without success:

CASE
WHEN  floor(  @atlas_featureid/2 )*2 =  @atlas_featureid  THEN 210 - @value
ELSE  @value

but I get always @value

Sometimes this is caused by plugins, "Globe" plugin is one of those known
for crashing at exit, try to disable it from the plugin manager.
