Hi,

You can do either:

* concatenate multiple attributes in one label, even with line breaks
* or load the same layer twice with different label settings

Other than that there is no way to have two different label settings on
the same layer while the layer is only loaded once.

Re: [Qgis-user] GDAL Fill nodata Algorithm

[Nicolas Cadieux]

Not sure.  Where do you see that?  A Mask is usually a raster file 
with zeros and ones.  It will permit you to cut or modify another raster 
to a specific shape by multiplying it to the mask.  I imagine a validity 
mask is asked if you what to first validate an area you want to modify.

You can combine different attributes in one label using the expression
button, and separating the attributes with the // button

Hope this helps

Hi,

You can do either:

* or load the same layer twice with different label settings

Other than that there is no way to have two different label settings on 
the same layer while the layer is only loaded once.

I thought about something of that sort, but in my case having data in a

Anyway your solution seems to work, I'll keep it for future reference.

Re: [Qgis-user] Conditional Value Mapping

[Víctor Manuel Herreros Villanueva]

Dear André,

I asked for the same problem months ago without obtaining any answer. As
far as I know, there is no QGIS feature implemented that allows you to
achieve what you are looking for.

So I decided to dive into my underlying PostgreSQL databse structure. The
solution I chose was the following: Two reference tables with data
description and one table with data for the user affected by one constraint.

*Reference table for attribute 1 (ATTR1_TABLE)*
--  
ID  Textf
--  
01  Agriculture (01)
02  Forest (02)
--  

*Reference table for attribute 2 (ATTR2_TABLE)*
-  --
ID Textf
-  --
01.01  Corn (01.01)
01.02  Wheat (01.02)
02.01  Pines (02.01)
02.02  Olives (02.02)
-  --

*Structure of the table containing the data to be shown to the final user
(DATA_TABLE)*
attrib1_cod: character varying(9)
attrib1_desc: character varying(100)
attrib2_cod: character varying(9)
attrib2_desc: character varying(100)

Then I stablished the appropriate *database constraint*:

ALTER TABLE DATA_TABLE
  ADD CONSTRAINT data_table_cc_attr2 CHECK (attrib2_cod IS NULL OR
attrib2_cod::text = ''::text OR "substring"(attrib2_cod::text, '^..'::text)
= attrib1_cod::text);

With this constraint, you ensure that the data to be introduced in
ATTR2_TABLE ID field must contain in the string beginning one of the values
present in ATTRIB1_TABLE ID field. So, if your user has selected
attrib1_cod/attrib1_desc 01/Agriculture (01) for DATA_TABLE, then, when
fullfilling attrib2_cod field he only can choose the values 01.01 or 01.02,
because both of them start with the string '01'.

Well, he can really choose any value for attrib2_cod, but only the
appropriate ones won't throw insertion errors.

The problem with this workaround is that the user can choose any value for
attr2_cod field. But, if you decide to show him just the descriptive text
fields, he can easily see which ones are proper values (because in the tex
field all records end with the numeric code).

I've personally decided to use just the numeric values for my users. So,
under QGIS, and through a widget (value map), I show my users the fields
attrib1_cod and attrib2_cod, but with the values taken from the text fields:

*Value map widget for attrib1_cod*
-  
Value  Description
-  
01 Agriculture (01)
02 Forest (02)
-- 

When the user selects from the drop down list the description 'Agriculture
(01)', he is really selecting the value '01' for attrib1_cod. The same
applies to attrib2_cod:

*Value map widget for attrib2_cod*
-  --
Value  Description
-  --
01.01  Corn (01.01)
01.02  Wheat (01.02)
02.01  Pines (02.01)
02.02  Olives (02.02)
-  --

And finally, in order not to ask the user to fullfill the field
attrib*_desc (cause he has previously fullfilled attrib*_cod but from
descriptive values), I have two more triggers and trigger functions whose
mission is to fill in the descriptive fields provided the code fields have
been modified:

*Trigger for attrib1_desc on table DATA_TABLE*
CREATE TRIGGER update_attrib1_desc
  BEFORE INSERT OR UPDATE
  ON DATA_TABLE
  FOR EACH ROW
  EXECUTE PROCEDURE update_attrib1_desc();

*Trigger function for called by the previous trigger*
CREATE OR REPLACE FUNCTION update_attrib1_desc()
  RETURNS trigger AS
$BODY$
  DECLARE
  BEGIN
IF (TG_OP = 'INSERT' OR TG_OP = 'UPDATE' ) THEN
  NEW.attrib1_desc := (SELECT Textf FROM ATTR1_TABLE WHERE ID =
NEW.attrib1_cod);
  RETURN NEW;
ELSE
  RETURN NULL;
END IF;
  END;
$BODY$
  LANGUAGE plpgsql VOLATILE
  COST 100;

So each time an attrib1_cod field is entered or updated, the trigger seeks
for the appropriate attrib1_desc field and writes it into attrib1_desc
field.

And the same for attib2_desc:

*Trigger for attrib2_desc on table DATA_TABLE*
CREATE TRIGGER update_attrib2_desc
  BEFORE INSERT OR UPDATE
  ON DATA_TABLE
  FOR EACH ROW
  EXECUTE PROCEDURE update_attrib2_desc();

*Trigger function for called by the previous trigger*
CREATE OR REPLACE FUNCTION update_attrib2_desc()
  RETURNS trigger AS
$BODY$
  DECLARE
  BEGIN
IF (TG_OP = 'INSERT' OR TG_OP = 'UPDATE' ) THEN
  NEW.attrib2_desc := (SELECT Textf FROM ATTR2_TABLE WHERE ID =
NEW.attrib2_cod);
  RETURN NEW;
ELSE
  RETURN NULL;
END IF;
  END;
$BODY$
  LANGUAGE plpgsql VOLATILE
  COST 100;


A little bit confusing, but I haven't found any other way to solve the
problem...

Best regards.

qgis-globe-plugin, qgis-grass-plugin and qgis-oracle-provider belong to "qgis",

You don't need any of those to run "qgis-rel-dev", but you also don't need to
deinstall "qgis" to install "qgis-rel-dev".  It's not split into sub packages
(like the master build qgis-dev).

After installing you should have a shortcut to "QGIS Desktop 2.8.1 (Nightly)"
that starts the nighly of 2.8.

Re: [Qgis-user] GDAL Fill nodata Algorithm

Hello Nicolas,
I have further questions concerning the use of the algorithm!

Is it right that the no-data values must be represented by 0 so that
the interpolation works properly then?

[Qgis-user] Conditional Value Mapping

[ALT SHN]

Hi,

I am looking for a way to implement conditional value mapping in QGIS. This
means that the values available in attribute number 2 depend on the value
provided in attribute 1.

Example:

If the user enters "agriculture" in attribute 1, for attribute 2 only
"corn" or "wheat" will be available.

Instead, if the user enters "forest" in attribute 1, for attribute 2 only
"pines" or "olives" will be available.

And so on...

Apparently this is not doable just using the QGIS widget expression
builder, but I am not sure. Here's a screencast to help visualize. The
problem is that if for "class" I pick other than "Agri_Field", for the
"color_aggri" attribute the same possible values appear.

Thanks in advance for any hints!


Regards,


Andre

[Qgis-user] QGIS-rel-dev doesn't install alone

[Hillers Heather]

We really need qgis 2.8.2 on our productive system to fix an oracle bug that is 
for us critical and becoming more and more critical as we get more users.  We 
were waiting for the point release to come, but this week we decided it was 
better not to wait and just install the qgis-rel-dev as our production version 
until the point release came.  However, when we run OSGeo4W and try to 
uninstall the qgis module and install the qgis-rel-dev module, it doesn't work. 
 We end up with qgis and qgis-rel-dev anyway, and 2 start menu items.

We get the dependency notice, qgis required by qgis-globe-plugin, 
qgis-grass-plugin, qgis-oracle-provider.  We definitely need qgis-grass-plugin 
and qgis-oracle-provider.  How can we get a clean install of qgis-rel-dev?

Thanks,

heather
