Re: [Qgis-user] Adding alpha band to raster

[Nicolas Cadieux]

Hi,

I don't see it in the current processing algorithms. I see lot's or 
r.out... but not that one:(  I guess I could do it in Grass...


Thanks for the idea!

Alpha bands are handy with the georeferencer. Currently, I am just 
adding it in GIMP before I start the georeferencer.

Hi,

bands are handy with the georeferencer.  Currently, I am just adding it in GIMP

Re: [Qgis-user] Import kml with all the fields

[C Hamilton]

KMLs can be difficult to work with. In your case the Fields are actually an
HTML block of text that is contained in the description field of the KML.
KML Tools will work with this, but there are two steps that you need to
take. The first is to import the KML file into QGIS. Install the KML Tools
plugin and run "Vector->KML Tools->Import KML/KMZ" from the QGIS menu. All
of your tables are in the description attribute field. The next step is to
select this imported layer and run "Vector->KML Tools->Expand HTML
Description Field". For "Input layer" select your imported KMZ data.
Description field will automatically be set to description. "How to expand
the description field" should be set to "Expand from a 2 column HTML
Table". Click on OK. It will ask you what fields from the table you want
expanded. Select what you want and then click on OK.

This works for the KMZ file you sent.

Best wishes,

Calvin

this kmz to QGIS and open the attribute table, I cannot see any of these

Re: [Qgis-user] Import kml with all the fields

[C Hamilton]

Because of the free-form nature of how KMLs can be constructed, they can
sometimes be challenging to interpret. Try the KML Tools plugin

https://plugins.qgis.org/plugins/kmltools/

It uses a different methodology to interpret KML/KMZs than what is in QGIS.
Since I am the author of that plugin, if it does not work send me a copy of
the KML and I will try to make sure it works for your case.

Best wishes,

Calvin

Hey Miquel,

make sure the data type of the field you want to insert the result to 
matches the data type of the result itself. You might need to convert an 
array to a string if I understand you correctly.
