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

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

Re: [Qgis-user] Import kml with all the fields
Hello, I am herewith attaching the kmz. When I open this in google earth, I can see all the four fields;Field1,Field2,Field3 and Field4. But, when I add this kmz to QGIS and open the attribute table, I cannot see any of these fields. This is just a sample data. I have about 50 to 60 such kmzs. Can you please suggest as permanent solution so that I can fix it myself and see all the four fields? Regards.

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

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.
