Re: [Qgis-user] nodata color in rasters
Nodata has a value: you can use a custom palette and asign a colour to that value. I suppose the Nodata value is the value automatically set as transparent under the tab Transparency in the raster's Layer Properties. In my case, this value is: -3.40282e+38. (other possible values? 255, -32768, , ... ?)

[Qgis-user] Symbology Export
Hi List, General curiosity question. When using Save Vector Layer as to save a vector layer, there's an optioon: Symbology Export This in turn has three options: No Symbology Feature symbology Symbol layer symbology What does this do? I've tried exporting to both KML and TAB files using these options but they don't appear to keep the symbology.

Re: [Qgis-user] Symbology Export
Hi Jonathan, This was originally introduced for DXF export to keep symbology as good as it can - which is now in its separate function (Project - DXF Export) and not in the save layer as anymore.

Re: [Qgis-user] Symbology Export
Hi, Actually it is not tied to DXF, but DXF was the reason why it was introduced. It is just generic OGR feature styling. Maybe it should be removed/hidden/disabled because DXF now has its separate export. Maybe assign Marco Hugentobler to this ticket as he worked on this.

Re: [Qgis-user] Symbology Export
Hi Andreas, I'm testing with a simple polygon that's using the default style QGIS gave it (so basically black border and a random fill colour). I've exported using both options - all I get in the KML file is a black border, no fill. I can change the colour of the border in QGIS and it changes in the KML file. So I guess that's a very partial implementation. *However* - If I set it to no symbology I still get the coloured boundary. So changing the value appears to do absolutely nothing which is I guess what I saw when I first tested it (a while back). Hence my wondering what it actually did. Can you confirm this behaviour? It seems superfluous to have an option that is ignored. Cheers, Jonathan On 10 March 2014 15:30, Andreas Neumann a.neum...@carto.net wrote: Hi Jonathan, The thread you are quoting is from 2011.

Re: [Qgis-user] Symbology Export
Hi Jonathan, I can only partially confirm what you describe. I agree that for area feature the feature styling does not work for KML. However, for line features, it works fine and there is a difference between the three options. The no symbology only exports a single line color, the feature symbology correctly exports the colors assigned to the categories and the symbol layer symbology exports line features multiple times in case of multiple levels in the line symbology. So I'd rather improve this than remove it. If someone could work on the area feature styling it would be great. Or maybe hook up with the OGR project if things don't work as expected.

Re: [Qgis-user] Symbology Export
Hi Andreas, Thanks for further testing. I figured if something as simple as a fill wasn't implemented then catogorisation probably wouldn't be. A further thought - not all vector formats support styling (shapefile being the most notable exception). Should it remain a general option or be moved to Datasource Options for any supported style? I lean towards the later option myself. Cheers, Jonathan On 10 March 2014 16:04, Andreas Neumann a.neum...@carto.net wrote: Hi Jonathan, I can only partially confirm what you describe.

Re: [Qgis-user] Symbology Export
Hi Jonathan, I think this option should be disabled if a format does not support feature styling. I don't know if OGR provides this information? http://www.gdal.org/ogr/drv_kml.html says about KML: Limited support is available for fills, line color and other styling attributes. Please try a few sample files to get a better sense of actual behavior. Andreas Am 10.03.2014 16:10, schrieb Jonathan Moules: Hi Andreas, Thanks for further testing. I figured if something as simple as a fill wasn't implemented then catogorisation probably wouldn't be. A further thought - not all vector formats support styling (shapefile being the most notable exception). Should it remain a general option or be moved to Datasource Options for any supported style? I lean towards the later option myself. Cheers, Jonathan On 10 March 2014 16:04, Andreas Neumann a.neum...@carto.net wrote: Hi Jonathan, I can only partially confirm what you describe. I agree that for area feature the feature styling does not work for KML. However, for line features, it works fine and there is a difference between the three options. The no symbology only exports a single line color, the feature symbology correctly exports the colors assigned to the categories and the symbol layer symbology exports line features multiple times in case of multiple levels in the line symbology. So I'd rather improve this than remove it. If someone could work on the area feature styling it would be great. Or maybe hook up with the OGR project if things don't work as expected. Andreas Am 10.03.2014 15:47, schrieb Jonathan Moules: Hi Andreas, I'm testing with a simple polygon that's using the default style QGIS gave it (so basically black border and a random fill colour). I've exported using both options - all I get in the KML file is a black border, no fill. I can change the colour of the border in QGIS and it changes in the KML file. So I guess that's a very partial implementation. *However* - If I set it to no symbology I still get the coloured boundary. So changing the value appears to do absolutely nothing which is I guess what I saw when I first tested it (a while back). Hence my wondering what it actually did. Can you confirm this behaviour? It seems superfluous to have an option that is ignored. Cheers, Jonathan On 10 March 2014 15:30, Andreas Neumann a.neum...@carto.net wrote: Hi Jonathan, The thread you are quoting is from 2011. The OGR feature styling was introduced later (in late 2012 or early 2013 I think). So did you really test KML export with Feature symbology or symbol layer symbology? I just tested it with QGIS master and with line features and different line colors. It worked. What did you do that it did not work? What steps? Do you have project/data to share?

I'll open a ticket for removing/hiding it.

It is just generic OGR feature styling. Maybe it should be removed/hidden/disabled because DXF now has its separate export. Maybe assign Marco Hugentobler to this ticket as he worked on this. Unless someone wants to work on it and improve it. Does it not work at all with KML? Not even a simple line color?

It uses the OGR feature styling, which in itself is rather limiting. This isn't widely implemented and tested. Would be nice if some devs or interested customers/users could give it some love.

Re: [Qgis-user] Labelling expressions: how to select the 'last' row in a csv dataset
Gavin, Set up the CSV file creation to append to the top of the file instead of the bottom, then just read the first line for the special cartography. If you are running on Linux, there are a whole bunch of options with AWK/GREP, etc to get the data outputting in a more favorable fashion for reading. My first thought was to suggest the SQL path though, this gives you lots of options for archiving and looking at the path/trail over time . . . I've just completed doing something similar for a AVL tracking system.

[Qgis-user] diagrams and labels in the same map
Hi All, I would like to create a map with diagrams and, in the same time, labels displayed on it. I have tried several ways but when I put the labels on the map, diagrams always move to another place. Is there a possibility to fix their places? And, later when I add the labels to move them to a proper place? A not too elegant solution was to save the map with the diagrams as a raster with a world file and than use it as a background, next step I added the labels and move them where they looked fine. But is there a normal way? I am using QGIS 2.2 32 bit on Win7 Thanks in advance, Szilard ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
Re: [Qgis-user] Labelling expressions: how to select the 'last' row in a csv dataset
Hi Gavin, Can you have the row written to two files concurrently? One as an append one overwrite. Both watched in QGIS have the overwrite as the upper layer on the map with a different symbol, thus overwriting the trackline point in the append csv file. Not as elegant as an SQL solution, but csv's are not really reknowned for their elegance in data management :-) I haven't really thought this through, but you might try using a named pipe (see mkfifo on Linux, Windows has something along these lines too), run tail -n 1 -f myfile.csv into the named pipe, then open this in QGIS. This is such a horrible solution it's almost certain not to work, but you never know :-) Cheers, Brent From: Gavin Macaulay ga...@macaulay.co.nz To: qgis-user@lists.osgeo.org Sent: Tuesday, March 11, 2014 9:18 AM Subject: [Qgis-user] Labelling expressions: how to select the 'last' row in a csv dataset Hi, I have a csv file that looks like this: datetime, latitude, longitude, speed 2014-03-07T06:11:56.794000, 69.6930, 19.0321, 0.0 2014-03-07T06:12:56.791000, 69.6904, 19.0291, 10.0 2014-03-07T06:13:56.787000, 69.6879, 19.0257, 10.0 A new row gets added to the file every second or so.
