[Qgis-user] SQL Server Layer - field values not retrieved when using named ODBC DSN

Our organisation has just migrated from MapInfo TAB files to MS SQL Server Spatial. I'm using QGIS 2.8.2 to connect with data in a SQL Server 2008 R2 database. I have noticed unique field values are not retrieved when I create a connection using a previously created ODBC DSN. When I say "uniqu

[Qgis-user] Automated / saved work flows?

Hi QGISers, I'm wondering if there's a plug in or some way to save a series of steps in QGIS. One way I can think of doing it is to simply save the text / command line part of the gdal commands into a text / batch file which I could then use to string a series of command together, using the output

Re: [Qgis-user] Google Satellite and Measure line tool wrong results

Hi, All you need to do is to make a background shp that will not move, then zoom in with the Google layer until it shifts, and then zoom out. The shp file will help you Identify when the Google layer is in the correct place. Then, hide the vector layer and click on "save as image". Then load

Hello. Yes tnx. I don't have any problem with shp files and the measuring tool, only with the Google layers. I will have to load the sat images from another source Marco Il 06. 07. 15 02:48, Nicolas Cadieux ha scritto: > > Hi, > I guess you are using the open layer plugin. If so, Google la

Re: [Qgis-user] get length of "custom" geometry in expression

Kristian, thanks for your explanation. I will check the function editor. Richard, your solution would not solve my problem as I still use $length. But as a workaround I saved my layer in the CRS I needed and used the $length function in the label expression. Regards, Raymond On 06-07-15 09:0

Re: [Qgis-user] Vacuuming a vector polygon layer with a point layer in QGIS 2.8.2 (windows)

Hi Julie, Can you model it using the processing plugin?  This way, you could use the grass module from QGIS and that could automate the process if you need to do it often.  Look in the QGIS documentation for help on the creating a model. Nicolas Cadieux M.Sc. Les Entreprises Archéotec inc.  8

Re: [Qgis-user] Vacuuming a vector polygon layer with a point layer in QGIS 2.8.2 (windows)

I think this solution sounds great but I'm afraid I'm much too green using QGIS to know how to do it. When downloading QGIS I got the GRASS GIS 6.4.3 GUI and command line as well but I have never used it and don't know how to. I don't even know how to open the vector files in the GRASS program..

Re: [Qgis-user] get length of "custom" geometry in expression

The easiest way to do this is to create a new column for the length variable Just open the field calculator, leave the *create new field* box ticked, name your field in the *output field name* box set your field width and precision and in the expression box just type /*$length*/ Regards, Richa

Re: [Qgis-user] get length of "custom" geometry in expression

I think your problem is that length() returns the length of a text-string, and not the length of a geometry. As the geometry isn't a string, the output is 0. As far as I can see it is not possible to do what you want with the default functions in the field calculator. With a bit of python in the
