[Qgis-user] Add a shape within QGIS to a record already in a database layer/table (SQL SERVER)
Hi everyone, Is there a way to add a shape (eg polygon) to a record in a database table added to QGIS, where the record was originally created in a database form elsewhere. (probably makes more sense as an example). In my SQL Server database form I create a new record for a mine site in a table that has a geography field. I then go into QGIS, load the layer/table via the SQL Server connection. I now want to create a polygon shape associated with the new mine site record I created. Typically I would just edit the existing shape associated with the record, but since there is no shape associated with this record, it doesnt appear there is a way to create a shape to associate to an existing record. Is this possible (all of my attempts say no). Is there a better way for this workflow to happen. I could create a child table to house the geometry and then use a key relationship to associate it to the record but I want as few tables as possible as this adds tables increases complexity for novice users. Thoughts?

Re: [Qgis-user] Add a shape within QGIS to a record already in a database layer/table (SQL SERVER)
Hi, not sure about MySql (I use PostgreSQL). How if you define a default polygon that is used upon inserting a new dataset with null polygon (needs a trigger maybe). You can later change that polygon in QGIS. IMHO the better way would be to create the dataset from within QGIS by digitizing the new polygon, though.

Re: [Qgis-user] Add a shape within QGIS to a record already in a database layer/table (SQL SERVER)
You can create a SQLServer based insert trigger, that checks the new record. If the record doesn't contain a geometry object (geometry is null) it can create a dummy geometry before inserting the record in the database, for example a polygon square. The position of the square should be determined by some other information in the new record, so every dummy square has an unique position.

Re: [Qgis-user] Add a shape within QGIS to a record already in a database layer/table (SQL SERVER)
I have seen this case scenario before, and I think this can be a good Plugin Idea. something that would allow to: - Add a geometry to a record\feature without any geometry (must have a geometry column already); - Replace an existing geometry (having a dummy geom at some time you will want to give a proper one); - remove the geometry from the record\feature; Alexandre Neto On Tue, Jun 17, 2014 at 9:53 AM, Bo Victor Thomsen bo.victor.thom...@gmail.com wrote: You can create a SQLServer based insert trigger, that checks the new record.

[Qgis-user] QGIS-Merge or creat virtual raster files without losing definition?
I am new to QGIS and relatively new to GIS (so please be aware I am not that familiar with jargon). I am trying to merge several tiff files as either a virtual raster or a simple merge. Whichever way I try the resulting display appears to lose definition (even just a couple of the files). I have tried to set the options to no compression (merge rasters), and resolution set at highest for creating virtual raster, but street names and place names still become too pixillated to read properly. This does not happen if I load all the files I wish to merge individually, but obviously I would rather work with the merged or virtual files. I am using QGIS 2.2.0 on a 2.5 GHz Intel Core i5 Mac, OSX 10.9.3. Would appreciate some help, please.

Re: [Qgis-user] Clipping tool in v2.2 valmiera Mac version
I don't think the CRS matters. Are you clipping a raster or vector? Clipping to another shapefile or just a box? I've only clipped rasters, and only to a box not a shapefile. Maybe others on the list will have insights. Does it give you any message when it fails? On Jun 17, 2014, at 9:34 AM, neumann t.
