[Qgis-user] Clip raster with vectorlayer in Postgis

[Lene Fischer]

Hi Casper,
I need to be able to set the No data value – and in SAGA this option is not available.
It works in 2.99 – but my students still use 2.18 – (As you know ;-))

Hi Lene,

Using the Toolbox I get the option to use my vectorlayer from PostGIS. However I did not have any luck getting it to clip with the GDAL-clipper (Trying with a shape file there was no problem), but using the SAGA Clip raster with polygon works fine for me :)

Mvh. / Best regards

Hi
Just started to use PostGIS in QGIS. I only have vector data in postGIS
When I try to clip a raster layer with a vector mask (PostGIS) the layer is not shown in the drop down meny.
So I had to ‘Save As’ shape before clipping. Is this correct ?
