comment How to represent trend over time?
Regression is a good idea. You can try also (last value - first value) / years, resulting in some Y units per year.

comment How do I use polygons to apply a unique value to all raster cells within those polygons?
While rasterizing polygons, in the Polygon To Raster dialog window, you need to go to Environments -> General settings and use Snap Raster option, to get the cells correspondent to your initial raster.

Thank you, looks interesting, I will investigate this method. And I also thought about getting values at vertices of polygons.

comment How can I see the coordinate transformation parameters in QGIS?
Yes, ETRS is just a case of luck for me. I am wondering what if I had two CRS different from WGS84, CRS1->WGS84->CRS2 is a rather crude way :(

comment How can I see the coordinate transformation parameters in QGIS?
Thanks for the answer, but it is not completely clear. In project settings, I've already changed the default WGS84 CRS to another one. So if I understand you correctly, QGIS see all coordinate systems as referred to geographic WGS84? And transformation from one local CRS of data to another CRS of the project anyway always goes through WGS84 like CRS1->WGS84->CRS2? (For EPSG 3763 (ETRS) I see +proj=tmerc +lat_0=39.66825833333333 +lon_0=-8.133108333333334 +k=1 +x_0=0 +y_0=0 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=m +no_defs, so 0,0,0,0,0,0,0 are the parameters, right)
